UISplitViewController, animating views - objective-c

I'm trying to animate my detail view controller to transition with a page curl (up/down). I'm trying to achieve a similar effect as the Notes application on the iPad, this transition was also reproduced by CulturedCode in their Things application for iPad.
My problem is that the animation is clipped to the bounds of the Detail View Controller, it doesn't animate into the Master View Controller, therefore limiting the effect. I see that Apple and CulturedCode managed to make this happen, but I'm stumped.
I've tried the following solutions:
self.splitViewController.view.clipToBounds = False;
self.view.clipToBounds = False;
self.tableView.clipToBounds = False;
The only other solution I can think of is discarding the UISplitViewController altogether and creating my own VC programmatically that will mimic the UISVC behavior so that both of the views (former separate view controllers) will share the same Super View.
Thank you in advance, any advice will help.

A solution it to just set clipsToBounds to NO and bring the details view to the front in it's superview. Like so:
detailsView.clipsToBounds = NO;
[detailsView.superview bringSubviewToFront:detailsView];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:detailsView cache:YES];
...
[UIView commitAnimations];
Where detailsView is your container for the details pane. This should do the trick and the details view will animate in front of the master view. I now have my page transition look quite like the Notes app.

How to make blur effect when view controller slides out

I've got a program with slide out menu. There's Menu button(BarButtonItem) in the right position. When the view controller loads I'm doing next
_menuBarButton.target = self.revealViewController;
_menuBarButton.action = #selector(revealToggle:);
So, when I click on the this button the View Controller slides out to right and I see another View Controller.
So, I want to make the main view controller blur when it slides out. I've got a code how to do it blur, but I can't implement this code because when I tap on the bat button it runs revealToggle: selector.
I've tried:
1. To set action for bar button. And firstly blur view controller:
- (IBAction)menuBarButtonTapped:(UIBarButtonItem *)sender {
[self setBlurEffect];
_menuBarButton.target = self.revealViewController;
_menuBarButton.action = #selector(revealToggle:);
[self.menuBarButton.target performSelector:#selector(revealToggle:)];
}
But app crashes with "unrecognized selector" (the solutions of this problem doesn
t help too).
I've wanted to use willDisapear method but it doesn't run, because the main view controller doesn't disapear. It just slides out.
So, could you help me with this problem?
P.S. I'll be happy if you propose any other effects for main view controller except blur.
P.P.S. Sorry for many mistakes in question.
I've found a good answer for me. I don't use several ViewControllers to implement menu panel.
Now I'm using another UIView calls menuPanel. It contains tableView(UITableView) and blurView(UIView). The second one is under first one.
You can blur this view in to ways:
From the code using next method.
(void) setBlurEffect {// Add blur view
CGRect boundsView = self.someView.bounds;
UIVisualEffectView *tableViewVisualEffect = [[UIVisualEffectView alloc] initWithEffect:[UIBlurEffect effectWithStyle:UIBlurEffectStyleExtraLight]];
self.tableViewVisualEffect.frame = boundsView;
self.tableViewVisualEffect.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
self.tableViewVisualEffect.backgroundColor = [UIColor clearColor];
[UIView transitionWithView:self.view
duration:0.3
options:UIViewAnimationOptionTransitionCrossDissolve
animations: ^ {
[self.someView addSubview:self.tableViewVisualEffect];
}
completion: nil ];
// Here you can add visual effects to any UIView control.
// Replace custom view with navigation bar in above code to add effects to custom view.
}
Where someView is view you want to do blur(or any other effect)
From the story board with Visual Effect View.(I've chosen)
After all I've set tableView and blurView into menuPanelView as pinned to all sides of the menuPanel with 0 distance.
And the last thing I've done I'm changing the position of the menuPanelView with animation:
[self.menuPanelView setFrame:self.visibleTableViewFramePosition];
[UIView animateWithDuration:0.8
animations:^{
[self.menuPanelView setFrame:self.invisibleTableViewFramePosition];
} completion:nil];
Where invisibleTableViewFramePosition is CGRect variable contains position of the menuPanelView when it has to be invisible. You also need to create visibleTableViewFramePosition.
That's all. Hope it may be helpful for someone=)

UIView clipToBounds is not stopping a subView receiving touches outside the parent view

