I am trying to make my label appear with animation:
- (void)handleSingleTap:(UIGestureRecognizer *)gestureRecognizer {
if (isShowingRectangleLabel == NO) {
[UIView transitionWithView:rectangleLabel duration:0.5
options:UIViewAnimationOptionTransitionCrossDissolve
animations:^ { [self.view addSubview:rectangleLabel]; }
completion:nil];
NSLog(#"action");
isShowingRectangleLabel = YES;
} else {
[UIView transitionWithView:rectangleLabel duration:0.5
options:UIViewAnimationOptionTransitionFlipFromBottom
animations:^ { [rectangleLabel removeFromSuperview]; }
completion:nil];
isShowingRectangleLabel = NO;
}
}
But this animation works only after second adding to subview. How can I fix it?
EDIT To clarify, addSubview works but without animation.
Do this:
- (void)handleSingleTap:(UIGestureRecognizer *)gestureRecognizer {
if (isShowingRectangleLabel == NO) {
[UIView transitionWithView:self.view duration:0.5
options:UIViewAnimationOptionTransitionCrossDissolve
animations:^ { [self.view addSubview:rectangleLabel]; }
completion:nil];
NSLog(#"action");
isShowingRectangleLabel = YES;
} else {
[UIView transitionWithView:self.view duration:0.5
options:UIViewAnimationOptionTransitionFlipFromBottom
animations:^ { [rectangleLabel removeFromSuperview]; }
completion:nil];
isShowingRectangleLabel = NO;
}
}

I have IBOutlet on bottom of the screen for ADBannerView, and I won't to hide it when it shows white screen (not able to load an Ad).
I have this code, but it is not working:
- (void)bannerViewDidLoadAd:(ADBannerView *)banner
{
[UIView beginAnimations:#"showAd" context:nil];
CGRect adBannerViewFrame = [bannerView frame];
adBannerViewFrame.origin.x = 160;
adBannerViewFrame.origin.y = 523;
bannerView.frame = adBannerViewFrame;
[UIView commitAnimations];
}
- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
[UIView beginAnimations:#"hideAd" context:nil];
CGRect adBannerViewFrame = [bannerView frame];
adBannerViewFrame.origin.x = 0;
adBannerViewFrame.origin.y = 0;
bannerView.frame = adBannerViewFrame;
[UIView commitAnimations];
}
Can you help me please, I'm struggling with it for past two hours... :/
you should try something like this (this is from a live project). the iAd banner is at the bottom of the screen and it goes down when it becomes invisible, and it comes up back when it must be visible.
the _isiADBannerVisible is just a simple Boolean variable.
- (void)bannerViewDidLoadAd:(ADBannerView *)banner {
if (_isiADBannerVisible == false) {
_isiADBannerVisible = true;
[UIView animateWithDuration:0.5f delay:0.f options:UIViewAnimationCurveEaseInOut animations:^{
[banner setFrame:CGRectOffset(banner.frame, 0.f, -50.f)];
} completion:nil];
}
}
- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error {
if (_isiADBannerVisible == true) {
_isiADBannerVisible = false;
[UIView animateWithDuration:0.5f delay:0.f options:UIViewAnimationCurveEaseInOut animations:^{
[banner setFrame:CGRectOffset(banner.frame, 0.f, +50.f)];
} completion:nil];
}
}
I've been trying to minimize all my functions in my app but can't really find how to make this function better, maybe someone is a lot better at this than me? :)
-(void)showRivBoxWithAnimtation:(BOOL)yesno {
if(yesno) {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.2];
if ([self alpha] > 0) {
[self setAlpha:0.0];
[appDelegate.JSONparser setDelegate:self.delegate]; //Give back the JSONparser to the parent!
} else {
[self setAlpha:1.0];
}
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(clearRivBoxContent:finished:context:)];
[UIView commitAnimations];
} else {
if ([self alpha] > 0) {
[self setAlpha:0.0];
[appDelegate.JSONparser setDelegate:self.delegate]; //Give back the JSONparser to the parent!
