Set a breakpoint on malloc_error_break() by opening the Breakpoint Navigator (View-&gt;Navigators-&gt;Show Breakpoint Navigator or ⌘8), clicking the plus button in the lower left corner, and selecting &quot;Add Symbolic Breakpoint&quot;. In the popup that comes up, enter `malloc_error_break` in the Symbol field, then click Done.

EDIT: openfrog added a screenshot and indicated that he&#39;s already tried these steps without success *after* I posted my answer. With that edit, I&#39;m not sure what to say. I haven&#39;t seen that fail to work myself, and indeed I always keep a breakpoint on malloc_error_break set.

In your screenshot, you didn&#39;t specify any module: try setting &quot;libsystem_c.dylib&quot;

![enter image description here][1]

I did that, and it works : breakpoint stops here
(although the stacktrace often rise from some obscure system lib...)

I had the same problem with Xcode. I followed steps you gave and it didn&#39;t work.
I became crazy because in every forum I saw, all clues for this problem are the one you gave.
I finally saw I put a space after the malloc_error_break, I suppressed it and now it works.
A dumb problem but if the solution doesn&#39;t work, be sure you haven&#39;t put any space before and after the malloc_error_break.

Hope this message will help..


I had given permissions I shouldn&#39;t have to write in some folders (especially /usr/bin/), and that caused the problem. I fixed it by opening Disk Utility and running &#39;Repair Disk Permissions&#39; on the Macintosh HD disk.

I solve it by close safari inspector. Refer to my **[post][1]**. I also found sound sometimes when I run my app for testing, then I open safari with auto inspector on, after this, I  do some action in my app then this issue triggered.

How to I make the markers in Android Google Maps API v2 become clickable so they will either bring up a menu with options or just start a new activity? I believe I made the markers in my app currently in a &quot;newb&quot; method. I didn&#39;t assign them a name or a method to be able to link it in with the rest of the required code.
 
    googleMap.addMarker(new MarkerOptions()
            .position(latLng)
            .title(&quot;My Spot&quot;)
            .snippet(&quot;This is my spot!&quot;)
            .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));


If you ANSWER this, please include a sample code of a marker being introduced with a unique name and then being set as clickable to open a new activity.

I have a data frame, like so:

    data.frame(director = c(&quot;Aaron Blaise,Bob Walker&quot;, &quot;Akira Kurosawa&quot;, 
                            &quot;Alan J. Pakula&quot;, &quot;Alan Parker&quot;, &quot;Alejandro Amenabar&quot;, &quot;Alejandro Gonzalez Inarritu&quot;,

                            &quot;Alex Proyas&quot;, &quot;Alexander Hall&quot;, &quot;Alfonso Cuaron&quot;, &quot;Alfred Hitchcock&quot;, 
                            &quot;Anatole Litvak&quot;, &quot;Andrew Adamson,Marilyn Fox&quot;, &quot;Andrew Dominik&quot;, 
                            &quot;Andrew Stanton&quot;, &quot;Andrew Stanton,Lee Unkrich&quot;, &quot;Angelina Jolie,John Stevenson&quot;, 
                            &quot;Anne Fontaine&quot;, &quot;Anthony Harvey&quot;), AB = c(&#39;A&#39;, &#39;B&#39;, &#39;A&#39;, &#39;A&#39;, &#39;B&#39;, &#39;B&#39;, &#39;B&#39;, &#39;A&#39;, &#39;B&#39;, &#39;A&#39;, &#39;B&#39;, &#39;A&#39;, &#39;A&#39;, &#39;B&#39;, &#39;B&#39;, &#39;B&#39;, &#39;B&#39;, &#39;B&#39;, &#39;B&#39;, &#39;A&#39;))

As you can see, some entries in the `director` column are multiple names separated by commas. I would like to split these entries up into separate rows while maintaining the values of the other column. As an example, the first row in the data frame above should be split into two rows, with a single name each in the `director` column and &#39;A&#39; in the `AB` column.

I have an All Exceptions breakpoint configured in Xcode:

![screenshot of an exception breakpoint configured in Xcode breakpoint pain, configured to make a sound when an exception is thrown][1]

Sometimes Xcode will stop on a line like:

&lt;!-- lang: objective-c --&gt;

    [managedObjectContext save:&amp;error];

with the following backtrace:

![backtrace showing NSPersistentStoreCoordinator throwing an exception inside the call to save:][2]

but the program continues on as if nothing happened if you click Continue.

__How can I ignore these &quot;normal&quot; exceptions, but still have the debugger stop on exceptions in my own code?__

(I understand that this happens because Core Data internally throws and catches exceptions, and that Xcode is simply honoring my request to pause the program whenever an exception is thrown. However, I want to ignore these so I can get back to debugging my own code!)

