Images not showing up when architecture set to 64 bit

Question

For transitioning my app to 64-bit, I changed the Architectures build setting to:

ARCHS = "$(ARCHS_STANDARD_INCLUDING_64_BIT)";

App is runnig fine except that some of the images are not showing up (blank). Why would it happen? any clues?

I found the reason. In a viewController, which was not yet allocated, but included in the app, there was following implemented (in the .m-file above implementation viewController):

@implementation UIImageView (UIScrollView)
- (void)setAlpha:(float)alpha {
..........(no difference if here is some code or not) ...............
  [super setAlpha:alpha];
}
@end

Putting above in comment solved the problem, even though the button which didn't display the image wasn't in a scrollview.
