解析为目标C URL地址

问题描述：

我试图获取元数据的URL地址元头，我使用此代码解析为目标C URL地址

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://www.youtube.com/watch?v=1cuMAeGOCng"]]; 
    [request setValue:@"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Safari/601.1.42" 
    forHTTPHeaderField:@"User-Agent"]; 

    self.session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; 
    NSURLSessionTask *task = [self.session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) { 
     NSLog(@"%@",data); 
    }]; 
    [task resume];

是这样吧？也返回的数据进行编码，并不能如何解码！任何线索？

由于

它是正确转换的NSData到的NSString 的NSLog（@ “％@”，[[ALLOC的NSString] initWithData：数据编码：NSUTF8StringEncoding]）; –

@MohammadAlavi是的，数据现在是可读的，但获取的信息是关于整个网站！ – OXXY

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: 
[NSURL URLWithString:@"https://www.youtube.com/watch?v=1cuMAeGOCng"]]; 
[request setValue:@"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Safari/601.1.42" 
forHTTPHeaderField:@"User-Agent"]; 

session = [NSURLSession sessionWithConfiguration: 
[NSURLSessionConfiguration defaultSessionConfiguration]]; 

NSURLSessionTask *task = [session dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) 
          { 

    NSString * text = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding]; 
     NSLog(@"Data = %@",text); 


          }]; 
    [task resume];