*Moderators: this is similar to [&quot;Xcode 4 exception breakpoint filtering&quot;][3], but I think that question takes too long to get around to the point and doesn&#39;t have any useful answers. Can they be linked?*

iPhone app could not be installed at this time

So, it finally happened. The worst case scenario for any independent iPhone developer occurred. Several users are reporting complete **data loss** after upgrading my app. iCloud Core Data sync is not working. My users are using this app partially to run their businesses. This is a truly *catastrophic failure*.

The only iCloud related thing I changed was to add the key-value store to iCloud. The core data code remained exactly the same, same model version (no migration) etc.

In my tests everything worked beautifully! But to my dismay, users reported that their data was not there anymore when they opened the updated app. 

What could be the reason for this? 

- The *persistent store URL* (an ubiquitous URL) should not have changed. 
- *Merge conflicts* are also unlikely, as this problem should have arisen before the update.
- &lt;strike&gt;Some interference with the new *ubiquitous key-value store* perhaps?&lt;/strike&gt;    
(I have pretty much ruled this out.)

Below please find the code for my managed object model and persistent store. Let me know if you need anything else to assess the problem. 


    - (NSManagedObjectContext *)managedObjectContext {
        
        if (managedObjectContext_ != nil) {
            return managedObjectContext_;
        }
        
        NSPersistentStoreCoordinator *coordinator = [self persistentStoreCoordinator];
        if (coordinator != nil) {
            managedObjectContext_ = [[NSManagedObjectContext alloc] initWithConcurrencyType:NSMainQueueConcurrencyType];
    		[managedObjectContext_ performBlockAndWait:^{
    			[managedObjectContext_ setPersistentStoreCoordinator:coordinator];
    			if (useICloud) {
    				[managedObjectContext_ setMergePolicy:NSMergeByPropertyObjectTrumpMergePolicy];
    				[[NSNotificationCenter defaultCenter] addObserver:self
               selector:@selector(mergeiCloud:)
               name:NSPersistentStoreDidImportUbiquitousContentChangesNotification
               object:coordinator];
    			}
    		}];
        }
        return managedObjectContext_;
    }

and 

    - (NSPersistentStoreCoordinator *)persistentStoreCoordinator {
        if (persistentStoreCoordinator_ != nil) {
            return persistentStoreCoordinator_;
        }
    
    	NSMutableDictionary *options = [NSMutableDictionary dictionary];
    	NSURL *storeURL = [[self applicationDocumentsDirectory] 
                URLByAppendingPathComponent:@&quot;SalesCalls.sqlite&quot;];
        
    	[options setObject:[NSNumber numberWithBool:YES] 
                      forKey:NSMigratePersistentStoresAutomaticallyOption];
    	[options setObject:[NSNumber numberWithBool:YES] 
                      forKey:NSInferMappingModelAutomaticallyOption];
    	
    	if (useICloud) {  // this is an internal flag set to YES
    		NSURL *iCloudURL = [[NSFileManager defaultManager] 
                                   URLForUbiquityContainerIdentifier:nil];
    		
    		if (nil!=iCloudURL) {
    			NSString *cloudData = [[iCloudURL path] 
                           stringByAppendingPathComponent:@&quot;data&quot;];
    			iCloudURL = [NSURL fileURLWithPath:cloudData];		
    			
    			[options setObject:@&quot;at.topofmind.salesplus.store&quot; 
                            forKey:NSPersistentStoreUbiquitousContentNameKey];
    			[options setObject:iCloudURL 
                            forKey:NSPersistentStoreUbiquitousContentURLKey];
    			
    			NSURL *nosyncDir = [iCloudURL 
                            URLByAppendingPathComponent:@&quot;data.nosync&quot;];
    			[[NSFileManager defaultManager] createDirectoryAtURL:nosyncDir

                            attributes:nil error:nil];
    
    			storeURL = [nosyncDir 
                            URLByAppendingPathComponent:@&quot;SalesCalls.sqlite&quot;];
    		}
    	}
        
        NSError *error = nil;
        persistentStoreCoordinator_ = [[NSPersistentStoreCoordinator alloc] 
                 initWithManagedObjectModel:[self managedObjectModel]];
    	if (![persistentStoreCoordinator_ 
                      addPersistentStoreWithType:NSSQLiteStoreType
                      configuration:nil URL:storeURL options:options error:&amp;error]) 
       {
    		NSLog(@&quot;Cannot create persistent store coordinator, %@, %@&quot;, 
                            error, [error userInfo]);
    		abort();
        }    
        
        return persistentStoreCoordinator_;
    }

Comments, opinions, wild guesses etc. (and of course solutions!) are all welcome. 

