Question

我是AFNetworking的新手，所以在使用NSURLConnection之前我从未遇到过这个问题

我在添加类别

的帖子请求后使用此方法

-(void)getCategories{
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    NSString * url = [NSString stringWithFormat:@"%@v2/api/tags",kURL];
    NSDictionary *parameters =[self parameterBuild];
    [manager GET:url parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
        categories = [[NSMutableArray alloc]init];
        categories = [responseObject objectForKey:@"tags"];
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];

}

问题是.. responseObject总是在一段时间内获取旧数据，就像它的缓存一样......

任何帮助将不胜感激

问题来了，因为您没有清理数据并在出错时重新加载视图。

-(void)getCategories{
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    NSString * url = [NSString stringWithFormat:@"%@v2/api/tags",kURL];
    NSDictionary *parameters =[self parameterBuild];
    [manager GET:url parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
        categories = [[responseObject objectForKey:@"tags"] mutableCopy];
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
        categories = [NSMutableArray new];
        // Reload view here, like you do for success
    }];
}
