模拟启动选项 [英] Simulate Launch Options

问题描述

在我的 appDelegate 中，当应用程序使用来自ie邮件应用程序的文件启动时，我有一些规范。

in my appDelegate, I have some specifications when the App is launch with a File from i.e. Mail app.

当我启动我的应用程序，一切正常。当我通过邮件从文件启动应用程序时，应用程序崩溃。不幸的是，我无法调试，因为我无法模拟 launchchingOptions 。在这一刻，我建立并运行，然后断开iPad，关闭我的应用程序，然后去邮件等...有没有办法调试？

When I launch my App, everything works normal. When I launch the App via File from Mail, the App crashes. Unfortunately, I am not able to debug it as I can't simulate launchingOptions. at the moment, I build and run, then disconnect the iPad, close my App and then go to mail etc … Is there a way to debug?

Appdelegate 。（$）

Appdelegate.m

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

NSURL *url = (NSURL *)[launchOptions valueForKey:UIApplicationLaunchOptionsURLKey];

IntroViewController *introViewController = (IntroViewController *)self.window.rootViewController;

if (url !=nil) {
    if ([url isFileURL]) {
        introViewController.fileUrl = url;
    }


}

NSLog(@"%@",[url path]);

return YES;
}

IntroViewController

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    NSLog(@"Hello");
    if (fileUrl != nil) {
        IntroTableViewController* introTable = (IntroTableViewController *)segue.destinationViewController;            
        introTable.openedByURL = [fileUrl path];

        TabBarController* tabBarController = (TabBarController *)segue.destinationViewController;
        UINavigationController* navigationController = (UINavigationController *)[[tabBarController viewControllers] objectAtIndex:0];
        TargetLSController* targetViewController = (TargetLSController *)[[navigationController viewControllers] objectAtIndex:0];
        NSString *urlPath = [fileUrl path];
        targetViewController.currentFilePath = urlPath;
        NSLog(@"%@",urlPath);
    }
}

- (void)viewDidAppear:(BOOL)animated
{
    [self performSegueWithIdentifier:@"Launch" sender:self]; 
    NSLog(@"%@",fileUrl);
}

推荐答案

（猜测你使用Xcode 4 .x）

(Guessing you use Xcode 4.x)

产品 - >编辑方案... 和运行< appname> .app 有启动选项（信息）。选择等待< appname.app> 启动。现在当你执行build&运行（或只是运行），调试器将等待您手动启动应用程序。

Product -> Edit Scheme... and under Run <appname>.app there is Launch option in first tab (Info). Select Wait for <appname.app> to launch`. Now when you perform build & run (or just run), debugger will wait for you to launch the app manually.
