    CGPoint location = [self locationInView:self.view];
    
    //check actually view you hit via hitTest
    UIView *view = [self.view hitTest:location withEvent:event];
    
    if ([view.gestureRecognizers containsObject:self]) {
        currentViewBlock(self);
    } else {
        otherViewBlock(self);
    }
}

@end

#import "UIGestureRecognizer+EnvetInCurrentView.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    // 添加手势
    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self
                                                                          action:@selector(handleSingleTap:)];
    [self.view addGestureRecognizer:tap];
    
    UILabel *label      = [[UILabel alloc] initWithFrame:self.view.bounds];
    label.text          = @"Y.X. Touch Test";
    label.textAlignment = NSTextAlignmentCenter;
    label.font          = [UIFont fontWithName:@"HelveticaNeue-Thin" size:40.f];
    label.textColor     = [UIColor redColor];
    [self.view addSubview:label];
}

- (void)handleSingleTap:(UIGestureRecognizer *)gestureRecognizer
{
    [gestureRecognizer eventInCurrentView:^(UIGestureRecognizer *gesture) {
        NSLog(@"当前视图事件");
        // 显示
        [self.view showBackgroundViewAndConfig:^(BackgroundView *configView) {
            configView.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.6];
            configView.startDuration = 0.4f;
            configView.endDuration   = 0.4f;
        }];
        
        // 延迟3s执行
        [self performSelector:@selector(affterDelay)
                   withObject:nil
                   afterDelay:3.f];
    } inOtherView:^(UIGestureRecognizer *gesture) {
        NSLog(@"其他视图的事件");
    }];
}


- (void)affterDelay
{
    // 隐藏
    [self.view removeBackgroundView];
}

@end
