[英]Calling UIButton:setImage:forState makes button title disappear
If I call UIButton:setImage:forState
then the title text of my buttons is disappearing (set via UIButton:setTitle:forState
). 如果我调用UIButton:setImage:forState
则按钮的标题文本将消失(通过UIButton:setTitle:forState
)。
If I don't call setImage:forState
then the title appears perfectly. 如果我不调用setImage:forState
则标题会完美显示。
If I set the button images in interface builder then the title does appear, so why does setting the images programmatically cause the titel to vanish? 如果我在界面生成器中设置按钮图像,那么标题确实会出现,那么为什么以编程方式设置图像会导致标题消失?
而不是调用setImage:forState:
应该调用setBackgroundImage:forState:
