在我appDelegate的 IE 邮件应用程序中使用文件启动应用程序时，我有一些规范。
当我启动我的应用程序时，一切正常。当我通过邮件中的文件启动应用程序时，应用程序崩溃。不幸的是，我无法调试它，因为我无法模拟launchingOptions. 目前，我构建并运行，然后断开iPad，关闭我的应用程序，然后转到邮件等......有没有办法调试？
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;
}
介绍视图控制器
- (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);
}
