这里u能看到我的客户阵列是空的..所以朋友和极客请告诉我我要去哪里错了..

感谢和问候 Ranjit

Answer 1

我没有看到你的客户数组的分配？如果没有它的内存，它不能被添加到哪个将暗示为什么它是空的。

customerArray = [[NSMutableArray alloc]initWithCapacity:0]; 

Answer 2

这可能对你有帮助。在parserDidEndDocument:(NSXMLParser *)parser重新加载你的表格。

-(void)parserDidEndDocument:(NSXMLParser *)parser{ 
[reload tblView]; 
}