**UPDATE:** 

One of my customers lost all his data and after reinstalling and resetting everything (rebooting device, etc.) he could not sync with iCloud any more. The symbol simply does not show up in the Settings.

I am currently making an application that uses a custom View Controller container. Multiple views are on the screen at one time and when one is tapped, the selected view controller animates to full screen. In doing so, the selected view controllers subviews scale as well (frame, font size, etc.) Though, UILabel&#39;s font property is not animatable leading to issues. I have tried multiple solutions but all flat out suck.

The solutions I have tried are: 

 1. Take a screenshot of the larger view and animating the change (similar to how Flipboard does)
 2. Animate by using the transform property 
 3. Zooming out a UIScrollView and zooming it in when brought to full screen.
 4. Setting adjustsFontSizeToFitWidth to YES and setting the fontSize prior to animation 

One has been the best solution so far but I am not satisfied with it.

I&#39;m looking for other suggestions if anyone has any or a UILabel substitue that animates smoothly using [UIView animate..].

Here is a good example that is similar to what I would like my UILabel to do:
http://www.cocoawithlove.com/2010/09/zoomingviewcontroller-to-animate-uiview.html

**EDIT: This code works**


    // Load View

    self.label = [[UILabel alloc] init];
    self.label.text = @&quot;TEXT&quot;;
    self.label.font = [UIFont boldSystemFontOfSize:20.0];
    self.label.backgroundColor = [UIColor clearColor];
        
    [self.label sizeToFit];
    
    [self.view addSubview:self.label];

    // Animation

    self.label.font = [UIFont boldSystemFontOfSize:80.0];
    self.label.transform = CGAffineTransformScale(self.label.transform, .25, .25);
    [self.label sizeToFit];
    
    [UIView animateWithDuration:1.0 animations:^{
        self.label.transform = CGAffineTransformScale(self.label.transform, 4.0, 4.0);
        self.label.center = self.view.center;
    } completion:^(BOOL finished) {

        self.label.font = [UIFont boldSystemFontOfSize:80.0]; 
        self.label.transform = CGAffineTransformScale(self.label.transform, 1.0, 1.0);
        
        [self.label sizeToFit];

    }];



Animating UILabel Font Size Change

I have a theoretic question. Now İ&#39;m reading Apple&#39;s [ViewController][1] guide.

They wrote: 

&gt; When it comes time to dismiss a presented view controller, the
&gt; preferred approach is to let the presenting view controller dismiss
&gt; it. In other words, whenever possible, the same view controller that
&gt; presented the view controller should also take responsibility for
&gt; dismissing it. Although there are several techniques for notifying the
&gt; presenting view controller that its presented view controller should
&gt; be dismissed, the preferred technique is delegation.

But I can&#39;t explain, why I have to create a protocol in presented VC and add delegate varible, create delegate method in presenting VC for dismissing presented VC, instead of a simple call in **presented** view controller method 

`[self dismissViewControllerAnimated:NO completion:nil]`? 

Why is the first choice better? Why does Apple recommend it?

I know it&#39;s possible to link directly to an app in iOS by registering a custom scheme (e.g. so://) and it&#39;s also possible to link to the app in the appstore via itunes.

In many cases, the ideal flow is to provide a link that redirects to the app _if_ it&#39;s installed and to the store if not. Is this possible, and if so, how?

**Added for clarity**, the scenario is I&#39;m opening a link (http) from an e-mail on my iphone that&#39;s inviting me to join a group in an application. If the user has the app installed on that device it should open, otherwise the http link should redirect to itunes.

Redirect to application if installed, otherwise to App Store

I&#39;m going to make a native (meaning; *not* in the browser) mobile app. Since I&#39;m a web-developer I&#39;m struggling to decide whether or not I should try Phonegap or just build an native app in java or objective-c.

The app requirements are simple. GPS/wifi location, Facebook integration and I guess I&#39;ll need a database to handle some of the application specific Facebook-friend relations. Like the highscores in a game, for example - stuff like that.

I&#39;m a web-developer, and don&#39;t know neither java or objective-c, yet. I&#39;ve never used Phonegap before, so I don&#39;t know if it&#39;s capable of fulfilling my requirements.

So my question is as follows;
Can I use Phonegap for my app, or do I need to dive into a new language?

Struggling between native and phonegap, simple app requirements

I know this is not the perfect place to ask this question, but it is so hard to find a good answer and I prefer to ask experienced professionals.

What are the fees we must pay to publish an application on:

- Windows Store (for WP and W8)
- Google Play
- iTunes

And what is the percentage these companies keep?

What are the fees to develop on iOS, Android and WP?
