I am using ShakingAlertView in my app.
https://github.com/lukestringer90/ShakingAlertView
It works perfectly in IOS 6. But after i updating to IOS 7 it didnt animate and the block function for incorrect handing not being called.
Given below is the code for the initialization of shaking alert view.
currentPass = [[ShakingAlertView alloc]initWithAlertTitle:#"Enter Current Password" checkForPassword:self.pass
usingHashingTechnique:HashTechniqueMD5
onCorrectPassword:^{
isCurrentPassConfirmed = YES;
[self._accountSource willScrollToTop];
self.password.text = #"";
[self.password becomeFirstResponder];
} onDismissalWithoutPassword:^{
//NSLog(#"hi");
[self showFailedPasswordAlert];
}];
currentPass.alertViewStyle = UIAlertViewStyleSecureTextInput;
[currentPass show];
Below is the method to animate for shake effect.This is invoked correctly but there is no effect.
- (void)animateIncorrectPassword {
// Clear the password field
_passwordField.text = nil;
// Animate the alert to show that the entered string was wrong
// "Shakes" similar to OS X login screen
CGAffineTransform moveRight = CGAffineTransformTranslate(CGAffineTransformIdentity, 20, 0);
CGAffineTransform moveLeft = CGAffineTransformTranslate(CGAffineTransformIdentity, -20, 0);
CGAffineTransform resetTransform = CGAffineTransformTranslate(CGAffineTransformIdentity, 0, 0);
[UIView animateWithDuration:0.1 animations:^{
// Translate left
self.transform = moveLeft;
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.1 animations:^{
// Translate right
self.transform = moveRight;
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.1 animations:^{
// Translate left
self.transform = moveLeft;
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.1 animations:^{
// Translate to origin
self.transform = resetTransform;
}];
}];
}];
}];
}
Please help me.
iOS7 does not allow you to customize the UIAlertview.
Better create the custom view subclass of UIView which is draw the
view programmatically using - (void)drawRect:(CGRect)rect method.
And create one more container class(inherited from NSObject) which
is used to create and bind your title/password and OK buttons
with your custom delegate property into your customized alert
view.So that we can implement our custom delegate method as like
clickedButtonAtIndex method.
Upto my knowledge there is no changes in block/animation in iOS7.
Or refer this link https://github.com/wimagguc/ios-custom-alertview
The layout of UIAlertView changed drastically is iOS 7, making it almost impossible to customise and alter. You're going to have to come up with a new solution.

I've scrollview with page control and I want to make the subview of my scrollview fadeIn/fadeOut when I scroll to or from the next page. I found that I can use contentOffset to make this effect but I couldn't make it.
In fact, I'm newbie and I wish If there is any tutorial that can help. thank you.
Assuming you hold an array of your view controllers in self.viewControllers indexed according to the UIPageControl:
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
CGFloat diffFromCenter = ABS(scrollView.contentOffset.x - (self.pageControl.currentPage)*self.view.frame.size.width);
CGFloat currentPageAlpha = 1.0 - diffFromCenter/self.view.frame.size.width;
CGFloat sidePagesAlpha = diffFromCenter/self.view.frame.size.width;
//NSLog(#"%f",currentPageAlpha);
[[[self.viewControllers objectAtIndex:self.pageControl.currentPage] view] setAlpha:currentPageAlpha];
if (self.pageControl.currentPage > 0)
[[[self.viewControllers objectAtIndex:self.pageControl.currentPage-1] view] setAlpha:sidePagesAlpha];
if (self.pageControl.currentPage < [self.viewControllers count]-1)
[[[self.viewControllers objectAtIndex:self.pageControl.currentPage+1] view] setAlpha:sidePagesAlpha];
}
You might check out this tutorial on view animation:
Uiview-tutorial-for-ios-how-to-use-uiview-animation
To achieve the effect you are looking for you can use something like this:
ScrollView delegate method to detect scrolling (if your only paging)
-(void)scrollViewDidScroll:(UIScrollView *)scrollView
{
UIView* subView = [scrollView.subviews lastObject]; //Or however you access your subview
[UIView animateWithDuration:1.0f animations:^{
subView.alpha = 0.0f;
} completion:^(BOOL finished){
[UIView animateWithDuration:1.0f animations:^{
subView.alpha = 1.0f;
}];
}];
}
This will cause your subview to smoothly fade out and in within the span of 2.0 seconds. You should a bit of reading about this animation blocks though as they can be a little tricky. For instance I had nest the second animation block after the first had complete because the actual code within them is handled immediately and the animation simply takes place on the View side of things.
