在 xcode 中从表视​​图到不同的详细视图

Question

我是一名初级程序员。我有一个问题。 我目前在我的应用程序中有一个表格视图。它分为三行，历史、理论和应用用途。我希望每个人都去不同的细节视图。但是，每个人都只点击其中一个详细视图。

我认为问题出在

didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"Magnets_AU_Aubrey" bundle:[

请帮助任何人。三个 XIB 是 Magnets_AU_Aubrey、Magnets_History_Aubrey 和 Magnets_Theory_Aubrey

#import "DisclosureButtonController.h"
#import "NavAppDelegate.h"
#import "DisclosureDetailController.h"
#import "DetailViewController.h"

@implementation DisclosureButtonController
@synthesize list;

- (void)viewDidLoad {
    NSArray *array = [[NSArray alloc] initWithObjects:@"History", @"Theory", @"Applied Use", nil];
    self.list = array;
    [array release];
    [super viewDidLoad];
}

- (void)viewDidUnload {
    self.list = nil;
    [childController release], childController = nil;
}

- (void)dealloc {
    [list release];
    [childController release];
    [super dealloc];
}

NSArray *array = [[NSArray alloc] initWithObjects:@"History", @"Theory", @"Applied Use", nil];

现在对 xibs 做同样的事情。创建数组并用 xib 名称填充它。然后在 didSelectRowAtIndexPath 中获取正确的 xib 名称，应用与在 cellForRowAtIndexPath 中相同的逻辑来获取单元格文本。
