I am having four ViewControllers , where the ViewControllers are loaded using the UINavigationController. I am able to switch to every ViewController one by one.
The thing is, since I am using the NavigationController all the ViewControllers are loaded either from the Left or from the Right. But I want to load the ViewController from the Bottom. I know I can use presentModalViewController to present the ViewController from the Bottom. But it is not equivalent to the Navigation Controller because , from the 4th ViewController, If I press one button , I need to come to the 1st ViewController.
How can I present a ViewController from the bottom in the NavigationController ?
Try this:
CATransition *animation = [CATransition animation];
[animation setDuration:2];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromTop];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
SecondView *sObj=[[SecondView alloc] initWithNibName:#"SecondView" bundle:nil];
[self.navigationController pushViewController:sObj animated:YES];
[[sObj.view layer] addAnimation:animation forKey:#"SwitchToView1"];
Use this may this will help you
[UIView beginAnimations:#"Hide Me" context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:kAnimationDur];
subScroll.frame = CGRectMake(0,ksubScrollHideY,ksubScrollW,ksubScrollH);
clickPic.frame = CGRectMake(kButtonX,kButtonHiddenY,kButtonW,kButtonH);
[UIView setAnimationDelegate:self];
[UIView commitAnimations];
Happy Coding :)
after you create the viewController, instead of:
[self.navigationController pushViewController:blablabla animated:YES];
do:
[self presentModalViewController:blablabla animated:YES];
and it will come from the bottom.
to go back, just say:
[self dismissViewControllerAnimated:YES];

Right now I am using a segue from storyboard to push a view controller and there is just the one push transition. How can I imitate the "Pop" transition in code? Can I do this while still using storyboard for my other transitions in place now?
UPDATE
I tried what is suggested in the first comment here, with some changes. Here's what I have:
UIViewController *dst = [self destinationViewController];
UIViewController *src = [self sourceViewController];
[dst viewWillAppear:YES];
[dst viewDidAppear:NO];
CGRect screenBounds = [[UIScreen mainScreen] bounds];
CGRect f = CGRectMake(-screenBounds.size.width, 0, screenBounds.size.width, screenBounds.size.height);
dst.view.frame = f;
f.origin.x = screenBounds.size.width;
src.view.frame = f;
[UIView transitionFromView:src.view
toView:dst.view
duration:0.3
options:UIViewAnimationOptionTransitionNone
completion:^(BOOL finished){
[dst viewDidAppear:YES];
UINavigationController *nav = src.navigationController;
[nav popViewControllerAnimated:NO];
[nav pushViewController:dst animated:NO];
}];
This is working almost how I want, but the original viewcontroller is just disappearing instead of sliding to the right.
You can create Segue type "Custom" on your stroyboard and create a new UIStoryboardSegue class named "popSegue" In the popSegue.m file add this:
-(void)perform{
UIViewController *sourceViewContreoller = [self sourceViewController];
CATransition *animation = [CATransition animation];
[animation setType:kCATransitionFromLeft]; //or kCATransitionFromRight
[animation setDuration:0.25];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:
kCAMediaTimingFunctionEaseIn]];
[sourceViewContreoller.navigationController.view.layer addAnimation:animation forKey:#"animateOpacity"]; //or key=#"fadeTransition"
[sourceViewContreoller.navigationController popViewControllerAnimated:YES];
[CATransaction commit];
}
In the storyboard editor Select the segue and change the Segue Class to "popSegue".
Set the Identifier to "popSegue".
Try this and comment for your result
anyone know how to implement something like a viewController no full screen just like when we tap in search in the iPhone ?
I want that when the user make an swipe up a viewController (half height) be showed.
No segue !! I would like that the old view controller be showed at the same time.
Thanks in advance
I Add this type of functionality for whole project, i add the QRView in window so user swip up the view from any view of project...
See the Example of my code..
Just set the UISwipeGestureRecognizer to your second view which you want to present like bellow...
CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setType:kCATransitionFade];
[animation setDuration:0.5];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:
kCAMediaTimingFunctionEaseInEaseOut]];
[[self.view layer] addAnimation:animation forKey:kAnimationKey];
UISwipeGestureRecognizer *swipeGesture = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(addCustomBottomBar)] autorelease];
swipeGesture.numberOfTouchesRequired = 1;
swipeGesture.direction = (UISwipeGestureRecognizerDirectionDown);
[yourViewController.view addGestureRecognizer:swipeGesture];/// use your view name here, its depends on your requirement
UISwipeGestureRecognizer *swipeGestureTop = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:#selector(addCustomBottomBar)] autorelease];
swipeGestureTop.numberOfTouchesRequired = 1;
swipeGestureTop.direction = (UISwipeGestureRecognizerDirectionUp);
[yourViewController.view addGestureRecognizer:swipeGestureTop];
and this bellow method called when you swipe up view...
Also just add one BOOL variable with name isViewPop and set it to NO in your viewDidLoad: method ..
-(void)addCustomBottomBar{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.window cache:YES];
if (isqrcodepop) {
isViewPop=NO;
yourViewController.view.frame=CGRectMake(0, 430, 320, 70);
}
else{
isViewPop=YES;
yourViewController.view.frame=CGRectMake(0, 210, 320, 270);
[self.view bringSubviewToFront:yourViewController.view];
}
[UIView commitAnimations];
}
i hope this answer helpful for you...
