我有一个使用cocoapods的IOS项目.在新计算机上切换计算机并更新操作系统后,当我尝试运行"pod update"时出现以下错误

Robbys-iMac-454:ios-v2 robbykmyers$ pod update

有谁知道如何解决这个问题？

嘿我以前使用过解析器但从未在ARC环境中使用过.现在,当我尝试将解析器设置为self时,它会给出一条错误消息,然后不会解析我的数据.任何人都知道问题是什么以及如何解决？

这是我尝试将解析器委托设置为self时得到的警告:

Semantic Issue: Sending 'CharityController *const __strong' to parameter of incompatible    type 'id<NSXMLParserDelegate>'

这是我的代码:

- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    if (connection == theConnection)
    {
        // do something with the data object.
        //NSLog(@"Data from server is: %@",data);
        NSString *test = [[NSString alloc]initWithData:data encoding:NSStringEncodingConversionAllowLossy];
        NSLog(@"Data from server is: %@",test);
        parser = [[NSXMLParser alloc] initWithData: data]; 
        [parser setDelegate:self];
        [parser parse];
    }
}

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {
    if ([elementName isEqualToString:@"root"]) {
        currentStringValue = nil; …
