1. Swift 解决方案 ```swift // // UIButtonExtension.swift // GrandJustice // // Created by Alfred Jiang on 1/29/15. // Copyright (c) 2015 FYH. All rights reserved. //

import Foundation

extension UIButton { func antiMultiplyTouch(delay : NSTimeInterval, closure:()->()) { self.userInteractionEnabled = false

        dispatch_after(
            dispatch_time(
                DISPATCH_TIME_NOW,
                Int64(delay * Double(NSEC_PER_SEC))
            ),
            dispatch_get_main_queue(), {
                self.userInteractionEnabled = true
                closure()
        })
}

}

2. Objective-C 解决方案
```objective-c

//
//  UIButton+AntiMultiplyTouch.h
//  TestButton

#import <UIKit/UIKit.h>

@interface UIButton (antiMultiplyTouch)

- (void)antiMultiplyTouch:(NSTimeInterval)delay block:(void(^)(void))operation;

@end

== .m文件
#import "UIButton+AntiMultiplyTouch.h"

@implementation UIButton (AntiMultiplyTouch)

- (void)antiMultiplyTouch:(NSTimeInterval)delay block:(void(^)(void))operation
{
    self.userInteractionEnabled = NO;

    dispatch_after(
                   dispatch_time(
                                 DISPATCH_TIME_NOW,
                                 delay * NSEC_PER_SEC
                                 ),
                   dispatch_get_main_queue(),
                   ^{
                        self.userInteractionEnabled = YES;
                        operation();
                    }
                   );
}
