【问题描述】：

我调用了方法，

     - (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];

      }

出于辞职第一响应者的目的。它在不使用滚动视图的情况下正常工作。但是如果我使用滚动视图，我无法使用此方法。为什么？

【解决方案1】：

如果您需要使用滚动视图，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];

 }
