Question

我在定制我的应用时感到非常沮丧。我已经创建并设计了几乎整个应用程序，包括导航栏，工具栏，tabBar等，但每次MFMailComposeViewController，MFMessageComposerViewController，Twitter或Facebook共享者甚至是QuickLook View Controller都会发挥作用时，应用程序会崩溃并显示以下消息：

*** Assertion failure in -[UICGColor encodeWithCoder:].
*** Terminating app due to uncaught exception 'NSInternalInconsistencyExceptionì, reason: 'Only RGBA or White color spaces are supported in this situation.'

我已经读到这是因为iOS 6将作曲家作为远程控制器进行管理，但我真的不知道如何解决这个问题。

由于这个原因，我不想删除邮件撰写功能或邮件撰写功能。

任何人都遇到过这个错误吗？

我已经编写了代码。问题是由于自定义UINavigationBars元素，UIAppearance正在使应用程序崩溃。代码。

-(void)message{
    if (_progressHUD){
        [_progressHUD hide:YES];
    }
    MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init] ;
    [controller setMessageComposeDelegate:self];

    if([MFMessageComposeViewController canSendText])
    {
        controller.body = descriptionString;
        controller.recipients = nil;
        [self presentViewController:controller animated:YES completion:nil];
    }

}

-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result{
    [self dismissViewControllerAnimated:YES completion:nil];
}

-(void)email {

    if (_progressHUD){
        [_progressHUD hide:YES];
    }

    MFMailComposeViewController *composer = [[MFMailComposeViewController alloc] init];
    [composer setMailComposeDelegate:self];
    if ([MFMailComposeViewController canSendMail]) {
        [composer setToRecipients:nil];
        [composer setSubject:[NSString stringWithFormat:@"%@",nameString]];

        [composer setMessageBody:[NSString stringWithFormat:@"%@",descriptionString] isHTML:NO];        [composer addAttachmentData:[NSData dataWithContentsOfURL:[NSURL URLWithString:imageString]] mimeType:@"png" fileName:imageString];
        [composer setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
        [self presentViewController:composer animated:YES completion:nil];
    }
}


-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {
    if (error) {
        SIAlertView *alert = [[SIAlertView alloc] initWithTitle:@"Error"
                                                        andMessage:[NSString stringWithFormat:@"Error %@", [error description]]];
        [alert addButtonWithTitle:@"OK" type:SIAlertViewButtonTypeDestructive handler:^(SIAlertView *alertView){}];
        [alert show];
        [self dismissViewControllerAnimated:YES completion:nil];
    }
    else {
        [self dismissViewControllerAnimated:YES completion:nil];
    }
}

外观

- (void)customizeAppearance
{
    [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

    UINavigationBar Appearance
    [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"navigationBarBackground"] forBarMetrics:UIBarMetricsDefault];
    [[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
    [[UINavigationBar appearance] setTitleTextAttributes:
     [NSDictionary dictionaryWithObjectsAndKeys:
      [UIColor whiteColor],
      UITextAttributeTextColor,
      [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.0],
      UITextAttributeTextShadowColor,
      [NSValue valueWithUIOffset:UIOffsetMake(0, -1)],
      UITextAttributeTextShadowOffset,
      [UIFont fontWithName:@"HelveticaNeue" size:0.0],
      UITextAttributeFont,
      nil]];

    //ToolBar Appearance
    [[UIToolbar appearance] setTintColor:[UIColor whiteColor]];


    //Switch Appearance
    [[UISwitch appearance] setOnTintColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"greenBackground"]]];

    //Search Bar Appearance
    [[UISearchBar appearance] setTintColor:[UIColor whiteColor]];

    //Tab Bar Appearance
    [[UITabBar appearance] setBackgroundImage:[UIImage imageNamed:@"tabBarBackground"]];
    [[UITabBar appearance] setTintColor:[UIColor whiteColor]];
    [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], UITextAttributeTextColor, nil] forState:UIControlStateNormal];
    [[UITabBar appearance] setSelectionIndicatorImage:[UIImage imageNamed:@"transparent"]];

