UITextField弹出键盘挡住输入框问题

//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 convertRect:textField.frame toView:self.view];

  //上移数值,根据自己情况调整

    int offset = frame.origin.y - 100 - (UISCROEEN_SIZE.height - 216.0);//键盘高度216

    

    NSTimeInterval animationDuration = 0.30f;

    [UIView beginAnimations:@"ResizeForKeyboard" context:nil];

    [UIView setAnimationDuration:animationDuration];

    

    //将视图的Y坐标向上移动offset个单位,以使下面腾出地方用于软键盘的显示

    if(offset > 0)

        self.view.frame = CGRectMake(0.0f, -offset, UISCROEEN_SIZE.width, UISCROEEN_SIZE.height);

    

    [UIView commitAnimations];

}

//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, UISCROEEN_SIZE.width, UISCROEEN_SIZE.height);

}

- (BOOL)textFieldShouldReturn:(UITextField *)textField

{

    [textField resignFirstResponder];

    return YES;

}