} else {
[self setAlpha:1.0];
}
}
}
This is what I would do:
-(void)showRivBoxWithAnimtation:(BOOL)yesno {
[UIView animateWithDuration:yesno ? 0.2 : 0.0
animations:^{
if ([self alpha] > 0) {
[self setAlpha:0.0];
[appDelegate.JSONparser setDelegate:self.delegate]; //Give back the JSONparser to the parent!
} else {
[self setAlpha:1.0];
}
}
completion:^(BOOL finished){
if (finished) {
// Do the stuff from clearRivBoxContent:finished:context:
}
}];
}
Unless the order of operations wrt. alpha is critical; this is probably the smallest it can be made.
-(void)showRivBoxWithAnimtation:(BOOL)yesno {
if ([self alpha] > 0) {
[self setAlpha:0.0];
[appDelegate.JSONparser setDelegate:self.delegate]; //Give back the JSONparser to the parent!
} else {
[self setAlpha:1.0];
}
if(yesno) {
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.2];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(clearRivBoxContent:finished:context:)];
[UIView commitAnimations];
}
}
Ha ii every body ,how can we implement a page-curl in tableview,i have a tableview which contains pages of the book and i have implement the touch events in the tableview cell for next chapter and previous chapter,left-swipe for next and right-swipe for previous chapter,when we swipe the tableview it reloads the next chapter and previous chapter content,it really works well but i want it in a page-curl animation,when the user swipe left or right tableview loads content with a page-curl animation.Is that possible to do in a tableview cell?my code for left and right swipe for chapter navigation as follows.
-(void) handleSwipeGesture:(UISwipeGestureRecognizer*)recognizer {
if(![delegate.selectedChapter isEqualToString:[NSString stringWithFormat:#"%d",[DbHandler mNumberOfChaptersInBook:delegate.selectedBook]]]) {
// if the currentChapter is the last then do nothing
delegate.selectedChapter = [NSString stringWithFormat:#"%d",[delegate.selectedChapter intValue] + 1];
[delegate reloadVerses];
[self resetReadViewToVerse:1];
[table removeGestureRecognizer:recognizer];
}
if (recognizer.state==UIGestureRecognizerStateBegan ) {
self.table.scrollEnabled = NO;
}
else if(recognizer.state==UIGestureRecognizerStateEnded) {
self.table.scrollEnabled = YES;
}
return;
}
-(void) handleSwipeGestureleft:(UISwipeGestureRecognizer*)recognizer {
if(![delegate.selectedChapter isEqualToString:#"1"])
{
delegate.selectedChapter = [NSString stringWithFormat:#"%d",[delegate.selectedChapter intValue] - 1];
[delegate reloadVerses];
[self resetReadViewToVerse:1];
[table removeGestureRecognizer:recognizer];
}
if (recognizer.state==UIGestureRecognizerStateBegan ) {
self.table.scrollEnabled = NO;
}
else if(recognizer.state==UIGestureRecognizerStateEnded) {
self.table.scrollEnabled = YES;
}
return;
}
Thanks in advance.
I got the answer.
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.4];
[UIView setAnimationDelay:0.0];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDidStopSelector:#selector(animCompleteHandler:finished:context:)];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES];
[UIView commitAnimations];
just put this code inside the methods.Thanks
I have some classes for watching pictures in gallery. in those classes after enabling ARC i get message that implicit conversion is forbidden by ARC and I cant run the application.
Those methods are:
- (void) curlToPrevious
{
if (currentImageIndex == 0) return;
if ([self.image2 superview] == NO) {
self.image2.image = (UIImage*) [imageViews objectAtIndex:(currentImageIndex-1)];
} else {
self.image1.image = (UIImage*) [imageViews objectAtIndex:(currentImageIndex-1)];
}
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:kTransitionDuration];
currentImageIndex--;
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.containerView cache:YES];
if ([self.image2 superview] == NO) {
[self.image1 removeFromSuperview];
[self.containerView addSubview:self.image2];
} else {
[self.image2 removeFromSuperview];
[self.containerView addSubview:self.image1];
}
[UIView commitAnimations];
[self updateCurrentImageCounter];
}
- (void) curlToNext
{
if (currentImageIndex == ([self imageCount]-1)) return;
if ([self.image2 superview] == NO) {
self.image2.image = (UIImage*) [imageViews objectAtIndex:(currentImageIndex+1)];
} else {
self.image1.image = (UIImage*) [imageViews objectAtIndex:(currentImageIndex+1)];
}
currentImageIndex++;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:kTransitionDuration];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.containerView cache:YES];
if ([self.image2 superview] == NO) {
[self.image1 removeFromSuperview];
[self.containerView addSubview:self.image2];
} else {
[self.image2 removeFromSuperview];
[self.containerView addSubview:self.image1];
}
[UIView commitAnimations];
[self updateCurrentImageCounter];
}
I have
if ([self.image2 superview] == NO) {
In this line on 4 places in code problem.
