当键盘出现在 iOS 中时，将 UIView 上移

发布于07月01日

我有一个UIView，它不在UIScrollView中.当键盘出现时，我想要上移我的视图.在我try 使用这个解决方案之前:How can I make a UITextField move up when the keyboard is present?.

它工作得很好.但在文本字段中插入数据后，它会将我带到另一个视图，当我回到这个页面时，它只是跳转，我看不到我的文本字段.这个问题有更好的解决方案吗？

推荐答案

使用以下代码来显示和隐藏键盘

//Declare a delegate, assign your textField to the delegate and then include these methods

-(BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidShow:) name:UIKeyboardDidShowNotification object:nil];
    return YES;
}


- (BOOL)textFieldShouldEndEditing:(UITextField *)textField {
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardDidHide:) name:UIKeyboardDidHideNotification object:nil];

    [self.view endEditing:YES];
    return YES;
}


- (void)keyboardDidShow:(NSNotification *)notification
{
    // Assign new frame to your view 
    [self.view setFrame:CGRectMake(0,-110,320,460)]; //here taken -110 for example i.e. your view will be scrolled to -110. change its value according to your requirement.

}

-(void)keyboardDidHide:(NSNotification *)notification
{
    [self.view setFrame:CGRectMake(0,0,320,460)];
}
