我有一个设置放置故事板的UIButton的imageView属性的方法。它设置后,它看起来很好。但是,轻触按钮时,其高亮状态会将imageView的图像属性更改回旧图像。我如何阻止这种情况发生?这里是我的方法:如何在按下时阻止UIButton的imageView更改?
- (void)setThumbButtonPhoto:(UIImage *)image
{
// profilePhoto is an IBOutlet property of class UIButton pointing to the
// UIButton on my storyboard.
// Button image is changed correctly here
profilePhoto.imageView.image = image;
// But then mysteriously changed back to the old image when tapped.
// The following commented out lines I have all tried (one at a time of course)
// and none have solved my problem -->
// [profilePhoto.imageView setHighlightedImage:nil];
// profilePhoto.imageView.highlightedImage = image;
// profilePhoto.adjustsImageWhenHighlighted = NO;
// [profilePhoto setBackgroundImage:image forState:UIControlStateHighlighted];
// [profilePhoto setImage:image forState:UIControlStateNormal];
// [profilePhoto setImage:image forState:UIControlStateHighlighted];
// [profilePhoto setImage:image forState:UIControlStateSelected];
}
取消注释所有这三个线 // [profilePhoto setImage的:图像forState :UIControlStateNormal]; // [profilePhoto setImage:image forState:UIControlStateHighlighted]; // [profilePhoto setImage:image forState:UIControlStateSelected]; 在一起运行,并告诉我发生了什么 –
它改变了按钮的背景图像,而不是像我想要的内部imageView图像。 – zakdances
