Setting constraints in empty ViewController xcode 5

Question

I have an empty ViewController. Programatically I'm setting back ground image.

- (void)setBackGroundImg:(NSString*) name {

    UIGraphicsBeginImageContext(self.view.frame.size);
    [[UIImage imageNamed:name] drawInRect:self.view.bounds];
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    self.view.backgroundColor = [UIColor colorWithPatternImage:image];

}

Problem: I'm running app in simulator. Without rotation its looks like this. enter image description here

But when I rotate the simulator app looks like this enter image description here

Any idea how can i fix this issue.I'm working on Xcode 5 with auto layout ON. I see no way how to set constraints in empty ViewController

Pattern image will replicate itself. What are you trying to achieve? Maybe it can be done in other way. — vokilam, Feb 10 '14 at 10:12
and is this possible when i rotate the simulator image also rotate it self? — Omer Obaid, Feb 10 '14 at 10:21
@vokilam you can see in picture, image not rotating when simulator rotate — Omer Obaid, Feb 10 '14 at 10:26
you can allow portrait orientation only in tagret settings (general tab) — vokilam, Feb 10 '14 at 10:30
It won't rotate itself, you have to programmatically rotate the image. — Praveen Matanam, Feb 10 '14 at 10:31
I think `CGContextRotateCTM(CGContextRef c, CGFloat angle)` will work. Reset background after orientation change. — vokilam, Feb 10 '14 at 10:55

If you want an image to rotate automatically when the device rotates, display the image inside a UIImageView instead of drawing the image manually. Check the docs for UIImageView.

just use 9-path, for example:

self.view.backgroundColor = [UIColor colorWithPatternImage:[image resizableImageWithCapInsets:UIEdgeInsetsMake(10, 10, 10, 10)]];
