Question

在我的应用程序中有五个标签栏正在使用。在第五个标签页中有一个表格视图。我可以检索和排列并在表格视图中显示。数组的内容在NSLog中正确显示。但只有第一个内容在数组正在显示在单元格中。任何人都可以帮我解决这个问题。下面是我使用的代码，任何人都可以帮我一把手，我会出错...

这是我添加内容的地方

-(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);

这是我正在检索内容的地方（第五个标签）

Answer 1

而不是这个

- (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];
}

Answer 2

你告诉你的表它只有一行。

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

而不是你拥有的。

表重新加载数据不起作用
