AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
manager.requestSerializer.cachePolicy = NSURLRequestReturnCacheDataDontLoad;
AFHTTPResponseSerializer *responseSerializer = [AFHTTPResponseSerializer serializer];
responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];
manager.responseSerializer = responseSerializer;
[manager GET:@"http://www.github.com" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"%@", [[NSString alloc]initWithData:responseObject encoding:NSUTF8StringEncoding]);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
}];
为何我即使设置cachePolicy为DontLoad，这段代码执行时仍然会从服务器读取数据
