iOS 点击图片的坐标响应对应的事件

1、不规则形状

- (void)viewDidLoad {
    [super viewDidLoad];
    
    UITapGestureRecognizer *tap=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapClick:)];
    [self.mapImageView addGestureRecognizer:tap];
  
    self.scaleW=ScreenWidth/375;
    self.scaleH=ScreenHeight/667;
}

-(UIBezierPath *)path1H{
    if (_path1H==nil) {
        _path1H=[[UIBezierPath alloc] init];
        [_path1H moveToPoint:CGPointMake(303*self.scaleW,222*self.scaleH)];
        [_path1H addLineToPoint:CGPointMake(335.5*self.scaleW, 249*self.scaleH)];
        [_path1H addLineToPoint:CGPointMake(274*self.scaleW, 316.5*self.scaleH)];
        [_path1H addLineToPoint:CGPointMake(242.5*self.scaleW, 318*self.scaleH)];
        [_path1H addLineToPoint:CGPointMake(228*self.scaleW, 303*self.scaleH)];
        [_path1H closePath];
        
    }
    return _path1H;
}

-(void)tapClick:(UITapGestureRecognizer *)tapGesture{
    CGPoint point=[tapGesture locationInView:self.mapImageView];
    if ([self.path1H containsPoint:point]) {
         NSLog(@"测试坐标点path1H%f---%f",point.x,point.y);
    }

}

2、矩形

bool CGRectContainsPoint(CGRect rect,CGPoint point)
bool CGRectContainsRect(CGRect rect1, CGRect rect2)
