ios - 如何在 UIButton 中找出 UIControlStateNomal 和 UIControlStateSeleted

Question

UIButton 的方法 - (void)setImage:(UIImage *)image forState:(UIControlState)state。

因为如果您没有为 Selected 状态设置图像，那么当按钮被选中时，Normal 图像也会出现。

我的意思是我想为正常状态设置图像，并且只选择标题（无图像）？

对不起我的英语！

Answer 1

You call setImage:forState: as many times as you need:

[someButton setImage:someNormalImage forState:UIControlStateNormal];
[someButton setImage:someSelectedImage forState:UIControlStateSelected];

Update: It appears you want a button that shows just an image for the normal state and just a title for the selected state. I don't know if the following will work but give it a try:

[someButton setImage:someNormalImage forState:UIControlStateNormal];
[someButton setImage:nil forState:UIControlStateSelected];
[someButton setTitle:@"Some Title" forState:UIControlStateSelected];
