這里使用的是Runtime的黑魔法方法實現，靈感來源于CocoChina,在用網上搜到的方法運行不成功落包，死循環(huán)部蛇，廢話不多說上自己的代碼。
給UIControl建個分類
UIControl+FMGControl.h
#import <UIKit/UIKit.h>
@interface UIControl (FMGControl)
/** 按鈕點擊間隔*/
@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 延遲執(zhí)行 self.acceptEventInterval：為延遲時間
__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導入頭文件： UIControl+FMGControl.h
用到的地方多的話咐蝇，可以導入到pch 文件中
然后給按鈕設置個間隔時間 self.acceptEventInterval
同時不會影響到導航條上的按鈕
