I'm building a iOS 8 custom keyboard and I'd like the change the layout of the keyboard based on the UIKeyboardType, however, reading the keyboard type in UIInputViewController is always 0. Any suggestions? Thanks in advance!

- (void)viewDidLoad
{
    [super viewDidLoad];

    NSLog(@"TextInputMode: %ld", self.textDocumentProxy.keyboardType);
}

推荐答案

获取 keyboardType 在InputView Delegate方法而不是ViewDidLoad中。因为在键盘完全呈现并且输入对象被激活之前你无法获得keyboardType。

Get the keyboardType in InputView Delegate Methods Instead of ViewDidLoad . Because you can't get the keyboardType until The keyboard is fully presented and the input object is activated .

- (void)textWillChange:(id<UITextInput>)textInput {

    NSLog(@"TextInputMode: %ld", self.textDocumentProxy.keyboardType);

}

OR

- (void)textDidChange:(id<UITextInput>)textInput {

    NSLog(@"TextInputMode: %ld", self.textDocumentProxy.keyboardType);

}
