步驟1.viewDidLoad{}方法中設(shè)置監(jiān)聽

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(revertViewBounds) name:UIKeyboardWillHideNotification object:nil];

步驟2.在.m中添加此方法，此時(shí)已經(jīng)設(shè)置結(jié)束編輯時(shí)（收起鍵盤時(shí)頁(yè)面位置）

- (void)revertViewBounds
{
    if (self.view.bounds.origin.y > 0)
    {
        [UIView animateWithDuration:0.2 animations:^{
            self.view.bounds = CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height);
        }];
    }
}

步驟3.設(shè)置開始編輯時(shí)頁(yè)面位置

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{　
    //可以在此處設(shè)置彈出鍵盤時(shí)頁(yè)面布局
    CGRect newTFRect = [textField convertRect:textField.bounds toView:self.view];
    CGFloat dist = (ScreenHeight - 216) - (newTFRect.origin.y + newTFRect.size.height + 100);

    if (dist < 0) {
        [UIView animateWithDuration:0.3 animations:^{
            self.view.bounds = CGRectMake(0, -dist, self.view.bounds.size.width, self.view.bounds.size.height);
        }];
    }

    return YES;
}
