I want to do a save image function, after the success of the pop-up tips. When I press the picture pop-up alertController, save the success did not see the prompt box displayed on the keywindow, what is going on ?
//show the tip of suceess
-(void)show{
UIWindow * window =[UIApplication sharedApplication].keyWindow;
[window addSubview:self];
[self mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.equalTo(window.mas_top);
make.leading.equalTo(window.mas_leading);
make.trailing.equalTo(window.mas_trailing);
make.bottom.equalTo(window.mas_bottom);
}];
[self layoutIfNeeded];
self.alpha = 0;
[UIView animateWithDuration:.2 animations:^{
self.alpha = 1;
}];
_alertView.transform = CGAffineTransformMakeScale(0.1, 0.1);
[UIView animateWithDuration:0.3 delay:0.0 usingSpringWithDamping:0.7 initialSpringVelocity:1 options:UIViewAnimationOptionCurveEaseOut animations:^{
_alertView.alpha=1.0;
_alertView.transform = CGAffineTransformIdentity;
} completion:^(BOOL finished) {
}];
}
Try this
// Delay execution of my block for 10 seconds.
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, 10 * NSEC_PER_SEC), dispatch_get_main_queue(), ^{
UIView * windowView =[UIApplication sharedApplication].keyWindow.rootViewController.view;
[windowView addSubview:self];
});

Im trying to fade in and out of a light node I have created I just dont know where to call the function accordingly so it will continously fade in and out. Never tried animating anything here is what I have.
- (void)fadeOutIn:(UIView *)view duration:(NSTimeInterval)duration
{
[self enumerateChildNodesWithName:#"//*" usingBlock:^(SKNode *node, BOOL *stop) {
if ([node.name isEqualToString:#"light1"]) {
[UIView animateKeyframesWithDuration:5 delay:2 options:UIViewAnimationOptionRepeat|UIViewAnimationOptionAutoreverse|UIViewAnimationCurveEaseInOut animations:^{
node.alpha = 0;
} completion:^(BOOL finished) {
}];
}
}];
}
where should I call this function?that is fades in and out continously?
Should it be called within an action?
Thank You
Use this for Continue fade in out.
-(void)viewDidAppear:(BOOL)animated{
[UIView animateKeyframesWithDuration:1 delay:0 options:UIViewAnimationOptionRepeat|UIViewAnimationOptionAutoreverse|UIViewAnimationCurveEaseInOut|UIViewAnimationOptionAllowUserInteraction animations:^{
node.alpha = 0;
} completion:^(BOOL finished) {
[UIView animateWithDuration:1 animations:^{
node.alpha = 1;
} completion:nil];
}];
}
-(void) viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[objAnimate setAlpha:1.0];
[UIView animateKeyframesWithDuration:2.0 delay:0.0 options:UIViewKeyframeAnimationOptionCalculationModeLinear | UIViewAnimationOptionCurveEaseInOut|UIViewAnimationOptionRepeat|UIViewAnimationOptionAutoreverse animations:^{
[objAnimate setAlpha:0.0];
} completion:nil];
}
This will create continuous fade in and out for your object when it appears. If you want to create programmatically a custom object and then use this code then do it after your custom object is added in your view as below (example):
objAnimate = [[UILabel alloc] initWithFrame:CGRectMake(20, 50, 200, 40)];
objAnimate.backgroundColor = [UIColor lightGrayColor];
[objAnimate setAlpha:1.0];
[self.view addSubview:objAnimate];
[UIView animateKeyframesWithDuration:2.0 delay:0.0 options:UIViewKeyframeAnimationOptionCalculationModeLinear | UIViewAnimationOptionCurveEaseInOut|UIViewAnimationOptionRepeat|UIViewAnimationOptionAutoreverse animations:^{
[objAnimate setAlpha:0.0];
} completion:nil];
The view starts animating as soon as its added in your view.
I am popping the couponDetailsView with bounce animation. But i want to dismiss the view from left to right animation. How can i do this? Below is my source code. Any kind of help would be really helpful.
