在ASIHTTPRequest中接收内存警告以在iOS7中上载多个图像

Question

我正在使用ASIHTTPRequest在iOS7上传多个图像，我在上传大尺寸（每个4MB）图像时收到内存警告。我将转换base64编码中的所有图像并将服务器上的base64数据上传到上面。< / p>

这是我的代码：

-(void)UploadImages:(NSMutableDictionary *)dictdata
{
            NSString *strURL = [NSString stringWithFormat:@“here is url ”];
            NSURL* url = [[NSURL alloc] initWithString:strURL];
            ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];

           for (int i = 0; i < [dicData count] ; i++) {

                NSString *strKey = [[dicData allKeys] objectAtIndex:i];
                NSString *strValue = [dicData objectForKey:strKey];
                [request setPostValue:strValue forKey:strKey];
            }
           [request addRequestHeader:@"Content-Type" value:@"application/x-www-form-urlencoded"];
 [request setUploadProgressDelegate:appDelegate.progressIndicator];
                [request setUploadProgressDelegate:delegate];
                [request  setShouldStreamPostDataFromDisk:YES];
                request.cachePolicy = NSURLRequestReloadIgnoringLocalCacheData;

                request.showAccurateProgress = TRUE;
                [request setDelegate:delegate];
                [appDelegate.request setTimeOutSeconds:60000];
               request.shouldAttemptPersistentConnection = NO;

              [request setDidFinishSelector:@selector(uploadRequestFinished:)];
            [request setDidFailSelector:@selector(uploadRequestFailed:)];
            [request startAsynchronous];
