How to perform segue with no transition animation
提问by voromax
I have an application which starts with a navigation controller. This navigation controller can open modal view controller:
我有一个以导航控制器开头的应用程序。这个导航控制器可以打开模态视图控制器：
- (void)openModalController:(id)sender
{
[self performSegueWithIdentifier:@"SegueIdentifier"];
}
But when the user opens an application using url scheme, I'd like to present the application with the modal controller opened. So I added some methods and tried:
但是当用户使用 url 方案打开应用程序时，我想在打开模态控制器的情况下显示应用程序。所以我添加了一些方法并尝试：
// Controller
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated]; // animated == NO in initial loading
if (_shouldOpenModalController) {
[self openModalController:nil];
}
}
- (void)setShouldOpenModalController:(BOOL)flag
{
_shouldOpenModalController = flag;
}
// AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
if (launchOptions) {
UINavigationController *nc = (UINavigationController *)self.window.rootViewController;
MyViewController *c = (MyViewController *)[ns topViewController];
[c setShouldOpenModalController];
}
}
But here is a problem: the openModalController:performs segue with transition animation I setup in storyboard. How can it be done with no animation? Is there another approach for this task?
但这里有一个问题：openModalController:我在故事板中设置了带有过渡动画的执行转场。没有动画怎么能做到呢？这项任务还有另一种方法吗？

Duplicate your segue in Storyboard and give the second one a different ID.
在 Storyboard 中复制您的 segue 并为第二个指定不同的 ID。
You can then change the transition in the new version.
然后，您可以在新版本中更改过渡。

I am using this snippet to request authorization in viewDidLoad:
我正在使用此代码段请求授权viewDidLoad：
[UIView setAnimationsEnabled:NO];
self.view.hidden = YES;
[self performSegueWithIdentifier:@"segue_auth" sender:self];
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.4 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[UIView setAnimationsEnabled:YES];
self.view.hidden = NO;
});
When authorized, back transition is animated as I want.
获得授权后，后退过渡按我的需要进行动画处理。

One more way we can
我们可以的另一种方式
YourViewController *aYourViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"aYourViewControllerIdentifier"];
[self.navigationController pushViewController:aYourViewController animated:NO];
and add the @"aYourViewControllerIdentifier"to view controller in your storyboard.
并@"aYourViewControllerIdentifier"在故事板中添加查看控制器。