#pragma mark Bounce Animation
-(void) openContentDetailsView
{
[self.view bringSubviewToFront:self.couponDetailsView];
[UIView animateWithDuration:0.2 animations:
^(void){
self.couponDetailsView.transform = CGAffineTransformScale(CGAffineTransformIdentity,1.1f, 1.1f);
self.couponDetailsView.alpha = 0.5;
}
completion:^(BOOL finished){
[self bounceOutAnimationStoped];
}];
}
- (void)bounceOutAnimationStoped
{
[UIView animateWithDuration:0.1 animations:
^(void){
self.couponDetailsView.transform = CGAffineTransformScale(CGAffineTransformIdentity,0.9, 0.9);
self.couponDetailsView.alpha = 0.8;
}
completion:^(BOOL finished){
[self bounceInAnimationStoped];
}];
}
- (void)bounceInAnimationStoped
{
[UIView animateWithDuration:0.1 animations:
^(void){
self.couponDetailsView.transform = CGAffineTransformScale(CGAffineTransformIdentity,1, 1);
self.couponDetailsView.alpha = 1.0;
}
completion:^(BOOL finished){
[self animationStoped];
}];
}
- (void)animationStoped
{
}
- (IBAction)contentDetailsCloseButtonAction:(id)sender {
self.couponDetailsView.alpha = 0;
self.couponDetailsView.transform = CGAffineTransformScale(CGAffineTransformIdentity,0.6, 0.6);
}
Try this:
[UIView animateWithDuration:0.3f
delay:0.0f
options:UIViewAnimationOptionRepeat | UIViewAnimationOptionAutoreverse
animations:^{
[testView setFrame:CGRectMake(x, y, width, height)];
} completion:^(BOOL finished) {
[testView removeFromSuperview];
}];
I am trying to flip transition on the same ViewController, I have a button for trigger transition. I want to change theme color when i press to button via flip transition.
i used this code part:
- (IBAction)changeThemeButtonTapped:(id)sender
{
int tempThemeColor = [[NSUserDefaults standardUserDefaults]integerForKey:#"themeColor"];
if (tempThemeColor == 10) {
[self loadTheme];
[UIView transitionFromView:self.view
toView:self.view
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromLeft
completion:^(BOOL finished) {
NSLog(#"finished");
}];
}else{
[self loadTheme];
[UIView transitionFromView:self.view
toView:self.view
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromRight
completion:^(BOOL finished) {
NSLog(#"finished");
}];
}
}
when i press to button, view turns to black. Is there any way to do? What is my mistake?
Thank you for your answer and interest.
I found my question's answer.
if (tempThemeColor == 10) {
[self loadTheme];
[UIView transitionWithView:self.view
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromLeft
animations:^{
} completion:^(BOOL finished) {
}];
}else{
[self loadTheme];
[UIView transitionWithView:self.view
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromRight
animations:^{
} completion:^(BOOL finished) {
}];
}
Before doing animation try to change the window/super view of the view's color
if (self.view.superview) {
self.view.superview.backgroundColor = [UIColor whiteColor];
}
self.view.window.backgroundColor = [UIColor whiteColor];
I have buttons on some viewController view. touchUpInside: methods present modal view controllers. I want to present them from center of tapped button frame. How can I achieve this result?
I tried:
webController.view.transform = CGAffineTransformScale(CGAffineTransformIdentity, self.buuton.center.x, self.button.center.y);
[self presentViewController:webController animated:NO completion:^{
// some code
}];
but it damaged my UI. I also tried to use [UIView beginAnimation], no success.
I have achieved something similar with a trick, adding destvc.view as subview to sourcevc.view, see below my functions to scale in and scale out.
You can use the same trick only as visual effect, and present your vc at the end, without animation:
+(void) animWithAlpha:(float)alpha view:(UIView*)view{
[UIView animateWithDuration:0.15
delay:0.0
options:UIViewAnimationOptionBeginFromCurrentState
animations:^{
view.alpha = alpha;
}
completion:^(BOOL fin) {}];
}
+(void) zoomIN:(UIViewController*)sourceViewController destination:(UIViewController*)destinationViewController fromPoint:(CGPoint)point{
[sourceViewController.view addSubview:destinationViewController.view];
[destinationViewController.view setFrame:sourceViewController.view.window.frame];
[destinationViewController.view setTransform:CGAffineTransformMakeScale(0.15, 0.1)];
destinationViewController.view.center = point;
sourceViewController.view.userInteractionEnabled=NO;
destinationViewController.view.alpha = 0.5;
[self animWithAlpha:1 view:destinationViewController.view];
[UIView animateWithDuration:0.4
delay:0.0
options:UIViewAnimationOptionCurveEaseInOut
animations:^{
[destinationViewController.view setTransform:CGAffineTransformMakeScale(1, 1)];
destinationViewController.view.center = sourceViewController.view.center;
}
completion:^(BOOL finished){
if(finished){
[destinationViewController.view setTransform:CGAffineTransformMakeScale(1, 1)];
destinationViewController.view.center = sourceViewController.view.center;
sourceViewController.view.userInteractionEnabled=YES;
}
}];
}
+(void) zoomOUT:(UIViewController*)sourceViewController destination:(UIView*)destination toPoint:(CGPoint)point{
[sourceViewController.view setTransform:CGAffineTransformMakeScale(1.0, 1.0)];
[sourceViewController.parentViewController.view setUserInteractionEnabled:NO];
[destination setUserInteractionEnabled:NO];
[UIView animateWithDuration:0.4
delay:0.0
options:UIViewAnimationOptionCurveEaseOut
animations:^{
[sourceViewController.view setTransform:CGAffineTransformMakeScale(0.01, 0.01)];
[sourceViewController.view setAlpha:1.0];
sourceViewController.view.center = point;
}
completion:^(BOOL finished){
if(finished){
[sourceViewController.view setTransform:CGAffineTransformMakeScale(1.0, 1.0)];
[sourceViewController.view removeFromSuperview];
sourceViewController.view.center = point;
[destination setUserInteractionEnabled:YES];
}
}
You have to do that through addSubview: method and doing something like:
- (void) appear: (UIView *) view fromPoint: (CGPoint) point
{
[view setBounds:self.view.bounds];
[view setCenter:point];
[view setAlpha:0.0];
[self addSubview:view];
[view setTransform:CGAffineTransformMakeScale(0, 0)];
[UIView animateWithDuration:0.3 animations:^{
[view setCenter:self.view.center];
[view setTransform:CGAffineTransformIdentity];
[view setAlpha:1.0];
}];
}
You have to create the view before call the method.