Hope this helps!
You can fade it to zero, change the contentOffset without animation, and fade it back to alpha with 1.0:
- (IBAction)didChangePageView:(id)sender
{
[UIView animateWithDuration:0.25
animations:^{
self.scrollView.alpha = 0.0;
}
completion:^(BOOL finished) {
[self.scrollView setContentOffset:CGPointMake(0, self.scrollView.frame.size.height * self.pageViewControl.currentPage) animated:NO];
[UIView animateWithDuration:0.25 animations:^{
self.scrollView.alpha = 1.0;
}];
}];
}
With Swift 2.0, assuming you hold an array of your subViews in myViewsArray:
func scrollViewDidScroll(scrollView: UIScrollView) {
//Fade in/out effect while scrolling
for (index,subView) in myViewsArray.enumerate() {
label.alpha = 1 - abs(abs(scrollView.contentOffset.x) - subView.frame.width * CGFloat(index)) / subView.frame.width
}
}
What I'm trying to achieve is this :
When a UISlider is scrolled , a small helper view should fades in displaying the current slider value .When the slider is released the helper view fades out . What is the easiest way to do this ?
hi mate just see the code of this example and also use this class for display popupview in iphone..
http://blog.chrismiles.info/2010/12/cmpoptipview-custom-popup-view-for-ios.html
i hope this help you..
:)
Edited:
-(void)addPopUpView{
Yourview.transform = CGAffineTransformMakeScale(1.3, 1.3);
objMakeOfferView.view.alpha = 0;
[UIView animateWithDuration:.35 animations:^{
Yourview.alpha = 0.94;
Yourview.transform = CGAffineTransformMakeScale(1, 1);
}];
objMakeOfferView.view.frame=CGRectMake(0, 0, 120, 80);///set frame which you required
[self.view addSubview:Yourview];
}
-(void)removePopUpView{
[UIView animateWithDuration:.35 animations:^{
Yourview.transform = CGAffineTransformMakeScale(1.3, 1.3);
Yourview.alpha = 0.0;
} completion:^(BOOL finished) {
[Yourview removeFromSuperview];
}];
}
also use different type of TransitionAnimation which you want..

I have a method that gets called if a video upload to Facebook has failed. If that method is called then I would like for a UILabel to briefly appear in any view controller that a user happens to be on at the time the upload fails.
Is this possible?
I asked a similar question earlier about a UIAlertView, but I realized that there are certain circumstances under which an alert could negatively impact user experience.
You can do this is many ways -
1) you can add UILabel to your applications main Window.
2) if you are using a UINavigationController then you get the instance of current viewcontroller and then can add UILabel to its view.
3) if you are using a UITabBarController in this case you can also get the instance of current viewcontroller by accessing tabBarController's selected viewcontroller.
this code Im posting below is from HackBook sample app from facebook. they done similar to what you want.
- (void)showMessage:(NSString *)message {
CGRect labelFrame = messageView.frame;
labelFrame.origin.y = [UIScreen mainScreen].bounds.size.height - self.navigationController.navigationBar.frame.size.height - 20;
messageView.frame = labelFrame;
messageLabel.text = message;
messageView.hidden = NO;
// Use animation to show the message from the bottom then
// hide it.
