这里使用的是Runtime的黑魔法方法实现，灵感来源于CocoChina,在用网上搜到的方法运行不成功，死循环，废话不多说上自己的代码。
给UIControl建个分类
UIControl+FMGControl.h
#import <UIKit/UIKit.h>
@interface UIControl (FMGControl)
/** 按钮点击间隔*/
@property (assign, nonatomic) NSTimeInterval acceptEventInterval;
@end
UIControl+FMGControl.m
#import "UIControl+FMGControl.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：
在你需要用到的地方导入头文件： UIControl+FMGControl.h
用到的地方多的话，可以导入到pch 文件中
然后给按钮设置个间隔时间 self.acceptEventInterval
同时不会影响到导航条上的按钮