If it is something simple I would add a UIView to your UIViewController just below the bottom-- then when you hit 'Search' or whatever, animate that UIView up in view with an animation block:
- (IBAction)btnTouch:(id)sender
{
[UIView animateWithDuration:0.3
delay:0.0
options: UIViewAnimationCurveEaseInOut
animations:^{
//bring searchView up
_searchView.transform = CGAffineTransformMakeTranslation(0, -80);
}
completion:^(BOOL finished){
}
];
}
Then when you are done, push the view back to its origin by using the same animation block with this line instead:
_searchView.transform = CGAffineTransformMakeTranslation(0, 0);
You could have the background view controller [self presentViewController:vc animated:YES completion:nil]; and set your front view controller's frame to half of the screen. This way, since bottom half of the front view is transparent, your background view controller will still be visible
- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
This function load a view from right side. How can I Load a view from left side?
Here it is
CATransition *animation = [CATransition animation];
[[self navigationController] pushViewController:elementController animated:NO];
[animation setDuration:0.45];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromLeft];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]];
[[elementController.view layer] addAnimation:animation forKey:#"SwitchToView1"];
For this you have to #import <QuartzCore/QuartzCore.h>
don't think there is a readymade way to do that. You will have to animate the view yourself using animateWithDuration:delay:options:animations:completion: or animateWithDuration:animations:completion: (or any other animation methods) and change frames of your view accordingly so that it animates from the right side.
Hope this helps :)
if you already been pushed to a viewController you can use this:
[self.navigationController popViewControllerAnimated:YES]
I am trying to have a UIView slide up a quarter of the page to reveal another view underneath it (to display options), and then slide back down to cover those options. I've searched SO relentlessly but can't seem to find what I'm looking for. I do not want to use a modalview as I want to maintain the top view on the screen. In the code below, I have it sort-of working, the top level slides up, but then completely disappears (fades) out.
Any help is greatly appreciated!
Thanks.
HomeOptionsViewController *homeOptionsViewController = [[HomeOptionsViewController alloc]
initWithNibName:#"HomeOptionsViewController"
bundle:nil];
// get the view that's currently showing
UIView *currentView = self.view;
// get the the underlying UIWindow, or the view containing the current view
UIView *theWindow = [currentView superview];
UIView *newView = homeOptionsViewController.view;
//newView.frame = CGRectMake(0,300, 320,140);
newView.frame = CGRectMake(0,-10, 320,140);
// remove the current view and replace with myView1
//---[currentView removeFromSuperview];
[theWindow addSubview:newView];
theWindow.frame = CGRectMake(0,-110,320,200);
newView.frame = theWindow.bounds;
// set up an animation for the transition between the views
CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromTop];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
//[theWindow setFrame:CGRectMake(0,200,320,300)];
[[theWindow layer] addAnimation:animation forKey:#"SwitchToView1"];
Any reason why you're not using standard UIView animations? CATransitions will entirely change the view because its supposed to be a transition from one view to the other.
Have you tried something like this? You add the view you want to slide just off the bottom of the screen, then animate both frames changing. It creates a slide up effect.
newView.frame = CGRectMake(0,416,320,140);
[theWindow addSubview:newView];
[UIView beginAnimations:#"SwitchToView1" context:nil];
[UIView setAnimationDuration:0.5];
theWindow.frame = CGRectOffset(theWindow.frame, 0, -140);
newView.frame = CGRectOffset(newView.frame, 0, -140);
[UIView commitAnimations];
I am using the following code to switch between views with CATransition.
CATransition *applicationLoadViewIn = [CATransition animation];
[applicationLoadViewIn setDuration:20];
[applicationLoadViewIn setType:kCATransitionPush];
[applicationLoadViewIn setSubtype:kCATransitionFromTop];
[applicationLoadViewIn setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]];
ViewToSwitchTo *myviewcontroller = [[ViewToSwitchTo alloc] init];
[self.view.layer addAnimation:applicationLoadViewIn forKey:kCATransitionPush];
[self.view addSubview:myviewcontroller.view];
It functions mostly how I want it to. It pushes from the top like it should, however it for some reason acts strangely. First, the view I am switching to starts coming in from the bottom like it should, but for some reason, the view that I am switching FROM appears over the top of it with low opacity, so you see both of them. However, you also see the view that is coming in, shifted maybe 100 pixels upwards, on top of itself and the other view, once again with low opacity. Just before the halfway point of the the transition, everything works fine, you only see the view that is coming in and the view going out, doing what they should be doing. But slightly after the halfway point, the view I am switching to appears in its final destination, under the view I am switching from, and the view I am switching from has been reduced in opacity.
What is going on here?
I really not understand what you want but hope this code will help to implement ,if not then tell more about you CATransition
-(void) startAnimation {
fullImageView.alpha = 0.50;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:2.0];
[UIView setAnimationRepeatCount:1];
[UIView setAnimationRepeatAutoreverses:NO];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(pulseAnimationDidStop:finished:context:)];
fullImageView.alpha = 1.0;
[UIView commitAnimations];
}
- (void)pulseAnimationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context {
if(hasFocus) {
[self startAnimation];
} else {
fullImageView.alpha = 1.0;
}
}
-(void) setHasFocus:(BOOL)_hasFocus {
hasFocus = _hasFocus;
if(hasFocus) {
[self startAnimation];
}
}
You can use this way as well
CATransition *applicationLoadViewIn = [CATransition animation];
[applicationLoadViewIn setDuration:1.5];
[applicationLoadViewIn setType:kCATransitionPush];
[applicationLoadViewIn setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn]];
//[applicationLoadViewIn setRepeatCount:114];
productVC=[[PoductViewController alloc]initWithNibName:#"PoductViewController" bundle:[NSBundle mainBundle]];
[[productVC.view layer] addAnimation:applicationLoadViewIn forKey:kCATransitionPush];
[self.view addSubview:productVC.view];
But I suggest you to use Navigation Controller in place of
[self.view addSubview:productVC.view];
just use
[self.navigationController pushViewController:productVC animated:YES];
If you use this, there will be no background view, you will see white screen of the present view. But if you add subview, then you need to manually remove subview.
