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的設置請求超時時間.
對於SDWebImage來說
在在SDWebImageDownloader.m文件中的 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。
如果請求超時之后我們可以取消AFN的請求,通過以下代碼實現:
1 // 1.創建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];
