ios - InputAccessoryView 内容显示在弹出键盘键上

Question

自从我升级到 Xcode 5.1 后，我的 inputAccessoryView 出现了问题。

如您在附图中所见，按键在 inputAccessoryView 内的工具栏后面弹出。我认为它与新版本的 xcode 有关，因为它与以前版本的 xcode 没问题。

创建和添加附件 View 的代码:

    self.keyboardDoneButtonView = [[UIToolbar alloc] init];
    self.keyboardDoneButtonView.barStyle = UIBarStyleBlack;

    self.addEmailUITextField = [[UITextField alloc] init];
    [self.addEmailUITextField setReturnKeyType:UIReturnKeySend];
    [self.addEmailUITextField setBorderStyle:UITextBorderStyleRoundedRect];
    [self.addEmailUITextField setAutocorrectionType:UITextAutocorrectionTypeNo];
    [self.addEmailUITextField setAutocapitalizationType:UITextAutocapitalizationTypeNone];
    [self.addEmailUITextField setKeyboardType:UIKeyboardTypeEmailAddress];
    [self.addEmailUITextField setClearButtonMode:UITextFieldViewModeWhileEditing];
    [self.addEmailUITextField setKeyboardAppearance:UIKeyboardAppearanceDark];
    [self.addEmailUITextField setPlaceholder:NSLocalizedString(@"emailHint", nil)];

    self.cancel = [[UIButton alloc] init];
    [self.cancel setTitleColor:[UIColor khipuSecondaryColor] forState:UIControlStateNormal];
    [self.cancel setTitle:NSLocalizedString(@"cancel", nil) forState:UIControlStateNormal];
    [self.cancel addTarget:self action:@selector(hideAddEmailTextField) forControlEvents:UIControlEventTouchUpInside];
    [self.cancel sizeToFit];
    self.cancel.frame = CGRectMake((self.tableView.frame.size.width - (self.cancel.frame.size.width + 20)), self.cancel.frame.origin.y, self.cancel.frame.size.width, self.cancel.frame.size.height);
    self.addEmailUITextField.frame = CGRectMake(5, 7, (self.cancel.frame.origin.x - 10) - 5, 30);
    UIBarButtonItem *cancelUIBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:self.cancel];
    UIBarButtonItem *textFieldItem = [[UIBarButtonItem alloc] initWithCustomView:self.addEmailUITextField];

    [self.keyboardDoneButtonView setItems:[NSArray arrayWithObjects:textFieldItem,cancelUIBarButtonItem, nil]];
    [self.keyboardDoneButtonView sizeToFit];
    self.hiddenUITextField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
    self.hiddenUITextField.inputAccessoryView = self.keyboardDoneButtonView;
    [self.hiddenUITextField setKeyboardAppearance:UIKeyboardAppearanceDark];
    [self.addEmailUITextField setDelegate:self];

这段代码在 xcode 升级之前一直运行良好

任何人都可以阐明这个问题吗？

发现问题!:是一个类别。

我在 UIView 上有一个类别用于在 subview 中搜索。

我有一个名为

的方法

- (BOOL)containsView:(UIView *)aUIView;

这打破了行为。更改了方法的名称，现在可以正常工作了。

我不知道，但也许我只是选择私有(private) API 的签名。

感谢您的意见和想法，它帮助我找到了麻烦的根源。
