uiimage - Setting UIButton image results in blue button in iOS 7

Question

On iOS 6 SDK I wrote the following lines of code to display an image inside a button:

NSURL *thumbURL2 = [NSURL URLWithString:@"http://example.com/thumbs/2.jpg"];
NSData *thumbData2 = [NSData dataWithContentsOfURL:thumbURL2];
UIImage *thumb2 = [UIImage imageWithData:thumbData2];
[btn2 setImage:thumb2 forState:UIControlStateNormal];
[self.view addSubview:btn2];

But now with Xcode 5 and iOS 7 this doesn't work. The button doesn't contain the image. The button is filled with blue color.

Answer 1

In iOS7 there is new button type called UIButtonTypeSystem NS_ENUM_AVAILABLE_IOS(7_0), // standard system button

Check your .xib file and change button type to Custom

To do this programmatically, add this line to the viewDidLoad:

[UIButton buttonWithType:UIButtonTypeSystem];
