ios – 选择一个UIButtons时取消选择

解决方法

// UnSELEct all the buttons in the parent view
for (UIView *button in currentButton.superview.subviews) {
    if ([button isKindOfClass:[UIButton class]]) {
        [(UIButton *)button setSELEcted:NO];
    }
}

// Set the current button as the only SELEcted one
[currentButton setSELEcted:YES];

注意：正如评论中所建议的那样,您可以保留一组按钮,并按照上述代码与父视图的子视图相同的方式进行检查.如果包含按钮的视图中包含许多其他子视图,这将提高代码的性能.