}

Answer 1

在各种调试会话之后，我整理出了给我这些崩溃的代码行

//Switch Appearance
[[UISwitch appearance] setOnTintColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"greenBackground"]]];

所以我删除了它，一切正常。显然，我不能直接在AppDelegate中设置外观，但我必须在交换机所在的类中进行。

对于refreshControl外观也是如此：必须在tableView的类中设置它。

您需要为twitter，facebook添加必要的框架。
对于电子邮件，请执行以下操作：

将MessageUI.framework添加到您的项目

在你的.h文件中

#import <MessageUI/MessageUI.h>

@interface CustomController : UIViewController<MFMailComposeViewControllerDelegate>

在你的.m文件中

- (IBAction)actionEmail:(id)sender
{
NSLog(@"actionEmail Called");

MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
mc.mailComposeDelegate = self;
[self presentViewController:mc animated:YES completion:NULL];


}

- (void) mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
switch (result)
{
    case MFMailComposeResultCancelled:
        NSLog(@"Mail cancelled");
        break;
    case MFMailComposeResultSaved:
        NSLog(@"Mail saved");
        break;
    case MFMailComposeResultSent:
        NSLog(@"Mail sent");
        break;
    case MFMailComposeResultFailed:
        NSLog(@"Mail sent failure: %@", [error localizedDescription]);
        break;
    default:
        break;
}

// Close the Mail Interface
[self dismissViewControllerAnimated:YES completion:NULL];
}

Answer 3

在您的.h文件中添加代理 <MFMessageComposeViewControllerDelegate,MFMailComposeViewControllerDelegate>

在您的.m文件中添加以下

 -(void)ShareByEmail:(NSString *)strEmail {
        MFMailComposeViewController *mail = [[MFMailComposeViewController alloc] init];
        mail.mailComposeDelegate = self;
        if ([MFMailComposeViewController canSendMail]) {

            NSString *bodyData = @"Boy data place here";


                NSString *strRecipients = [NSString stringWithFormat:@"%@",strEmail];
                strRecipients = [strRecipients stringByReplacingOccurrencesOfString:@"mailto:" withString:@""];
                NSArray * arrayRecipients = [strRecipients componentsSeparatedByString:@""];

                [mail setToRecipients:arrayRecipients];

            [mail setSubject:@"Subject"];
            [mail setMessageBody:bodyData isHTML:NO];
            [self presentViewController:mail animated:YES completion:nil];
        }
        mail = nil;
        return NSLog(@"%@",strEmail);
    }

-(void)shareBySMS:(NSString *)strSMS {
   if([strSMS length] > 0) {
            MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
            if(picker) {
                picker.messageComposeDelegate = self;

                    picker.recipients = @"Youre Recipients";
                    //picker.recipients = [NSArray arrayWithObject:tel];
                    picker.body = strSMS;

                [self presentViewController:picker animated:NO completion:nil];
                picker = nil;
            }
            NSLog(@"SMS fired");
        }
}


#pragma mark Mail Composer Delegate Methods

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {

    // Notifies users about errors associated with the interface
    switch (result) {
        case MFMailComposeResultCancelled:
            break;
        case MFMailComposeResultSaved:
            break;
        case MFMailComposeResultSent:
            break;
        case MFMailComposeResultFailed:
            break;
        default:
            break;
    }
    [self dismissViewControllerAnimated:YES completion:nil];
}

    - (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {
        switch (result) {
            case MessageComposeResultCancelled:
                NSLog(@"Result: canceled");
                break;
            case MessageComposeResultSent:
                NSLog(@"Result: sent");
                break;
            case MessageComposeResultFailed:
                NSLog(@"Result: failed");
                break;
            default:
                NSLog(@"Result: not sent");
                break;
        }
        [self dismissViewControllerAnimated:YES completion:nil];
    }
