的TableView不reloaddata当我点击“更多数据...”在的tableView

请求我的测试web服务的数据的最后一排，的TableView不reloaddata当我点击“更多数据...”在的tableView

的的tableView的最后一行是“更多数据...”

当单击该列，发送另一个请求，以获得更多的数据，

我用[的tableView reloaddata]很多次，但并没有什么

发生了，我不知道why.So，请帮助我这个问题。

预先感谢您。

，并有我的tableViewController.h类：

#import <UIKit/UIKit.h> 

#import "NoticeDetailViewController.h" 

@interface NoticeViewController : UIViewController 
<UITableViewDataSource,UITableViewDelegate> 
{  
    NSMutableArray *allNoticeArray; 

    NSArray *addNoticeArray; 

    NSInteger totalNotice; 

    NSInteger pageIndex; 

    UITableView *tableView; 
} 

@property (nonatomic, retain) NSMutableArray *allNoticeArray; 
@property (nonatomic, retain) NSArray *addNoticeArray; 
@property NSInteger totalNotice; 
@property NSInteger pageIndex; 
@property (nonatomic, retain) UITableView *tableView; 
- (NSMutableArray *)getNoticeList :(NSInteger)pageIndex; 
@end

而且tableViewController.m类：

-Jxdev对不起，这是很多代码。你可以告诉我们，在你调用“更多数据...”之后，numberOfRowsInSection是否返回正确的行数？它看起来像是返回未初始化的'theNumberOfRowsInSection'的情况。 – 2012-03-19 16:05:56

我调用“more data”后NSLog（@“theNumberOfRowsInsection：％d”，theNumberOfRowsInSection） – jxdwinter 2012-03-19 16:17:02

在更多数据...之后更新'allNoticeArray'吗？我认为你的模型并不是最新的以反映你的tableView的变化。 – 2012-03-19 16:24:14

变化：

if ([indexPath row] == [allNoticeArray count])

到：

if ([indexPath row] == [allNoticeArray count]-1)

的原因是阵列（且行）索引是基本为0。所以，如果一个数组，说3个对象，最后目标的指数是2

“theNumberOfRowsInSection = [allNoticeArray count] +1”;如果有更多的数据，我在+1行中的NumberOfRowsInSection函数。只有没有数据要获得，“theNumberOfRowsInSection = [allNoticeArray count]”然后我不需要获取更多的数据 – jxdwinter 2012-03-19 16:21:02

我犯了一个如此愚蠢的错误！另外，谢谢！LOL，祝你有个美好的一天，Alladinian。 – jxdwinter 2012-03-19 16:32:58

BTW，用新的语言特性，没有必要申报ivars在界面中。如果你已经声明了属性并合成它们，编译器会照顾它们。

@interface NoticeViewController : UIViewController 
<UITableViewDataSource,UITableViewDelegate> 
{  
    NSMutableArray *allNoticeArray; 

    NSArray *addNoticeArray; 

    NSInteger totalNotice; 

    NSInteger pageIndex; 

    UITableView *tableView; 
} 
//... 
@end
