如何解决如何在iPhone中存储xml值并在数组中计数以及如何在iphone的tableview单元中显示值
|| 嗨，朋友，谢谢我从xml中获取数据的结果，我可以在控制台中看到在控制台中看到的所有元素值，但是我的NSLog中的问题是问题（@ \“ 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，请脸颊一些，告诉我解析器代码在做什么错 请同时检查我正在创建并帮助我的朋友的类解析器和控制器类 这是我的parser.h文件----------------- /#import \"TWeatherElement.h\"//this is the class where the elements are Created
