Question

这是我正在使用的代码，它可以在模拟器中运行，但在idevice中没有显示任何内容。如果我通过ifunbox添加文件夹或文件，它会显示在设备中。我是否需要任何创建或添加文件的权限？

    NSError *error;
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
    NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat: @"/Folders/%@", self.txtFolder.text]];
    NSLog(@"%@", dataPath);

    if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
    {
        [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder

        [sec1Contents addObject:self.txtFolder.text];
        sec1 = [NSArray arrayWithArray:sec1Contents];
        [self.tblFiles reloadData];
    }

提前感谢。

    Use this code :    

NSURL *allitemsImageurl =[NSURL URLWithString: url];
    NSData *allItemsImageData = data1;  // Load XML data from web
    NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,  NSUserDomainMask, YES);
    NSString * documentsDirectoryPath = [paths objectAtIndex:0];

    NSString *st1=[ @"img_" stringByAppendingString:[NSString stringWithFormat:@"%d.png",imageCount]];

    NSString *allitemsImagePath = [documentsDirectoryPath stringByAppendingPathComponent:st1];
    NSLog(@"%@",allitemsImagePath);
    [allItemsImageData writeToFile:allitemsImagePath atomically:TRUE];

添加到文档目录的文件显示在Simulator中，但在iphone中没有
