iOS开发中如何设置请求超时时间


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的设置请求超时时间.

 

对于SDWebImage来说

在在SDWebImageDownloader.m文件中的 downloadImageWithURL.

具体为:

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

主要是:

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

决定。

 

如果请求超时之后我们可以取消AFN的请求,通过以下代码实现:

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