如何在iOS 7上使用UITextView添加对中文键盘的支持？ [英] How can I add support for Chinese keyboard with UITextView on iOS 7?

问题描述

如何在 iOS 7 上添加 UITextView 的中文键盘支持？目前我正在使用以下代码。但它只适用于标准尺寸的键盘。它只为主键盘调整 UITextView 的大小而没有额外的中文面板。

How can I add support for Chinese keyboard with UITextView on iOS 7? Currently I'm using the following code. But it works correctly only for standard-sized keyboards. It resizes UITextView only for the main keyboard without additional Chinese panel.

bool keyboardIsShown;
float keyboardDelta;

- (void)keyboardWillShow:(NSNotification*)aNotification {
    if (!keyboardIsShown) {
        keyboardIsShown = true;
        NSDictionary* userInfo = [aNotification userInfo];
        CGSize keyboardSize = [[userInfo objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
        if (is_Landscape) {
            keyboardSize = CGSizeMake(keyboardSize.height, keyboardSize.width);
        }
        keyboardSize.height -= tabBarController.tabBar.frame.size.height;
        CGRect viewFrame = myUITextView.frame;
        keyboardDelta = keyboardSize.height;
        viewFrame.size.height -= keyboardDelta;

        NSTimeInterval animationDuration;
        UIViewAnimationCurve animationCurve;
        [[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
        [[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];
        [UIView beginAnimations:nil context:NULL];
        [UIView setAnimationCurve:animationCurve];
        [UIView setAnimationDuration:animationDuration];
        [myUITextView setFrame:viewFrame];
        [UIView commitAnimations];
    }
}

- (void)keyboardWillHide:(NSNotification*)aNotification {
    keyboardIsShown = false;
    CGRect viewFrame = editor.frame;
    viewFrame.size.height += keyboardDelta;

    NSDictionary* userInfo = [aNotification userInfo];
    NSTimeInterval animationDuration;
    UIViewAnimationCurve animationCurve;
    [[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
    [[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationCurve:animationCurve];
    [UIView setAnimationDuration:animationDuration];
    [myUITextView setFrame:viewFrame];
    [UIView commitAnimations];
}

感谢 jcaron 即可。正确的代码：

Thanks to jcaron. The correct code:

bool keyboardIsShown;
float editorHeight;

- (void)keyboardWillShow:(NSNotification*)aNotification {
    NSDictionary* userInfo = [aNotification userInfo];
    CGSize keyboardSize = [[userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size;
    if (is_Landscape) {
        keyboardSize = CGSizeMake(keyboardSize.height, keyboardSize.width);
    }
    keyboardSize.height -= tabBarController.tabBar.frame.size.height;
    CGRect viewFrame = editor.frame;
    if (!keyboardIsShown) {
        editorHeight = viewFrame.size.height;
    }
    viewFrame.size.height = editorHeight - keyboardSize.height;
    keyboardIsShown = true;

    NSTimeInterval animationDuration;
    UIViewAnimationCurve animationCurve;
    [[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
    [[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationCurve:animationCurve];
    [UIView setAnimationDuration:animationDuration];
    [editor setFrame:viewFrame];
    [UIView commitAnimations];
}

- (void)keyboardWillHide:(NSNotification*)aNotification {
    keyboardIsShown = false;
    CGRect viewFrame = editor.frame;
    viewFrame.size.height = editorHeight;

    NSDictionary* userInfo = [aNotification userInfo];
    NSTimeInterval animationDuration;
    UIViewAnimationCurve animationCurve;
    [[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
    [[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationCurve:animationCurve];
    [UIView setAnimationDuration:animationDuration];
    [editor setFrame:viewFrame];
    [UIView commitAnimations];
}
