如何存储 xml 值并在数组中计数并在 iphone 的 tableview 单元格中显示值

Question

嗨朋友感谢我从 xml 获取的数据，结果我可以在控制台中看到我在控制台中看到的所有元素值，但我的问题在我的 NSLog(@"mDataArray count = %d",[mParserArray count]); 我在 mdataarray 中看不到任何计数值这是我的解析器代码请找人告诉我我在解析器代码中做错了什么

请同时关注我创建的 class 解析器和 controller class 并帮助我朋友这是我的 parser.h 文件-----------------/

#import "TWeatherElement.h"//this is the class where the elements are Created
#import <Foundation/Foundation.h>


@interface TWeatherParser : NSObject<NSXMLParserDelegate> 
{
    NSMutableArray *mParserArray;
    NSXMLParser *mXmlParser;
    NSMutableString *mCurrentElement;
    BOOL elementFound;
    TWeatherElement *mWeather;

}
@property (nonatomic, retain) NSMutableString *currentElement;
@property (nonatomic, retain)NSMutableArray *mParserArray;
@property (nonatomic, retain) TWeatherElement *weatherobj;

-(void)getInitialiseWithData:(NSData *)inData;

@end

Answer 1

NSLog(@"this is success %@",ap.dataReply);
        TWeatherParser *parser = [[TWeatherParser alloc]init];
        [parser getInitialiseWithData:ap.dataReply];
        [parser release];

初始化你的mParserArray = [NSMutableArray array]; 在这里，您需要将解析后的数组存储到某个变量中。 你不这样做。 从您的代码中， weatherarray是应该保存解析值的变量。 我希望这能为您指明正确的方向。 要么让self.weatherarray指向parser. mParserArray parser. mParserArray或使用您的计划。
