这是代码:

 +(NSString *)ServerAddressFileInDocument
    {
        NSString *docPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
        return [docPath stringByAppendingPathComponent:@"ServerAddress.plist"];
    }

+ (void)loadServerAdressList:(NSMutableArray *)marketArray dealArray:(NSMutableArray *)dealArray 
{ 
      NSData *data = [NSData dataWithContentsOfFile:[FilePathsManager        ServerAddressFileInDocument]]; 
      NSKeyedUnarchiver *unArchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data];
      [marketArray setArray:[unArchiver decodeObjectForKey:@"market"]]; 
      [dealArray setArray:[unArchiver decodeObjectForKey:@"deal"]]; 
      [unArchiver finishDecoding]; [unArchiver release];
 } 

在此崩溃报告中，这是否意味着应用程序在“NSSearchPathForDirectoriesInDomains”处崩溃？我不熟悉崩溃报告，感谢您的帮助。

Answer 1

在 (FilePathsManager.m:90) 运行“[FilePathsManager ServerAddressFileInDocument]”时，您的应用程序似乎崩溃了
