Add this line of code on your application delegate:

Objective-C:

    [[UIApplication sharedApplication] setIdleTimerDisabled:YES];

Swift 2:

    UIApplication.sharedApplication().idleTimerDisabled = true

Swift 3, 4 &amp; 5:

    UIApplication.shared.isIdleTimerDisabled = true

I have a service class. I have exported this class to jar and I have embed the jar in my client app.

When needed, I call the service class. When I try to do this, I get the following error:

    Unable to start service Intent {comp={com.sample.service/com.sample.service.serviceClass}} : not found

I have other class apart from the service class, which I am able to access (create object of that class) which are inside the same jar.

I feel I have missed out some thing in my configuration or manifest or so.

Please help me identifying the same. My code is below:

    public void onCreate(Bundle savedInstanceState) {    
          super.onCreate(savedInstanceState);  
          Intent intent = new Intent () ;  
          intent.setClassName(&quot;com.sample.service&quot; ,&quot;com.sample.service.serviceClass&quot;) ;  
          this.startService(intent) ; // when I call this line I get the message...  
          // binding other process continue  here   
    }

Client manifest.xml

    &lt;service android:name=&quot;com.sample.service.serviceClass&quot;  
                android:exported=&quot;true&quot; android:label=&quot;@string/app_name&quot; 
                android:process=&quot;:remote&quot;&gt;
       &lt;intent-filter&gt;&lt;action android:name=&quot;com.sample.service.serviceClass&quot;&gt;&lt;/action&gt;
       &lt;/intent-filter&gt;
    &lt;/service&gt;


Thanks in advance,

In Java, you can do `instanceof`. Is there a Ruby equivalent?

I&#39;m diving into iOS development and am building my own alarm clock app to become familiar with platform and SDK. I&#39;ve noticed some alarm clock apps in the app store keep the screen from dimming and/or turning off when their app is running. How is this implemented?

I&#39;m new to the iPhone submission process. Apple asks for the Bundle ID Suffix. What is this? Not sure what to put here and what the significance of it is.

Bundle ID Suffix? What is it?


Bundle Name, Executable Name, Product Name... any more??

can someone please help clarify the use of each of these in Xcode on an iPhone project?  They never fail to confuse the living bajezus out of me...and Im tired of getting them wrong.

Someone please explain... why the hell do we need this many different naming schemes for one app environment? and what do I use each of these for so I can stick them in the right cubby hole in my head?

I have a couple UIButtons, and in IB they&#39;re set to Aspect Fit, but for some reason they&#39;re always stretching.  Is there something else you have to set?  I tried all the different view modes and none of them work, they all stretch.

I may be doing something really stupid here as I&#39;ve done it before and it worked and now...

Created a new iPad project, in the details view I added a MKMapView, added the MapKit.framework to the project, added the property / etc. to the header.  Go to run the project and get a SIGABRT with 

&gt; ****Terminating app due to uncaught exception &#39;NSInvalidUnarchiveOperationException&#39;, reason: &#39;Could not instantiate
&gt; class named MKMapView&#39;**

I found http://mithin.in/2009/06/22/using-iphone-sdk-mapkit-framework-a-tutorial/ but, like I said, I&#39;ve already added framework.  What am I missing?

Could not instantiate class named MKMapView

I have a `UIScrollView` decendent that implements a takeScreenshot method that looks like this:


    -(void)takeScreenshot {  
      CGRect contextRect  = CGRectMake(0, 0, 768, 1004);
      UIGraphicsBeginImageContext(contextRect.size);	
      [self.layer renderInContext:UIGraphicsGetCurrentContext()];
      UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
      UIGraphicsEndImageContext();
      
      // do something with the viewImage here.
    }

This basically moves to the top of the scroll view, and takes a screenshot of the visible area. It works fine when the iPad is oriented portrait, but when it&#39;s in landscape the bottom of the image is cut off (as the height of the visible area is only 748, not 1004).

Is it possible to get a snapshot of the `UIScrollView`, including areas not on screen? Or do I need to scroll the view down, take a second photo and stitch them together?

Hi I&#39;m wondering if there&#39;s a way to get the width programmatically. 

I&#39;m looking for something general enough to accomodate iphone 3gs, iphone 4, ipad. Also, the width should change based on if the device is portrait or landscape (for ipad).

Anybody know how to do this?? I&#39;ve been looking for a while... thanks!

I need a way to center the current window. So for example, if a user pushes a button, I want the window to center itself onscreen. I know you can use the startposition property, but I cannot figure out a way to use that other than when the application first starts up. So how do I center the form on the screen?

I&#39;m trying to force the &quot;portrait&quot; mode for my application because my application is absolutely not designed for the &quot;landscape&quot; mode.

After reading some forums, I added these lines in my manifest file:

    &lt;application 
      android:debuggable=&quot;true&quot;
      android:icon=&quot;@drawable/icon&quot; 
      android:label=&quot;@string/app_name&quot;
      android:screenOrientation=&quot;portrait&quot;&gt;

But it doesn&#39;t work on my device (HTC Desire). It switches from &quot;portrait&quot; lo &quot;landscape&quot;, ignoring the lines from the manifest file.

After more forums reading, I tried to add this in my manifest file:

    &lt;application 
      android:debuggable=&quot;true&quot;
      android:icon=&quot;@drawable/icon&quot; 
      android:label=&quot;@string/app_name&quot;
      android:configChanges=&quot;orientation&quot;    	
      android:screenOrientation=&quot;portrait&quot;&gt;

and this function in my activity class:

    public void onConfigurationChanged(Configuration newConfig)
    {
        super.onConfigurationChanged(newConfig);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }

But again, no luck.

I have a URL in an iPhone application to work with. But the problem is that it has some spaces in the URL. I want to replace the spaces with &#39;%20&#39;. I know that there are the `stringByReplacingOccurencesOfString` and `stringByAddingPercentEscapesUsingEncoding` methods. I also have used them. But they are not working for me. The spaces are replaced by some unusual values.

I&#39;m applying those methods on an instance of `NSString`.

I want to remove my app, which is currently marked &quot;Ready for sale&quot;, from the App Store.

I&#39;m looking to set the left inset/margin of a `UILabel` and can&#39;t find a method to do so. The label has a background set so just changing its origin won&#39;t do the trick. It would be ideal to inset the text by `10px` or so on the left hand side.
