如何使用Xib文件创建UIViewController？ [英] How do I create UIViewController using Xib-file?

问题描述

很抱歉，如果这个问题已经得到解答，但我找不到答案。

Sorry if this question has already been answered but I can't find an answer.

我正在创建一个应用程序，其中我有一个UITableViewController，当选择单元格右侧的附件按钮，应创建一个包含在.xib文件中找到的接口的UIViewController的新实例。然后，新的UIViewController将被推送到堆栈并显示。
我的问题是如何从现有的.xib文件创建新的UIViewController？

I'm creating an app in which I have an UITableViewController and when the accessorybutton in the right side of a cell is selected a new instance of a UIViewController should be created containing the interface found in a .xib-file. The new UIViewController will then be pushed on to the stack and displayed. My question is how do I create the new UIViewController from an existing .xib-file?

这是我到目前为止所尝试的：
在Xcode：File - > New File - > Cocoa Touch Class - > UIViewController subClass。
复选框UITableViewController子类未选中。
复选框使用XIB进行用户界面选中。

This is what I have tried so far: In Xcode: File -> New File -> Cocoa Touch Class -> UIViewController subClass. Checkbox "UITableViewController subclass" unchecked. Checkbox "With XIB for user interface" checked.

这将创建.m，.h和.xib文件。我在.xib文件的视图中创建了一个用户界面。在界面构建器中选择文件所有者会在类标识中显示新创建的UIViewController。

This creates a .m, a .h and a .xib file. I created a user interface in the "view" in the .xib-file. Selecting "File's owner" in interface builder shows the newly created UIViewController in "Class Identity".

一些代码：

在DetailViewController.m（新的UIViewController）中：

In DetailViewController.m (the new UIViewController):

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
     self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
     return self;
}

在SubViewController.m（旧的UITableViewController）中：

In SubViewController.m (the old UITableViewController):

-(void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath{
     DetailViewController *detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
     //Exception thrown at line below
     [self.navigationController pushViewController:detailViewController animated:YES];
     [detailViewController release];
}

忘记提及.xib文件的名称是DetailViewController.xib 。

Forgot to mention that the .xib-file's name is "DetailViewController.xib".

代码编译正常，但是当我在模拟器中运行它并按下一个附件按钮时，它会因未捕获的异常而终止。

The code compiles fine but when I run it in the simulator and press an accessorybutton it terminates due to uncaught exception.

我缺少什么？

提前致谢

推荐答案

错误出现在我试图显示的新视图中。在.xib文件中，我插入了一个MKMapView，当我删除它时，一切都运行良好。

The error was in the new view I was trying to display. In the .xib-file I had inserted a MKMapView and when I removed this it all works perfectly.

再次感谢您帮我调试！
