当键盘出现在iOS中时，向上移动UIView [英] Move UIView up when the keyboard appears in iOS

问题描述

我有一个UIView，它不在UIScrollView中。我想在键盘出现时向上移动我的视图。在我尝试使用此解决方案之前：如何当键盘出现时，我让UITextField向上移动？。

I have a UIView, it is not inside UIScrollView. I would like to move up my View when the keyboard appears. Before I tried to use this solution: How can I make a UITextField move up when the keyboard is present?.

它工作正常。但是在文本字段中插入数据后，它会转到另一个视图，当我回到这个页面时，它只是跳跃，我看不到我的文本字段。有没有更好的解决方案来解决这个问题？

It was working fine. But after inserting the data in the textfields, it takes me to another view, and when I get back to this page, its just jumping, and I couldn't see my text fields. Is there any better solution for this problem?

推荐答案

使用以下代码显示和隐藏键盘

Use the following code in order to show and hide the keyboard

//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)];
}
