UIApperance和各种崩溃 [英] UIApperance and various crashes
问题描述
自定义应用程序时,我感到非常沮丧. 我已经创建并设置了几乎整个应用程序的样式,包括导航栏,工具栏,tabBar等,但是每次MFMailComposeViewController,MFMessageComposerViewController,Twitter或Facebook共享程序甚至QuickLook View Controller出现时,应用程序都会崩溃并显示以下消息:
I'm getting so frustrated while customizing my app. I've already created and styled almost the whole app, including Navigation bar, toolbar, tabBar etc, but everytime a MFMailComposeViewController, a MFMessageComposerViewController, Twitter or Facebook sharers or even a QuickLook View Controller comes in play, the app crashes with the message:
*** 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将作曲家作为遥控器进行管理,但是我真的不知道如何解决此问题.
I've read around that this is because iOS 6 manages the composers as Remote Controllers, but I really haven't any idea how to get a fix to this problem.
因此,我不想删除邮件撰写功能或邮件撰写功能.
I don't want to remove the mail composing features or the message composing features because of this.
也有人遇到此错误吗?
我已经写了代码.问题在于,由于自定义UINavigationBars元素,UIAppearance导致应用程序崩溃. 代码.
I already have the code wrote. The problem is that UIAppearance is making the app crash because of the custom UINavigationBars elements. Code.
-(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];
}
}

//Search Bar Appearance

//Tab Bar Appearance

[[UITabBar appearance] setTintColor:[UIColor whiteColor]];
[[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], UITextAttributeTextColor, nil] forState:UIControlStateNormal];
[[UITabBar appearance] setSelectionIndicatorImage:[UIImage imageNamed:@"transparent"]];
}
推荐答案
经过各种调试会话,我整理出导致崩溃的代码行是
After various debugging session, I sorted out that the line of code that was giving me those crashes was
//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,但必须在开关所在的类中进行设置.
So I deleted it and everything was working fine. Apparently, I can't set the appearance directly in the AppDelegate, but I had to do it in the class where the switch was in.
refreshControl外观也是如此:必须在tableView的类中进行设置.
Same thing for the refreshControl appearance: had to set it in the tableView's class.
