键盘覆盖面

退回输入键盘

  - (BOOL) textFieldShouldReturn:(id)textField{

    [textField  resignFirstResponder];

}

键盘覆盖输入框

当键盘调出时将输入框覆盖时，可以用下方法：

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField

{

[self.view setFrame:CGRectMake(0, -100, 375, 667) ];

return YES;

}

- (BOOL)textFieldShouldEndEditing:(UITextField *)textField

{

  [self.view setFrame:CGRectMake(0, 0, 375, 667)];

           return YES;

}

当准备输入时，将视图的位置上调100，这样键盘就不能覆盖到输入框。