I have two UIViews. I'm using one to contain the other so that I can slide one inside the other. I'm encountering an issue where even though a subView is clipped to the bounds of its parent, it is still receiving touch events and blocking access to other underlying views.
I have three screenshots that show the layout. I've coloured the parent green and the child red.
The idea is that the user clicks "View" and the subView slides up. When the subView is in the default position, the UITabBar is covered and cannot be clicked. You can see this in the first image where the red view is present at the bottom. When the subView is moved to the top, the UITabBar can be clicked as it's now visible. In the third image, I've show what it's like with clipToBounds enabled on the green UIView.
I've enabled clipToBounds, so I cannot understand why the subView is blocking the underlying UITabBar. Is my understanding of clipToBounds completely wrong??
Using clipToBounds only affects the visual layout of a subView, not the logical layout. This means that whilst my subView isn't visible to the eye, it's visible to touch.
I've worked around this issue by animating the size of the subView rather than its position. In my code below, the stationProximityView is the subView. I animate its size by 40 pixels to bring the black title back into view.
[UIView beginAnimations:#"stationProximityBar" context:NULL];
self.stationProximityView.view.frame = CGRectOffset(self.stationProximityView.view.frame, 0, -40);
[UIView commitAnimations];
When I no longer need it, I animate it out of view.
[UIView beginAnimations:#"stationProximityBar" context:NULL];
self.stationProximityView.view.frame = CGRectMake(0 ,0, 320, 500);
[UIView commitAnimations];
If the user taps the view button, the entire subView is shown:
[UIView beginAnimations:#"stationProximityBar" context:NULL];
self.stationProximityView.view.frame = CGRectMake(0,460,320,40);
[UIView commitAnimations];
Dismissal causes the view to be hidden in the same way as the small bar.
[UIView beginAnimations:#"hideStationProximityBar" context:NULL];
self.stationProximityView.view.frame = CGRectMake(0,0,320,500);
[UIView commitAnimations];
At the moment, this code is only being tested on the iPhone 5, so the hard-coded height of 500 would causes issues on previous iPhone models.

Fade UIView and Switch UIView

This is how I switch from one UIView to another UIView: self.view = MyView;
How would I fade out a view to my MySecondView?
You can use UIView's build in transition code to cross dissolve between them.
[UIView transitionFromView:self.view toView:MySecondView duration:0.25 options:UIViewAnimationOptionTransitionCrossDissolve completion:^(BOOL finished) {
// What to do when its finished.
}];
You can also use the regular animation options with something like this. I haven't tested this code as I'm not in front of Xcode but I use it all the time for labels and things without default animations.
[UIView animateWithDuration:0.25 animations:^{
[self.view setAlpha:0.0];
self.view = mySecondView;
[self.view setAlpha:1.0];
}];
Please note that it's not a good idea to do things like self.view = MyView to change screens. By the time you get to a few screens, your viewController will be filled with spaghetti code. You should consider presenting new view controllers that manage their views. One way you can do fade is as follows:
Fade the current view to black (with animation)
In the view controller that you are going to push use viewWillAppear to fade the view to black as well
Push/Present the view controller without animations.
Now use the viewDidAppear method of the newly presented view controller to fade in the view (with animation).

Flip vertical UIWebview to be shown when view did load

I was searching information to show a uiwebview using a flip horizontal effect like modal transition one in viewDidLoad event, but I wasn't successful, even in apple documents. Can anybody help me with that?
Many thanks
the transition to animate webView with the view add your webView like this.
[UIView transitionWithView:poster.view duration:3
options:UIViewAnimationOptionTransitionFlipFromLeft animations:^{
[self.view addSubview:yourWebView];
}
completion:NULL];
The animation you want to add can be done on the UIView. So you should addSubView the UIWebview to the UIView and then do the animation on the UIView.

Hide uiview, but not it's subview?

I have an app where i add ViewB as a subview to ViewA... But the background of ViewB is clearColor, which means that I can see ViewA through ViewB! If I set viewA to be hidden, ViewB goes away too!
I am making a "flip-transition" between the views, so I can't just remove ViewA and then add ViewB :-/
-Anybody got an idea about what I can do?
Here's my code:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight
forView:mainTableView
cache:YES];
[mainTableView addSubview:subTableView];
[UIView commitAnimations];
"I am making a "flip-transition" between the views, so I can't just remove ViewA and then add ViewB :-/ " - actually yes, you can. As a first step, you should add ViewA to the parent view. Later on, when you want to do the flip, you remove ViewA, and add ViewB to the parent view, and you do the flip transition on the parent view.
Hope this helps.
I would recommend that you don't add the back view as a sub ViewB as a subview of ViewA. The best solution would be keeping them separate... The method previously mentioned (transitionFromView:toView:duration:options:completion:) is the correct method to use... just make sure you do not have one as a subview of the other... instead, if ViewA is going to be the "back view" then just do this...
[UIView transitionFromView:viewB toView:viewA options:UIViewAnimationOptionTransitionFlipFromRight completion:NULL];
UIViewAnimationOptionFlipFromRight is just one option... read docs for more options....
Check out the help for setAnimationTransition:forView:cache: - it sounds like you want to change the appearance of a view during a transition, flipping from one view to another, both views visible during the animation? In order to do this the docs suggest using a container view. The docs also suggest in iOS 4.0 and later that you use block-based animation.
Try using transitionFromView:toView:duration:options:completion:
