ios - 检索文件parse.com的URL

Question

我正在尝试找回刚刚保存的文件的url。但是，在他们的文档中找到的getUrl()方法似乎不起作用。我得到错误:

在类型'PFFile *'的对象上找不到属性'getUrl'

我的代码:

int count = 0;    
PFObject *obj = [PFObject objectWithClassName:@"File"];
    for (NSString* currentString in directoryContents){

        NSString *temp2 = [temp stringByAppendingPathComponent:currentString];
        PFFile *file = [PFFile  fileWithName:currentString contentsAtPath:temp2];
        [file saveInBackground];


        count += 1;

        NSString *filen = [NSString stringWithFormat:@"file%i",count];
        NSLog(@"%@",filen);


        [obj setObject:file forKey:filen];
        NSString* url = file.getUrl();
    }

        [obj saveInBackground];

您想将file.url用作documented。
