- （空）的touchesBegan：（NSSet中*）触及withEvent：方法（*的UIEvent）事件{}不工作

Question

我调用的方法，

 - (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]; 

     } 

为目的的辞职第一responder.it工作正常没有使用scrollview.but如果我使用scrollview我无法使用此方法。为什么？

如果您需要使用滚动视图，则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]; 

}
