MFMailComposeViewController栏背景颜色在iOS7中没有变化

问题描述

我正在 iOS7 中更改 MFMailComposeViewController 的背景颜色，但我无法正常工作。

I'm trying to change the background color of the MFMailComposeViewController in iOS7 but I cannot make it work.

我正在使用以下剪辑：

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;

if([picker.navigationBar respondsToSelector:@selector(barTintColor)]) {
    // iOS7
    picker.navigationBar.barTintColor = READER_NAVIGATION_BAR_BACKGROUND_COLOR;
    // Set back button arrow color
    [picker.navigationBar setTintColor:READER_NAVIGATION_BAR_BACK_BUTTON_ARROW_COLOR];

    // Set Navigation Bar Title Color
    [picker.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObject:READER_NAVIGATION_BAR_TITLE_NORMAL_FONT_COLOR forKey:UITextAttributeTextColor]];

    // Set back button color
    [[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:READER_NAVIGATION_BAR_BUTTONS_FONT_COLOR, UITextAttributeTextColor,nil] forState:UIControlStateNormal];

} 

有谁知道如何改变 MFMailComposeViewController ？

推荐答案

试试这个。为我工作。

MFMailComposeViewController* myailViewController = [[MFMailComposeViewController alloc] init];
// set other attributes of mailcomposer here.
myMailViewController.mailComposeDelegate = self;

[myMailViewController.navigationBar setTintColor:[UIColor whiteColor]];

[self presentViewController:myMmailViewController animated:YES completion:nil];
