我正在努力合并s MFMailComposer
,以便在我的应用中发送短信。下面是我创建和显示消息共享组件的代码:
- (void)shareWithMessages {
if(![MFMessageComposeViewController canSendText]) {
UIAlertView *warningAlert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Your device doesn't support SMS!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[warningAlert show];
return;
}
NSString *message = self.articleTitle;
message = [message stringByAppendingString:@" "];
message = [message stringByAppendingString:self.urlString];
MFMessageComposeViewController *messageController = [[MFMessageComposeViewController alloc] init];
messageController.messageComposeDelegate = self;
[messageController setBody:message];
// Present message view controller on screen
[self presentViewController:messageController animated:YES completion:nil];
}
当显示共享作曲家时,"新消息"文字以白色显示:
我尝试设置色调颜色如下:
[[messageController navigationBar] setTintColor:[UIColor blackColor ]];
......但这没有效果。有谁知道为什么文本设置为白色,因此不可读?
答案 0 :(得分:0)
您的代码中可能正在改变[UINavigationBar外观]。因此,在调用
之前尝试设置UINavigationBar的外观shareWithMessage
以下3个中的一个可能会做到这一点:
[[UINavigationBar appearance] setTintColor:[UIColor yourColor]];
[[UINavigationBar appearance] setBarTintColor:[UIColor yourColor]];
[[UINavigationBar appearance] setTitleTextAttributes:
@{NSForegroundColorAttributeName:[UIColor yourColor]}];
