iphone - 如何更改 iOS SDK 中的默认导航速度？

Question

我正在从一个 View Controller 导航到另一个 View Controller 。有一个指定的默认时间用于从一个类导航到另一个类。我们能否以编程方式更改该时间，即我们能否提高或降低导航速度。

FlashScreen *Secreen=[[FlashScreen alloc]initWithNibName:nil bundle:nil];
    [self.navigationController pushViewController:Secreen animated:YES];

You need to use a custom animation like seague Animation class file where you can give the Transition duration for moving from one view controller to another view controller

-(void)perform{
    UIViewController *sourceViewController = (UIViewController *) [self sourceViewController];
    UIViewController *destinationViewController = (UIViewController *) [self destinationViewController];
    CATransition* transition = [CATransition animation];
    if ([self.identifier isEqualToString:@"b"]){
        transition.duration = .25;
        transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
        transition.type = kCATransitionMoveIn; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
        transition.subtype = kCATransitionFromLeft; //kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom
    }else{
        transition.duration = .25;
        transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
        transition.type = kCATransitionMoveIn;
        transition.subtype = kCATransitionFromRight;
    }
    [sourceViewController.navigationController.view.layer addAnimation:transition
                                                            forKey:kCATransition];
    [sourceViewController.navigationController pushViewController:destinationViewController animated:NO];
}
