Ios 外观和各种碰撞
在定制我的应用程序时,我感到非常沮丧。 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、选项卡栏等,但每次使用MFMailComposeViewController、MFMessageComposeViewController、Twitter或Facebook共享程序,甚至QuickLook视图控制器时,应用程序都会崩溃,并显示以下消息:Ios 外观和各种碰撞,ios,objective-c,uiappearance,Ios,Objective C,Uiappearance,在定制我的应用程序时,我感到非常沮丧。 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、选项卡栏等,但每次使用MFMailComposeViewController、MFMessageComposeViewController、Twitter或Facebook共享程序,甚至QuickLook视图控制器时,应用程序都会崩溃,并显示以下消息: *** Assertion failure in -[UICGColor encodeWithCoder:]. *** Terminating app

我读过很多书,这是因为iOS 6将作曲家作为遥控器进行管理,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功能或邮件撰写功能
有人也遇到过这个错误吗
我已经编写了代码。问题是UIAppearance由于自定义UINavigationBars元素而导致应用程序崩溃。
代码
外表
- (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.h文件中添加代理
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");
}
}

你需要为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
添加到项目中
在您的.h文件中
#import <MessageUI/MessageUI.h>
@interface CustomController : UIViewController<MFMailComposeViewControllerDelegate>
在各种调试会话之后,我发现导致崩溃的代码行是
//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,但我必须在开关所在的类中设置外观
refreshControl外观也是一样:必须在tableView的类中设置它。试试这个我已经试过了,我可以使用Google,但我没有找到任何修复方法。伙计,我已经有了所有的代码,必要的框架和所有的东西。问题是UIAppearance正在使其崩溃,因为我有一个自定义UINavigationBar,我几乎应用于应用程序的所有部分。编辑了原始问题。Thx Pheel,我在您的回答的帮助下找到了问题的解决方案。:)谢谢对我来说,这是
[[UITableView外观]setBackgroundColor:[uicolorWithPatternImage:someimage]]代码>它似乎与[uicolorWithPatternImage:image]有明确的链接。对我来说,这是UIPageControl的定制。对我来说,使用colorWithPatternImage:当使用第三方键盘时,它会崩溃,否则一切正常。谢谢Pheel!你给了我一个非常奇怪的错误的解决方案!干杯
