iphone - 删除 uibutton 文本中的阴影

Question

我使用以下代码来自定义自定义 UIBarButtonItem的文本：

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得到了一点阴影。

我怎样才能消除那个阴影？

Answer 1

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,

[UIColor clearColor], UITextAttributeTextShadowColor, nil]

forState:UIControlStateNormal];
