iOS中关闭虚拟键盘的方法

 1.通过手势来关闭。

UITapGestureRecognizer *gesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(endEdit)];
[gesture setNumberOfTapsRequired:1];
[self.view addGestureRecognizer:gesture];
- (void)endEdit
{
[self.textFiled resignFirstResponder];
}

2.通过点击"return"按钮来退出
[self.textFiled addTarget:self action:@selector(endEdit:) forControlEvents:UIControlEventEditingDidEndOnExit];

- (void)endEdit:(id)sender
{
[sender resignFirstResponder];
}

第二种方式也可以通过storyboard连线做到，Did End and Exit 连线到

对应的控制器中。
