如何增加按钮的点击间隔时间

也是写一个分类

#import <UIKit/UIKit.h>

 

@interface UIControl (FMGControl)

@property (assign, nonatomic) NSTimeInterval   acceptEventInterval;

 

@end

 

 

---------------下面是.m文件---------------------

#import "UIControl+FMGControl.h"

#import <objc/runtime.h>

static const char *UIControl_acceptEventInterval = "UIControl_acceptEventInterval";

 

@implementation UIControl (FMGControl)

- (NSTimeInterval)acceptEventInterval

{

    return [objc_getAssociatedObject(self, UIControl_acceptEventInterval) doubleValue];

}

 

 

- (void)setAcceptEventInterval:(NSTimeInterval)acceptEventInterval

{

    objc_setAssociatedObject(self, UIControl_acceptEventInterval, @(acceptEventInterval), OBJC_ASSOCIATION_RETAIN_NONATOMIC);

}

 

- (BOOL)FMG_ignoreEvent

{

    return [objc_getAssociatedObject(self, UIControl_acceptEventInterval) doubleValue];

}

 

+ (void)load

{

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

    Method b = class_getInstanceMethod(self, @selector(FMG_sendAction:to:froEvent:));

    

    method_exchangeImplementations(a, b);

}

 

- (void)FMG_sendAction:(SEL)action to:(id)target froEvent:(UIEvent *)event

{

    if (self.acceptEventInterval > 0) {

        if (self.userInteractionEnabled) {

            

            [self FMG_sendAction:action to:target froEvent:event];

        }

        self.userInteractionEnabled = NO;

        

        [self performSelector:@selector(setUserInteractionEnabled:) withObject:@(YES) afterDelay:self.acceptEventInterval];

        

        

        // GCD 延迟执行 self.acceptEventInterval：为延迟时间

        __weak typeof (self) weakSelf = self;

        dispatch_time_t delayTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(self.acceptEventInterval * NSEC_PER_SEC));

        

        dispatch_after(delayTime, dispatch_get_main_queue(), ^{

            weakSelf.userInteractionEnabled = YES;

        });

        

        

        

    } else {

        [self FMG_sendAction:action to:target froEvent:event];

    }

    

}

 

@end

 

使用时：

　　

self.ViewButton.acceptEventInterval=5;//间隔5秒才能点击
