不推荐使用UIKeyboardBoundsUserInfoKey，而是使用什么？ [英] UIKeyboardBoundsUserInfoKey is deprecated, what to use instead?

问题描述

我正在使用3.2 sdk开发iPad应用程序。我正在处理获取键盘大小以防止我的文本字段隐藏在它后面。

I'm working on an iPad app using 3.2 sdk. I'm dealing with obtaining the keyboard size to prevent my textfields from hidding behind it.

我在Xcode中收到警告 - > UIKeyboardBoundsUserInfoKey已被弃用我应该使用什么而不是获取此警告？

I'm getting a Warning in Xcode -> UIKeyboardBoundsUserInfoKey is deprecated what should I use instead not to get this warning?

推荐答案

我使用之前提供的解决方案，但仍有问题。以下是我提出的内容：

I played with the previously offered solution but still had issues. Here's what I came up with instead:

    - (void)keyboardWillShow:(NSNotification *)aNotification {
    [self moveTextViewForKeyboard:aNotification up:YES];
}

    - (void)keyboardWillHide:(NSNotification *)aNotification {
        [self moveTextViewForKeyboard:aNotification up:NO]; 
    }

- (void) moveTextViewForKeyboard:(NSNotification*)aNotification up: (BOOL) up{
NSDictionary* userInfo = [aNotification userInfo];

// Get animation info from userInfo
NSTimeInterval animationDuration;
UIViewAnimationCurve animationCurve;

CGRect keyboardEndFrame;

[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];


[[userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] getValue:&keyboardEndFrame];


// Animate up or down
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:animationDuration];
[UIView setAnimationCurve:animationCurve];

CGRect newFrame = textView.frame;
CGRect keyboardFrame = [self.view convertRect:keyboardEndFrame toView:nil];

newFrame.origin.y -= keyboardFrame.size.height * (up? 1 : -1);
textView.frame = newFrame;

[UIView commitAnimations];
}
