我有一个表格视图，它从数组中的 xml 加载数据并显示它，每个单元格都指向重新填充的同一个详细视图。

在同一个视图中，我有一个隐藏的地图视图，地图视图在地图中显示相同的表格数组，每个注释都有一个指向表格的相同详细视图的披露按钮，但我不明白我是如何可以将数据从地图视图传递到详细视图...

对于披露按钮，我使用此代码

-(IBAction)showDetails:(id)sender{

DettMercatiViewController *dettMercatiViewController = [[DettMercatiViewController alloc] initWithNibName:@"DettMercatiViewController" bundle:nil];
dettMercatiViewController.mieiMercati = [table objectAtIndex:????];
[self.navigationController pushViewController:dettMercatiViewController animated:YES];
[dettMercatiViewController release]; 

}

table 是从 xml 创建的 nsmutablearray 的名称，但我不知道 objectIndex 使用什么...任何想法？

好的，这里是viewdidload和pin的创建，请帮我解释一下，因为我很冷漠：

    pp =0;

self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:33.0f/255.0f green:89.0f/255.0f blue:50.0f/255.0f alpha:1.0f];

//Font Navigation Bar
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 45)];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont fontWithName:@"Museo700-Regular" size:20];
label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
label.textAlignment = UITextAlignmentCenter;
label.textColor =[UIColor whiteColor];
label.text=[self.title uppercaseString];  
self.navigationItem.titleView = label; 
[label release];

我建议给你的地图视图中的每个披露按钮一个标签，你可以使用这个标签而不是这样

[table objectAtIndex:[sender tag]];
