UIApperance和各种崩溃
在定制我的应用程序时，我变得非常沮丧。 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，但每当MFMailComposeViewController，MFMessageComposerViewController，Twitter或Facebook共享者甚至QuickLook View Controller进场时，应用程序都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composer php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。
因此，我不想删除邮件撰写function或邮件撰写function。
有没有人遇到过这个bug？
我已经有代码写了。 问题是由于自定义UINavigationBars元素，UIAppearance使应用程序崩溃。 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]; } }
出现
- (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"]]; }
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。
refreshControl外观也是一样：必须在tableView的类中设置它。
你需要为twitter，facebook添加必要的框架。
对于电子邮件，请执
将MessageUI.framework添加到您的项目中
在你的.h文件中
#import @interface CustomController : UIViewController
在.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]; }
在.h文件中添加委托
在.m文件中添加以下内容
-(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]; }
