NSDictionary writeToFile未写入

Question

我使用有效的字典运行以下代码，但仍然得到"not written"：

 NSFileManager* fm = [[NSFileManager alloc] init];
 __autoreleasing NSError* err = nil;

 NSURL* DD = [fm URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:YES error:&err];
 if (!err) {
     NSString* debugPath = [[DD path] stringByAppendingPathComponent:@"debug.plist"];

     NSLog(@"login-signup write that file!");
     NSDictionary* remMe = [NSDictionary dictionaryWithObjectsAndKeys:[userJSON objectForKey:kRememberMeToken],kRememberMeToken,[userJSON objectForKey:@"id"],@"id",nil];

     NSMutableDictionary* toStore = [NSMutableDictionary dictionaryWithDictionary:dict];
     [toStore setObject:Password.text forKey:kPassword];
     NSMutableDictionary* toStoreTwo = nil;
     if([fm fileExistsAtPath:debugPath]){
           toStoreTwo = [NSMutableDictionary dictionaryWithContentsOfFile:debugPath];
           [toStoreTwo setObject:[toStore copy] forKey:@"signup"];
           [toStoreTwo setObject:remMe forKey:@"login"];
     }
     else{
           toStoreTwo = [NSMutableDictionary dictionaryWithObject:[toStore copy] forKey:@"signup"];
           [toStoreTwo setObject:remMe forKey:@"login"];
     }

     NSDictionary* sDict = [NSDictionary dictionaryWithObject:toStoreTwo forKey:[NSString stringWithFormat:@"signup-debug-%@",[NSDate date]]];

     NSLog(@"saving %@ to file",sDict);
     BOOL success = [sDict writeToFile:debugPath atomically:NO];
     if(!success){
            NSLog(@"not written");
     }
     else{
            NSLog(@"written");
     }
   }

任何帮助都是最好的！

Stackoverflow需要更多的内容来解释代码，但我认为很容易看到发生了什么，如果你有任何问题，请发表意见！

看看这个问题，write to file fails。我有一些问题，但在检查了我的字典中的所有数据类型后发现了错误。