The text I get is:
implicit conversion of 'int' to 'UIView' is disallowed with ARC
How can I avoid this??? Thanks.
you can replace your code on this if ([self.image2 superview] == nil)
You are comparing an UIView* with an integer (0) - of course you get a warning. Do you want to check whether the superview is nil? Then just do that:
if([self.image2 superview] == nil) { ... }
Right I know how to do the pictue book effect but I struggling to remove the view
So page 1, I add the second page view via addSubview (via a swipe). I also increment a counter so I know what page I am on.
So how do I return to page 1? See I thought it would be self.view removeFromSuperview but that crashes when you try to go back to page 2
Code below
- (void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer {
if (recognizer.direction == UISwipeGestureRecognizerDirectionLeft) {
//NSLog(#"swipe right to left");
UniversalAppAppDelegate *appDelegate = (UniversalAppAppDelegate *)[[UIApplication sharedApplication] delegate];
PictureBookViewController *viewController2 =(PictureBookViewController *) [appDelegate getViewControllerForViewID:#"81"];
[UIView beginAnimations:Nil context:nil];
[UIView setAnimationDuration:0.6];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view.superview cache:YES];
self.viewController = viewController2;
self.viewController.pageNo = self.pageNo + 1;
[self.view addSubview:self.viewController.view];
[UIView commitAnimations];
[viewController2 release];
} else {
//NSLog(#"swipe left to right");
NSLog([NSString stringWithFormat:#"%d", self.pageNo]);
if (self.pageNo > 0) {
[UIView beginAnimations:Nil context:nil];
[UIView setAnimationDuration:0.6];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view.superview cache:YES];
//self.viewController = viewController2;
//self.viewController.pageNo = self.pageNo - 1;
//[self.view addSubview:self.viewController.view];
[self.view removeFromSuperview];
//[self.view addSubview:self.viewController.view];
[UIView commitAnimations];
}
}
}
Update:
Each view has its own view controllers.
You want to remove your viewController's view, not the container's view.
[self.viewController.view removeFromSuperview];
This seems to work and not crash? I am now convinced it right. I just seem to need a way of removing the last added subview. My first view is not the superview
- (void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer {
if (recognizer.direction == UISwipeGestureRecognizerDirectionLeft) {
//NSLog(#"swipe right to left");
UniversalAppAppDelegate *appDelegate = (UniversalAppAppDelegate *)[[UIApplication sharedApplication] delegate];
PictureBookViewController *viewController2 =(PictureBookViewController *) [appDelegate getViewControllerForViewID:#"82"];
[UIView beginAnimations:Nil context:nil];
[UIView setAnimationDuration:0.6];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view.superview cache:YES];
self.viewController = viewController2;
self.viewController.pageNo = self.pageNo + 1;
self.viewController.lastViewController = self;
[self.view addSubview:self.viewController.view];
[UIView commitAnimations];
[viewController2 release];
} else {
//NSLog(#"swipe left to right");
NSLog([NSString stringWithFormat:#"%d", self.pageNo]);
if (self.pageNo > 0) {
[UIView beginAnimations:Nil context:nil];
[UIView setAnimationDuration:0.6];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view.superview cache:YES];
self.pageNo --;
self.view = self.viewController.view;
[self.view removeFromSuperview ];
self.view = self.lastViewController.view;
[UIView commitAnimations];
}
}
}
