content will be nil (which logs as &#39;(null)&#39;) if you pass it a path it can&#39;t open. So your only issue is that the relevant instance of NSBundle is unable to find test.txt within the resources part of your application bundle.

You should:

 1. check the file is in your Xcode project; and, if it is,
 2. check it&#39;s included in the &#39;Copy Bundle Resources&#39; phase underneath your selected Target (in the project tree view on the left in the normal Xcode window layout) and, if it is,
 3. look inside the generated application bundle (find your product, right click, select &#39;Reveal in Finder&#39;, from Finder right click on the app and select &#39;Show Package Contents&#39;, then look for your file in there) to make sure that it&#39;s there.

If it&#39;s copied in but the relevant instance of NSBundle can&#39;t find it then something very strange is afoot.

When my app runs (or when I run from commandline) the wkhtmltopdf command I get the following error: (showing it from command line)

I&#39;ve done this before, but its not working for me now. I&#39;m doing:

	NSString* path = [[NSBundle mainBundle] pathForResource:@&quot;test&quot;

	NSString* content = [NSString stringWithContentsOfFile:path
												  encoding:NSUTF8StringEncoding

	NSLog(@&quot;%@&quot;,path);

and it returns `(null)` every time when I NSLog path and content. Can anyone see what I&#39;m doing wrong?

I have a rectangle image (jpg) and want to use it to fill the background of a button with rounded corner in xcode.

I wrote the following:

	UIButton *button = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];
	CGRect frame = CGRectMake(x, y, cardWidth, cardHeight);
	button.frame = frame;
	[button setBackgroundImage:backImage forState:UIControlStateNormal];

However, the button I get with that approach doesn&#39;t have its corners rounded: it is instead a plain rectangle that looks exactly like my original image.  How can I get instead an image with rounded corner to represent my button?

Thanks!

I have a `UIView` called `baseView`and in that I have `initWithFrame`where I add some other views and do some custom stuff. The same view also has a NIB file.

Now I have a `UIViewController` class named `AppController` in which I want to add the `baseView` view to the view of the `AppController` view so I am doing this:

`self.view = baseView;` but the problem is that the NIB file does not get loaded. How do I make sure the customized stuff AND the NIB file get&#180;s loaded/run?

Basically, as the title says. I&#39;m wondering how I could add 1 day to an `NSDate`.

So if it were:

    21st February 2011

It would become:

    22nd February 2011

Or if it were:

    31st December 2011

It would become:

    1st January 2012.

I have created a screen using Objective-C in an iPhone project. In that, there are 2 buttons (say A and B). On the click of button A, one xml file will be created in a folder (say INBOX).

My problem is, I need to create the file only if it does not exist at folder INBOX.
How can I do this? Can any one tell me the syntax?

This one is quite specify: specify ttf font rendering `font-weight:bold` incorrectly on iOS mobile safari, open demo site with iphone/ipad with iOS 4.2/4.3 Beta 3 or above:

(this is Reenie+Beanie from google fonts)

http://jsbin.com/ojeqe3/16/

[Screen capture][1]

You see the bold font look **double rendered**. This is not significant for small and medium font size, but quite significant for large font-size / zoom in

My friend will report this bug to apple. However, anything he can do to solve the bug? (kill the text-adjust **is not** OK)

Update:
This one is **not fixed** in iOS5.

The best solution I know for the problem will be

1. Use `font-weight:normal` (as shown in demo)
2. Use either `-webkit-text-strok`e or `text-shadow` to make it look &quot;bold&quot; (plus iPad only css - body prefix added by js, not only media query)

I am working on a sketching app on the iPhone. 
I got it working but not pretty as seen here
![enter image description here][1]

And I am looking for any suggestion to smooth the drawing
Basically, what I did is when user places a finger on the screen I called

    - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 

then I collect a single touch in an array with 

    - (void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event

and when the user lefts a finger from the screen, I called

    - (void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event

then I draw all the points in the array using

    NSMutableArray *points = [collectedArray points];	
	
	CGPoint firstPoint;
	[[points objectAtIndex:0] getValue:&amp;firstPoint];
	
	CGContextMoveToPoint(context, firstPoint.x, firstPoint.y);
	CGContextSetLineCap(context, kCGLineCapRound);
	CGContextSetLineJoin(context, kCGLineJoinRound);
	
	for (int i=1; i &lt; [points count]; i++) {
		NSValue *value = [points objectAtIndex:i];
		CGPoint point;
		[value getValue:&amp;point];	
		CGContextAddLineToPoint(context, point.x, point.y);
		
	} 
	
	CGContextStrokePath(context);
	UIGraphicsPushContext(context);

And now I want to improve the drawing tobe more like &quot;Sketch Book&quot; App
![enter image description here][2]

I think there is something to do with signal processing algorithm to rearrange all the points in the array but I am not sure. Any Help would be much appreciated. 

Thankz in advance :)

Currently I&#39;m getting the selected text in the browser doing this:

    window.getSelection();

Now I need to show a tooltip above that text when pressing a custom key(note that the mouse could not be over the text anymore), so in order to do that I need the absolute position of that selected text.

Is there a way to do that, maybe wrapping that text inside a tag and then getting the offsets? It just has to work in Chrome, not all browsers.

I&#39;m using Python to open a text document:

    text_file.close()

I want to substitute the value of a string variable `TotalAmount` into the text document. Can someone please let me know how to do this?

There are already a number of questions about text rendering in OpenGL, such as:

* https://stackoverflow.com/questions/2071621/opengl-live-text-rendering

But mostly what is discussed is rendering textured quads using the fixed-function pipeline.  Surely shaders must make a better way.

