iOS键盘遮挡输入框

1）将输入框的代理设置为self

2）将输入框所对应的ViewController.h设置实现了UITextFieldDelegate协议

[cpp] view plaincopy

//开始编辑输入框的时候，软键盘出现，执行此事件

-(void)textFieldDidBeginEditing:(UITextField *)textField

{

CGRect frame = textField.frame;

int offset = frame.origin.y + 32 - (self.view.frame.size.height - 216.0);//键盘高度216

}

//当用户按下return键或者按回车键，keyboard消失

-(BOOL)textFieldShouldReturn:(UITextField *)textField

{

[textField resignFirstResponder];

return YES;

}

//输入框编辑完成以后，将视图恢复到原始状态

-(void)textFieldDidEndEditing:(UITextField *)textField

{

self.view.frame =CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);

}
