我们正在为iOS 7应用程序添加支持,以允许亚洲用户使用。然而,对于使用中文字符的键盘,if顶部有一个包含预测文本的滚动视图。一旦用户开始键入,水平滚动视图就会出现在键盘上方,并且永远不会消失。

有没有办法检测用户何时打开iOS 7中文字母键盘并打开预测?通过这种方式,我们可以将元素上移一点以补偿它。

想通了!首先收听UIKeyboardWillChangeFrameNotification。

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(changed:) name:UIKeyboardWillChangeFrameNotification object:nil];

通知将发送一个包含多个键盘参数的字典。UIKeyboardFrameEndUserInfoKey的高度将为您提供键盘高度的实时更新,包括来自亚洲键盘的预测。

- (void)changed:(NSNotification *)notification {
    NSDictionary *keyboardInfo = [notification userInfo];
    NSValue *keyboardFrameBegin = [keyboardInfo valueForKey:UIKeyboardFrameEndUserInfoKey];
    CGRect keyboardFrameBeginRect = [keyboardFrameBegin CGRectValue];
    float keyboardHeight = keyboardFrameBeginRect.size.height;
}
