防止点击事件重复点击的方法

一：

#import

@interfaceUIButton (CS_FixMultiClick)

@property(nonatomic,assign)NSTimeIntervalcs_acceptEventInterval;// 重复点击的间隔

@property(nonatomic,assign)NSTimeIntervalcs_acceptEventTime;

@end

#import "UIButton+CS_FixMultiClick.h"

#import

@implementationUIButton (CS_FixMultiClick)

// 因category不能添加属性，只能通过关联对象的方式。

staticconstchar*UIControl_acceptEventInterval ="UIControl_acceptEventInterval";

- (NSTimeInterval)cs_acceptEventInterval {

//    return  [objc_getAssociatedObject(self, UIControl_acceptEventInterval) doubleValue];

    return 1;

}

- (void)setCs_acceptEventInterval:(NSTimeInterval)cs_acceptEventInterval {

    objc_setAssociatedObject(self, UIControl_acceptEventInterval, @(cs_acceptEventInterval), OBJC_ASSOCIATION_ASSIGN);

}

staticconstchar*UIControl_acceptEventTime ="UIControl_acceptEventTime";

- (NSTimeInterval)cs_acceptEventTime {

    return  [objc_getAssociatedObject(self, UIControl_acceptEventTime) doubleValue];

}

- (void)setCs_acceptEventTime:(NSTimeInterval)cs_acceptEventTime {

    objc_setAssociatedObject(self, UIControl_acceptEventTime, @(cs_acceptEventTime), OBJC_ASSOCIATION_ASSIGN);

}

// 在load时执行hook

+ (void)load {

    Methodbefore  =class_getInstanceMethod(self,@selector(sendAction:to:forEvent:));

    Methodafter    =class_getInstanceMethod(self,@selector(cs_sendAction:to:forEvent:));

    method_exchangeImplementations(before, after);

}

- (void)cs_sendAction:(SEL)action to:(id)target forEvent:(UIEvent*)event {

    if ([NSDate date].timeIntervalSince1970 - self.cs_acceptEventTime < self.cs_acceptEventInterval) {

        return;

    }

    if (self.cs_acceptEventInterval > 0) {

        self.cs_acceptEventTime = [NSDate date].timeIntervalSince1970;

    }

    [selfcs_sendAction:actionto:targetforEvent:event];

}

@end

第二种：

- (IBAction)buttonActions:(UIButton*)sender{

sender.enable = NO;

   dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

            sender.enabled=YES;

        });

}

第三种 ，在button点击事件中写这个

[[selfclass]cancelPreviousPerformRequestsWithTarget:selfselector:@selector(buttonClicked:)object:sender];

  [selfperformSelector:@selector(buttonClicked: )withObject:senderafterDelay:0.2f];
