iPhone應用程序中UITableview中的xml數據

Question

如何根據xml數據的屬性字段在UITableView中顯示xml數據？

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *) string {
[currentElementValue appendString:string];

}
- (void) parser:(NSXMLParser *)parser didEndElement:(NSString *) elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
NSLog(@"elementName %@ %@", elementName, currentElementValue);
currentElementValue=nil;
[currentElementValue release];
}

這是一些代碼，我在xml文件中獲取元素名稱。現在我想在UITableView單元上顯示這些數據。

如果我無法表達問題，請敲...。

注意：如果有人給我源代碼，那對我會更好，因為它對我來說非常緊急。

提前致謝。

Answer 1

每次您解析xml數據時，都將該值放入一個數組中，然后將其顯示在tableview中。
