删除uibutton文本中的阴影

Question

我使用以下代码自定义自定义UIBarButtonItem 的 text ：

editButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemEdit target:self action:@selector(editPressed)];
    self.navigationItem.rightBarButtonItem = editButton;
[editButton setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys: [UIFont fontWithName:@"HelveticaNeue" size:17.0], UITextAttributeFont, nil] forState:UIControlStateNormal];

但是titleText会有一点影子。

如何删除该影子？

    self.navigationItem.rightBarButtonItem = editButton;
[editButton setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys: [UIFont fontWithName:@"HelveticaNeue" size:17.0], UITextAttributeFont,

[UIColor clearColor], UITextAttributeTextShadowColor, nil]

forState:UIControlStateNormal];
