UIButton 事件監控和連點

1、button點擊事件監測

通過runtime獲取button的點擊事件，進行全局監測

#import "UIControl+XHControl.h"
#import <objc/runtime.h>

@implementation UIControl (XHControl)

+ (void)load
{
    Method m1 = class_getInstanceMethod([self class], @selector(sendAction:to:forEvent:));
    Method m2 = class_getInstanceMethod([self class], @selector(xh_sendAction:to:forEvent:));
    
   BOOL addSuccess = class_addMethod([self class], @selector(sendAction:to:forEvent:), method_getImplementation(m2), method_getTypeEncoding(m2));
    
    if (!addSuccess) {
        method_exchangeImplementations(m1, m2);
    }
}


- (void)xh_sendAction:(SEL)action to:(id)target forEvent:(UIEvent *)event
{    
    [self xh_sendAction:action to:target forEvent:event];
}

2、button多次點擊

• 設置button.enable屬性進行管理

• 通過runtime，監控點擊方法，添加時間屬性進行管理

#import <UIKit/UIKit.h>

NS_ASSUME_NONNULL_BEGIN

@interface UIControl (XHControl)

/***/
@property (nonatomic,strong) NSDate *currentDate;

@end

NS_ASSUME_NONNULL_END

#import "UIControl+XHControl.h"
#import <objc/runtime.h>

NSTimeInterval const delayInterval = 1;
static const char *delayConst = 0;

@implementation UIControl (XHControl)

- (void)setCurrentDate:(NSDate *)currentDate
{
    objc_setAssociatedObject(self, &delayConst, currentDate, OBJC_ASSOCIATION_COPY_NONATOMIC);
}

- (NSDate *)currentDate{
    return objc_getAssociatedObject(self, &delayConst);
}



+ (void)load
{
    Method m1 = class_getInstanceMethod([self class], @selector(sendAction:to:forEvent:));
    Method m2 = class_getInstanceMethod([self class], @selector(xh_sendAction:to:forEvent:));
    
    BOOL addSuccess = class_addMethod([self class], @selector(xh_sendAction:to:forEvent:), method_getImplementation(m2), method_getTypeEncoding(m2));
    
    if (addSuccess) {
        method_exchangeImplementations(m1, m2);
    }
}


- (void)xh_sendAction:(SEL)action to:(id)target forEvent:(UIEvent *)event
{
    if ([[NSDate date] timeIntervalSinceDate: self.currentDate] <= delayInterval) {
    //這裏的delayInterval也可以通過添加一個屬性變量進行傳值
        return;
    }
    
    self.currentDate = [NSDate date];
    
    NSLog(@"234");
    
    [self xh_sendAction:action to:target forEvent:event];
}

@end