Good Luck!
I'm trying to hide a UITabBarController and UINavigationController simultaneously when a button is touch. I found a very nice code snippet here How to hide uitabbarcontroller but I have problem when trying to hide and animate both UINavigationController and the tabbarcontroller. I also found a lot of examples on the internet when they hide the tabbar using self.tabBarController.tabBar.hidden = YES but that only hides the button items not the black bar at the bottom.
After playing a lot around I can get to make both animate correctly because I think that it's related to the hiding of the Navigation Controller which makes the size of the whole window to change on the fly.
-(IBAction)touchImage:(id)sender {
if (isImageFullScreen) {
isImageFullScreen = NO;
[self.navigationController setNavigationBarHidden:NO animated:YES];
[UIView transitionWithView:self.view
duration:0.5
options:UIViewAnimationOptionCurveLinear
animations:^
{
hotelImageButton.frame = CGRectMake(0,20,320,92);
[self showTabBar:self.tabBarController];
}
completion:^(BOOL finished)
{
}];
} else {
isImageFullScreen = YES;
[self.navigationController setNavigationBarHidden:YES animated:YES];
[UIView transitionWithView:self.view
duration:0.5
options:UIViewAnimationOptionCurveLinear
animations:^
{
hotelImageButton.frame = CGRectMake(0,0,320,480);
[self hideTabBar:self.tabBarController];
}
completion:^(BOOL finished)
{
}];
}
}
The hideTabBar and showTabBar methods are the ones from the other post I linked above.
I also tried some other combinations but I can't make it look good. Any ideas?
Thanks in advance.
I tried that code now and I see that the UITabBar show animation doesn't take place smoothly.
I managed to make it smoother by adjusting the duration period for the tabbar showing animation to be lower.
[UIView setAnimationDuration:0.2];
Hopefully that works.
EDIT:
Please try this code, it resizes the parent view to be bigger in 1 animation transaction in such a way that only the bars are hidden and the content is shown.
- (IBAction)TestButton1:(UIButton *)sender {
if(!isAnimating){
if(isTabBarAndNavBarHidden){
[UIView transitionWithView:self.view
duration:0.5
options:UIViewAnimationOptionTransitionNone
animations:^
{
isAnimating=YES;
CGFloat statusBar_height=[[UIApplication sharedApplication] statusBarFrame].size.height;
CGFloat screen_height=[UIScreen mainScreen].bounds.size.height;
[self.tabBarController.view setFrame:CGRectMake(self.tabBarController.view.frame.origin.x, 0, self.tabBarController.view.frame.size.width, screen_height)];
[self.navigationController.navigationBar setFrame:CGRectMake(self.navigationController.navigationBar.frame.origin.x, statusBar_height, self.navigationController.navigationBar.frame.size.width, self.navigationController.navigationBar.frame.size.height)];
}
completion:^(BOOL finished)
{
isTabBarAndNavBarHidden=NO;
isAnimating=NO;
}];
}else{
[UIView transitionWithView:self.view

animations:^
{
isAnimating=YES;
CGFloat statusBar_height=[[UIApplication sharedApplication] statusBarFrame].size.height;
CGFloat screen_height=[UIScreen mainScreen].bounds.size.height;
[self.tabBarController.view setFrame:CGRectMake(self.tabBarController.view.frame.origin.x, statusBar_height-self.navigationController.navigationBar.frame.size.height, self.tabBarController.view.frame.size.width, screen_height+self.navigationController.navigationBar.frame.size.height+self.tabBarController.tabBar.frame.size.height-statusBar_height)];
[self.navigationController.navigationBar setFrame:CGRectMake(self.navigationController.navigationBar.frame.origin.x, 0, self.navigationController.navigationBar.frame.size.width, self.navigationController.navigationBar.frame.size.height)];
}
completion:^(BOOL finished)
{
isTabBarAndNavBarHidden=YES;
isAnimating=NO;
}];
}
}
}
