iOS開發中如何佈建要求逾時時間

 1 NSString *baseUrl; 2     NSURL *url = [NSURL URLWithString:[baseUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; 3     NSURLRequest *request = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10]; 4     AFJSONRequestOperation *jsonOper = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON)  { 5          6     } 8     failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) { 9        10                                                                                        }];

以上是AFN的佈建要求逾時時間.

 

對於SDWebImage來說

在在SDWebImageDownloader.m檔案中的 downloadImageWithURL.

具體為：

1 - (id<SDWebImageOperation>)downloadImageWithURL:(NSURL *)url options:(SDWebImageDownloaderOptions)options progress:(void (^)(NSUInteger,long long))progressBlock completed:(void (^)(UIImage *,NSData *, NSError *, BOOL))completedBlock函數。

主要是：

1 - (id)initWithURL:(NSURL *)URL cachePolicy:(NSURLRequestCachePolicy)cachePolicy timeoutInterval:(NSTimeInterval)timeoutInterval；中的timeoutInterval

決定。

 

如果請求逾時之後我們可以取消AFN的請求,通過以下代碼實現:

 1      // 1.建立AFN管理者 2     AFHTTPRequestOperationManager *mange = [AFHTTPRequestOperationManager manager]; 3      4     // 2.發送請求 5     [mange GET:url parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) { 6         // 請求成功 7         IWLog(@"請求成功"); 8         if (success) { 9             success(responseObject);10         }11         12     } failure:^(AFHTTPRequestOperation *operation, NSError *error) {13         14         IWLog(@"請求失敗");15         if (failure) {16             failure(error);17         }18     }];19     20     //3.取消請求21     [mange.operationQueue cancelAllOperations];
