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?
Answer lies here:

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.
Update the Data structure used in code according to 64 bits for example replace Float
with CGFloat
,(if not working Than also change int
type with NSInteger
)
see here for more information
In my case replace Float
with CGFloat
and solve my problem (simplest way to replace float
to CGFloat
)
#define float CGFloat
Write in .pch file and check it working or not.
Thanks
It fixed my issue to change
- (void)setAlpha:(float)alpha {
to:
- (void) setAlpha:(CGFloat)alpha {
