User Profile

one of our clients stored to many files as it seems.following CODE:+(NSArray *)setDirContent{ //load Content of User Directory in file NSDate *logFileDate = [NSDate date]; NSString *dirCont = [NSString stringWithFormat:@"%@ created: %@\n\n",DIRCONTENT,logFileDate]; NSString *resourcePath = [self getSystemDirectory]; NSError *error; NSFileManager *fileManager = [NSFileManager defaultManager]; NSArray *directoryContents = [fileManager contentsOfDirectoryAtPath:resourcePath error:&error]; for (int i=0;i<directoryContents.count;i++) { dirCont = [NSString stringWithFormat:@"%@,\n%@",dirCont,directoryContents[i]]; } NSString *statFilePath = [NSString stringWithFormat: @"%@%@%@",[self getClientDirectory],DIRCONTENT,TXTFILE]; NSData *fileContent = [dirCont dataUsingEncoding:NSUTF8StringEncoding]; NSFileHandle *handle; handle = [NSFileHandle fileHandleForWritingAtPath: statFilePath]; [fileManager createFileAtPath: statFilePath contents:fileContent attributes:nil]; return directoryContents;}READS the directory content and stores it into a file.but since a few weeks for one client the app can not execute this code any longer because the app crashes.What could we do to get the content of the directory into a file?Thanks for your ideas !
