i made an UIButton with image and text using storyboard. which has center X and Y constraints in UIViewController.view(that's all. my UIViewController just has one UIButton.)then run my app, it looks fine.but When setting "Bold Text" (under iOS Settings, General, Accessibility), my button trimmed text.i didn't use any custom font. just set an image size 20*20 and text (e.g hello)is this known issue or am i missing something??
