写一个UIButton的分类:
当点击之后1.5秒方能再次点击响应点击事件
#import "UIButton+Event.h"
@implementation UIButton (Event)
/** 重写父类方法*/
- (void)sendAction:(SEL)action to:(id)target forEvent:(UIEvent *)event{
// 响应父类方法
[super sendAction:action to:target forEvent:event];
// 设置按钮属性不能相应事件
[self setUserInteractionEnabled:false];
// GCD 延时执行
dispatch_time_t delayTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.5/*延迟执行时间*/ * NSEC_PER_SEC));
dispatch_after(delayTime, dispatch_get_main_queue(), ^{
// 设置按钮属性能相应事件
[self setUserInteractionEnabled:true];
});
}
@end
