服务器返回的XML格式：
因为苹果没有提供直接获取xml开始标签和结束标签中间的字符串，虽然提供了
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string；
这个方法获取中间的字符串，但是这个字符串包含了空格和回车，所以要在这个方法中进行过滤。
源代码如下：
#import "RecommendController.h"
11 #import "SPHTTPRequestTool.h"
13 #import "UIImageView+WebCache.h"
14 @interface RecommendController ()<NSXMLParserDelegate>

18 @property (nonatomic, strong)NSMutableDictionary *itemDict;
19
20 @property (nonatomic, strong)NSMutableArray *itemArray;
21
22 @property (nonatomic, copy)NSString *itemName; // 记录标签名
23
24 @end

如果报错：可能原因
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc] init];
manager.responseSerializer = [AFXMLParserResponseSerializer serializer]; // 返回XML时，这句话不写，会报错。
