- （void）touchesBegan：（NSSet *）触及withEvent：（UIEvent *）event {}不起作用

Question

我打电话给方法，

     - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [super touchesBegan:touches withEvent:event];
    [self.name resignFirstResponder];
    [self.userName resignFirstResponder];
    [self.mailId resignFirstResponder];
    [self.password resignFirstResponder];
    [self.reTypePassword resignFirstResponder];

      }

为了辞职第一个responder.it工作正常而不使用scrollview.but如果我使用scrollview我不能使用此方法。为什么？

Answer 1

如果需要使用滚动视图，可以添加手势识别器。 试试这个：

UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(resignFirstResponder:)];
 gestureRecognizer.delegate = self;
 [scrollView addGestureRecognizer:gestureRecognizer];


-(void) resignFirstResponder:(UITapGestureRecognizer *) gesture
 {
    [self.name resignFirstResponder];
    [self.userName resignFirstResponder];
    [self.mailId resignFirstResponder];
    [self.password resignFirstResponder];
    [self.reTypePassword resignFirstResponder];

 }
