表重新加载数据不起作用

Question

在我的应用程序中，五个标签栏正在使用。在第五个标签中有一个表视图在那里im检索和数组并显示在表视图。数组内容在NSLog.But中正确显示只有阵列中的第一个内容显示在单元格中。任何人都可以帮助我如何解决这个问题，请.. 下面是我使用的代码，任何人都可以给我一个手，哪里会出错，请..

这里是其中IM添加内容

-(IBAction)Done 
{ 
NSString *message = [df stringFromDate:itemDate]; 
    NSLog(@"message1234 %@",message); 
dates= [[NSMutableArray alloc] init]; 
      NSUserDefaults *currentDefaults7 = [NSUserDefaults standardUserDefaults]; 
      NSData *dataRepresentingSavedArray7 = [currentDefaults7 objectForKey:@"datingg"]; 
      NSMutableArray *oldSavedArray7 = [NSKeyedUnarchiver unarchiveObjectWithData:dataRepresentingSavedArray7]; 
    if(dates!=nil) 
     { 

      dates = [[NSMutableArray alloc] initWithArray:oldSavedArray7]; 

     } 
     [dates addObject:message]; 
     NSUserDefaults *currentDefaults3 = [NSUserDefaults standardUserDefaults]; 
     [currentDefaults3 setObject:[NSKeyedArchiver archivedDataWithRootObject:dates] forKey:@"datingg"]; 
     [currentDefaults3 synchronize]; 
     NSLog(@"%@dates ate getting heree",dates); 

这里是IM以便在检索内容（第五选项卡）

     datedisplay = [[NSMutableArray alloc] initWithArray:oldSavedArray];

Answer 1

你在告诉你的表只有一行。

(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    return [datedisplay count]; 
} 

而不是你有什么。

Answer 2

取而代之的是

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
//#warning Incomplete method implementation. 
    // Return the number of rows in the section. 
    return 1; 
} 

使用

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
//#warning Incomplete method implementation. 
    // Return the number of rows in the section. 
    return [datedisplay count]; 
}
