注意:
1.创建继承自AFHTTPSessionManager的单例类;
2.下载任务里的重要方法:NSURL *cacheDirectoryPath = [[NSFileManager defaultManager] URLForDirectory:NSCachesDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil]; return [cacheDirectoryPath URLByAppendingPathComponent:[response suggestedFilename]];
3.上传任务里的重要方法:[formData appendPartWithFileData:UIImagePNGRepresentation(image) name:imagekey fileName:@"01.png" mimeType:@"image/png"];
