hi all, am programing a simple app, i wanted to read the content of a file uisng the code:

Code:

 NSFileManager *filemgr;
        NSString *currentPath;
        
        filemgr =[NSFileManager defaultManager];
        currentPath = [filemgr currentDirectoryPath];
        
        NSString *name = [currentPath stringByAppendingPathComponent:@"sample.txt"];

        NSError *error = nil;

        
        NSString* content = [NSString stringWithContentsOfFile:name
                                                      encoding:NSUTF8StringEncoding
                                                         error:&error];
      if(error) { // If error object was instantiated, handle it.
          NSLog(@"ERROR while loading from file: %@", error);

      }

       NSLog(@"%@",content);
