删除UIBarButtonItem的文本阴影

Question

我已经调整了UIBarButtonItem以使用自定义字体和颜色属性

self.followButton = [[[UIBarButtonItem alloc]

                             initWithTitle: NSLocalizedString(@"TWITTER_FOLLOW_BUTTON_TEXT", nil)
                             style:UIBarButtonItemStylePlain
                             target:self
                             action:@selector(handleFollowButtonPressed:)]
                            autorelease];  

,

[self.followButton setBackgroundImage:[UIImage new] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];  

,

[followButton setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys: [UIFont fontWithName:@"Helvetica" size:14.0], UITextAttributeFont,nil] forState:UIControlStateNormal];  

和

NSDictionary *attributes = @{UITextAttributeTextColor : [UIColor colorWithRed:1 green:0.176 blue:0.333 alpha:1 /*#ff2d55*/ ]};

    [followButton setTitleTextAttributes:attributes
                            forState:UIControlStateNormal]; 

得到的外观

如何在不改变图像的情况下删除buttonitem的文本阴影？

Answer 1

将UIBarButtonItem's UITextAttributeTextShadowOffset属性设置为UIOffsetMake(0.0, 0.0).

你需要将它存储UIOffset在一个NSValue对象中:[NSValue valueWithUIOffset: UIOffsetMake(0.0, 0.0)].
