Question

我已经覆盖了UIViewController中的-inputAccessoryView:方法，该方法返回一个显示在键盘顶部的视图，该视图在viewController视图上编辑UITextField时显示。

-(UIView *)inputAccessoryView;

我还在viewController中展示了一个UIAlertController。

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Save Profile" message:@"You have made changes to your profile. Do you want to save them?" preferredStyle:UIAlertControllerStyleAlert];
[alert addAction:[UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:nil]];
[alert addAction:[UIAlertAction actionWithTitle:@"Save" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
        //Code to save the profile.
    }]];
[self presentViewController:alert animated:YES completion:nil];

如您所见，我没有将任何textField添加到UIAlertController。

奇怪的是，当呈现UIAlertController时，inputAcessoryView会出现在屏幕的底部。

这是一个错误，还是我忽略了什么？

Answer 1

将输入附件视图重命名为inputAccessoryView以外的其他视图。例如keyboardaccessoryView。

然后添加以下行

self.m_textFieldName.inputAccessoryView = [self keyboardInputAccessoryView];

这解决了我的问题。

Answer 2

请勿使用名称＆＃39; inputAccessoryView＆＃39;

这将解决..！

    - (UIView *)CustominputAccessoryView {
    if (!keyboardinputAccessoryView) {
        CGRect accessFrame = CGRectMake(0.0, 0.0, [UIScreen mainScreen].bounds.size.width, 40.0);
        keyboardinputAccessoryView = [[UIView alloc] initWithFrame:accessFrame];
        keyboardinputAccessoryView.backgroundColor = [UIColor  colorWithRed:0/255.0f green:0/255.0f blue:0/255.0f alpha:0.6];
        UIButton *compButton = [UIButton buttonWithType:UIButtonTypeCustom];
        compButton.frame = CGRectMake([UIScreen mainScreen].bounds.size.width-60, 0.0, 50, 40.0);
        [compButton setTitle: @"Done" forState:UIControlStateNormal];
        compButton.titleLabel.textColor = [UIColor blueColor];
        [compButton setTitleColor:self.view.tintColor forState:UIControlStateNormal];
        [compButton addTarget:self action:@selector(completeCurrentWord:)
             forControlEvents:UIControlEventTouchUpInside];
        [keyboardinputAccessoryView addSubview:compButton];
    }
    return keyboardinputAccessoryView;
}

keyboardinputAccessoryView 只是一个UIView

@property (readonly, retain) UIView *keyboardinputAccessoryView;

然后制作＆＃39; CustominputAccessoryView＆＃39;作为textField的inputAccessoryView

- (void)textFieldDidBeginEditing:(UITextField *)textField {
 textField.inputAccessoryView = [self CustominputAccessoryView];
}

Answer 3

遇到同样的问题，你可以试试

textFirld.resignFirstResponder()

在呈现AlertViewController之前。

它对我有用。

Answer 4

你有UITextField的属性，比如inputAccessoryView，所以它已经过了它。如果可能的话

只需更改视图名称

即可

-(UIView *)inputAccessoryView;

到某个名字

-(UIView *)alertDisplayView;

这将解决..！我不知道你为什么用名称inputAccessoryView来获取视图..！

希望它可以帮助你......！
