我想分析從目標C捲曲基地web服務數據圖像和我使用的代碼

我想從捲曲web服務的數據，但我的代碼是不工作我想分析從目標C捲曲基地web服務數據圖像和我使用的代碼

NSURL *url = [NSURL URLWithString:delegate.profilePic]; 
     NSMutableURLRequest *req = [[NSMutableURLRequest alloc] initWithURL:picUrl]; 
    [req setValue:@"application/json" forHTTPHeaderField:@"Accept"]; 
     [req setValue:@"application/octet-stream" forHTTPHeaderField:@"Content-Type"]; 
     NSString *token =delegate.Token; 
     [req setValue:token forHTTPHeaderField:@"X-Auth-Token"]; 
    [req setHTTPMethod:@"GET"]; 
    NSError *error = nil; 
    NSURLResponse *response; 
    NSData *urlData=[NSURLConnection sendSynchronousRequest:req returningResponse:&response error:&error]; 
    NSString *myString = [[NSString alloc] initWithData:urlData encoding:NSUTF8StringEncoding]; 
     NSLog(@"Url Data %@",myString);

這是非常好的代碼！有什麼問題？ –

對於初學者，您錯過了這行代碼的末尾：'NSURL * picUrl = [NSURL URLWithString：@「'。請修復它，以便我們可以嘗試提供幫助。 – neilco

試試這個代碼，我用它來獲取圖像數據

dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0ul); 
dispatch_async(queue, ^{ 
    NSURL *url = [NSURL URLWithString:delegate.profilePic]; 
    NSMutableURLRequest *req = [[NSMutableURLRequest alloc] initWithURL:url]; 
    [req setHTTPMethod:@"GET"]; 

    NSString *boundary = @"0x0hHai1CanHazB0undar135"; 
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; 
    [req addValue:contentType forHTTPHeaderField: @"Content-Type"]; 
    [req setValue:delegate.Token forHTTPHeaderField:@"X-Auth-Token"]; 
    NSError *error = nil; 
    NSURLResponse *response; 
    NSData *urlData=[NSURLConnection sendSynchronousRequest:req returningResponse:&response error:&error]; 

    dispatch_sync(dispatch_get_main_queue(), ^{ 

     profilePicView.image=[UIImage imageWithData:urlData]; 
    }); 
});
