UIView没有接触

Question

- (void)viewDidLoad {
    checkingOption = [[UIView alloc] initWithFrame:CGRectMake(45, 250, 17, 15)];
checkingOption.backgroundColor = [UIColor grayColor];
checkingOption.layer.cornerRadius = 5;
checkingOption.layer.masksToBounds = YES;
    checkingOption.opaque = NO;
[self.view addSubview:checkingOption];
[checkingOption setUserInteractionEnabled:YES];
}

这是我在主视图上的新功能。现在我想测试一下，用户是否接触到了...

-(void)touchesBegan: (NSSet *)touches withEvent:(UIEvent *)event{

[self.usernameField resignFirstResponder];
[self.passwordField resignFirstResponder];
UITouch *touch =[touches anyObject]; 
CGPoint startPoint =[touch locationInView:checkingOption];
if(CGRectContainsPoint(checkingOption.frame,startPoint)){

    NSLog(@"touch inside the checking view");

}

请帮帮我..我找不到问题。

先谢谢。

将UITapGestureRecognizer添加到您的视图

UITapGestureRecognizer *singleTapOne = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];
    singleTapOne.numberOfTouchesRequired = 1; singleTapOne.numberOfTapsRequired = 1; singleTapOne.delegate = self;
[self.view addGestureRecognizer:singleTapOne]; [singleTapOne release];
- (void)handleSingleTap:(UITapGestureRecognizer *)recognizer
{
}