I&#39;m not really concerned about internationalization, most of my strings will be plot tick labels (date and time or purely numeric).  But the plots will be re-rendered at the screen refresh rate and there could be quite a bit of text (not more than a few thousand glyphs on-screen, but enough that hardware accelerated layout would be nice).

What is the recommended approach for text-rendering using modern OpenGL?  (Citing existing software using the approach is good evidence that it works well)

* Geometry shaders that accept e.g. position and orientation and a character sequence and emit textured quads
* Geometry shaders that render vector fonts
* As above, but using tessellation shaders instead
* A compute shader to do font rasterization


What is state-of-the-art for text rendering in OpenGL as of version 4.1?

I&#39;m new to iPhone and Mac programming (developed for Windows before), and I&#39;ve got a question:

How do I animate the `text` property of an `UILabel` between two numbers, e.g. from **5** to **80** in an Ease-Out style? Is it possible with `CoreAnimation`?
I have been searching on Google for an hour, but I haven&#39;t found anything solving my problem.
What I want: Animate the users money for a simple game. It doesn&#39;t look very nice when it just goes from **50** to **100** or something like that without animation.

Anyone having an idea how to do that?

Thanks!

I have the following rectangle:

    &lt;rect x=&quot;0px&quot; y=&quot;0px&quot; width=&quot;60px&quot; height=&quot;20px&quot;/&gt;

I would like to center the word &quot;Fiction&quot; inside of it. For other rectangles, does SVG word wrap to stay within them? I can&#39;t seem to find anything specifically about inserting text within shapes that are centered both horizontally and vertically and word wrap. Also, the text can not leave the rectangle.

Looking at the https://www.w3.org/TR/SVG/text.html#TextElement example doesn&#39;t help since the text element&#39;s x and y are different from the rectangle&#39;s x and y. There doesn&#39;t seem to be width and height for text elements. I am not sure of the math here.

(My HTML table is just not going to work.)

As I understand, `Bundle` and `Parcelable` belongs to the way Android performs serialization in. It is used for example in passing data between activities. But I wonder, if there are any benefits in using `Parcelable` instead of classic serialization in case of saving state of my business objects to the internal memory for example? Will it be simpler or faster than the classic way? Where should I use classic serialization and where better to use bundles?

I have a Ruby script called foo.rb, and I want to run it within the context of the bundler environment. How?

`bundle exec foo.rb` doesn&#39;t work, because exec expects a shell script.

I have a Generic Map of Strings (Key, Value) and this field is part of a Bean which I need to be parcelable.
So, I could use the Parcel#writeMap Method. The API Doc says:

&gt; Please use writeBundle(Bundle) instead. Flattens a Map into the parcel
&gt; at the current dataPosition(), growing dataCapacity() if needed. The
&gt; Map keys must be String objects. The Map values are written using
&gt; writeValue(Object) and must follow the specification there. It is
&gt; strongly recommended to use writeBundle(Bundle) instead of this
&gt; method, since the Bundle class provides a type-safe API that allows
&gt; you to avoid mysterious type errors at the point of marshalling.


So, I could iterate over each Entry in my Map a put it into the Bundle, but I&#39;m still looking for a smarter way doing so. Is there any Method in the Android SDK I&#39;m missing?


At the moment I do it like this:

    final Bundle bundle = new Bundle();
    final Iterator&lt;Entry&lt;String, String&gt;&gt; iter = links.entrySet().iterator();
    while(iter.hasNext())
    {
        final Entry&lt;String, String&gt;  entry =iter.next();
        bundle.putString(entry.getKey(), entry.getValue());
    }
    parcel.writeBundle(bundle);

Is there any way to check if an extra has been passed when starting an Activity?

I would like to do something like (on the `onCreate()` in the Activity):

		Bundle extras = getIntent().getExtras();
		String extraStr = extras.getString(&quot;extra&quot;);
		
		if (extraStr == null) {
			extraStr = &quot;extra not set&quot;;
		}

But this is throwing a `java.lang.NullPointerException`.

Thank you.

I&#39;m trying to use MVC4 bundling to group some of my less files, but it looks like the import path I&#39;m using is off.  My directory structure is:

    static/
        less/
            mixins.less
            admin/
                user.less

In user.less, I&#39;m attempting to import mixins.less using this:

    @import &quot;../mixins.less&quot;;

This used to work for me before when using chirpy with dotless, but now I noticed ELMAH was getting mad at me, saying this:

    System.IO.FileNotFoundException: 
        You are importing a file ending in .less that cannot be found.
    File name: &#39;../mixins.less&#39;

Am I supposed to use a different `@import` with MVC4?

## Some additional info

Here&#39;s the less class and global.asax.cs code I&#39;m using to attempt this:

`LessMinify.cs`

    ...
    public class LessMinify : CssMinify
    {
        public LessMinify() {}

        public override void Process(BundleContext context, BundleResponse response)
        {
            response.Content = Less.Parse(response.Content);
            base.Process(context, response);
        }
    }
    ...

`Global.asax.cs`

    ...
    DynamicFolderBundle lessFB = 
        new DynamicFolderBundle(&quot;less&quot;, new LessMinify(), &quot;*.less&quot;);
        
    BundleTable.Bundles.Add(lessFB);

    Bundle AdminLess = new Bundle(&quot;~/AdminLessBundle&quot;, new LessMinify());
    ...
    AdminLess.AddFile(&quot;~/static/less/admin/user.less&quot;);
    BundleTable.Bundles.Add(AdminLess);
    ...
