UIButton setImage：forState不使用64位架构

Question

I have existing project created a year ago. After AppStore's 64 bit requirement announcements, I had to include arm64 architecture into my project

But after adding arm64 into appTarget -> Build Settings -> Valid Architectures all the setImage: forState methods of all UIButton objects stopped working, while setBackGroundImage: forState is working normally.

UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, 20, 20)];
[button setImage:image forState:UIControlStateNormal];

To test this oddity I created new project and created UIButton and used setImage: forState method, everything is working as expected.

If I remove back arm64 architecture, every thing is ok with my project. I don't know what I did wrong with my project.

Answer 1

你应该使用UIControlState tydef而不是int [1]

[button setImage:image forState:UIControlStateNormal]
