在iOS 7上更改MFMailComposerViewController中的导航按钮颜色 [英] Change navigation button color in MFMailComposerViewController on iOS 7
问题描述
我正在尝试更改MFMailComposerViewController中导航按钮的文本颜色，但它在iOS 6上不起作用。在iOS 6中，它与UIAppearance一起工作如下：
I'm trying to change the text color for navigation buttons in a MFMailComposerViewController but it doesn't work like on iOS 6. In iOS 6 it worked with UIAppearance like this:
// Navigation button
UIBarButtonItem *barButton = [UIBarButtonItem appearance];
NSDictionary *barButtonTitleTextAttributes = @{UITextAttributeTextColor: [UIColor redColor]};
NSDictionary *disabledBarButtonTitleTextAttributes = @{UITextAttributeTextColor: [UIColor grayColor]};
[barButton setTitleTextAttributes:barButtonTitleTextAttributes forState:UIControlStateNormal];
[barButton setTitleTextAttributes:disabledBarButtonTitleTextAttributes forState:UIControlStateDisabled];
[barButton setBackgroundImage:[[UIImage imageNamed:@"btn_appearance"] stretchableImageWithLeftCapWidth:6 topCapHeight:0] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
但这在iOS 7上不起作用，看起来总是这样：
But this doesn't work on iOS 7 and looks always like this:
我也尝试设置<导航栏上的code> tintColor 属性，但这也没有效果：
I also tried to set the tintColor attribute on the navigationBar but this has no effect either:
navigationBar.tintColor = [UIColor redColor];
无论如何要改变iOS 7上MFMailComposeViewController中的导航按钮文本颜色？
Is there anyway to change the navigation button text color in a MFMailComposeViewController on iOS 7?
推荐答案
我用过这个并在iOS7 +中完美运作
I used this and works perfect in iOS7+
MFMailComposeViewController* mailViewController = [[MFMailComposeViewController alloc] init];
mailViewController.mailComposeDelegate = self;
[mailViewController setToRecipients:@[@"email@apple.com"]];
[mailViewController.navigationBar setTintColor:[UIColor orangeColor]];
[self presentViewController:mailViewController animated:YES completion:nil];