[UIView animateWithDuration:0.5
delay:1.0
options: UIViewAnimationCurveEaseOut
animations:^{
CGRect labelFrame = messageView.frame;
labelFrame.origin.y -= labelFrame.size.height;
messageView.frame = labelFrame;
}
completion:^(BOOL finished){
if (finished) {
[UIView animateWithDuration:0.5
delay:3.0
options: UIViewAnimationCurveEaseOut
animations:^{
CGRect labelFrame = messageView.frame;
labelFrame.origin.y += messageView.frame.size.height;
// UIView *messageView; declared in header
messageView.frame = labelFrame;
}
completion:^(BOOL finished){
if (finished) {
messageView.hidden = YES;
messageLabel.text = #"";
}
}];
}
}];
}
The main UIView contains two subviews - UIView_1 and UIView_2.
In the UIView_2, there is a button to show or hide the UIView_1.
For example, when a user touches the button to show the UIView_1, then UIView_1 will slide down and UIView_2 will push downwards with transition.
I have very little knowledge in animation. Can someone show me some sample code for reference?
Should I use CGAffineTransformMakeTranslation?
Thanks.
You don't need anything so complex. Just change the view's frame size.
NSTimeInterval animationDuration = /* determine length of animation */;
CGRect newFrameSize = /* determine what the frame size should be */;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:animationDuration];
theViewToChange.frame = newFrameSize;
[UIView commitAnimations];
Simply Hide/show with fadein/out effect
`
/To Show/
sliderView.hidden = NO;
sliderView.alpha = 0.1;
[UIView animateWithDuration:0.25 animations:^{
sliderView.alpha = 1.0f;
} completion:^(BOOL finished) {
// do some
}];
/To hide/
[UIView animateWithDuration:0.25 animations:^{
sliderView.frame = CGRectMake(130, 30, 0, 0);
[sliderView setAlpha:0.1f];
} completion:^(BOOL finished) {
sliderView.hidden = YES;
}];
`
It depends on what you want to do with UIView_2.
Place UIView_1 below UIView_2 in Interface Builder.
Size UIView_2 to take up all the space below the UINavigationBar.
Use the following code to either resize (using uiview2_resized_rect) the frame for UIView_2, or translate/move the frame for UIView_2 (using uiview2_translated_rect ):
CGRect uiview1_original_rect = UIView_1.frame;
CGRect uiview2_original_rect = UIView_2.frame;
CGRect uiview2_translated_rect = CGRectMake(uiview2_original_rect.origin.x,
uiview2_original_rect.origin.y+uiview1_original_rect.size.height,
uiview2_original_rect.size.width,
uiview2_original_rect.size.height);
CGRect uiview2_resized_rect = CGRectMake(uiview2_original_rect.origin.x,
uiview2_original_rect.origin.y+uiview1_original_rect.size.height,
uiview2_original_rect.size.width,
uiview2_original_rect.size.height-uiview1_original_rect.size.height);
[UIView animateWithDuration:0.300 delay:0.0
options:UIViewAnimationOptionCurveEaseInOut|UIViewAnimationOptionBeginFromCurrentState
animations:^{
//uncomment this and comment out the other if you want to move UIView_2 down to show UIView_1
//UIView_2.frame = uiview2_translated_rect;
UIView_2.frame = uiview2_resized_rect;
} completion:^(BOOL finished) {
}];
Sorry for the poor title, I am trying to think of a easy way to explain this.
I have a UIView in the center of the screen which contains a progress indicator and background image.
What I want it to do is get bigger to a certain point and then shrink a tiny bit. So it "boings" in.
I had a play with normal UIView animations etc and have it coming in. However I thinking to get this to work well I need to use the views layer. The main issue at the moment is the indicator does not size.
Has anyone done a boing effect on a view?
Something like this?
- (void)boingView:(UIView *)theView {
[UIView animateWithDuration:0.1 animations:^(void) {
theView.transform = CGAffineTransformMakeScale(1.3, 1.3);
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.1 animations:^(void) {
theView.transform = CGAffineTransformMakeScale(0.8, 0.8);
} completion:^(BOOL finished) {
[UIView animateWithDuration:0.1 animations:^(void) {
theView.transform = CGAffineTransformMakeScale(1.0, 1.0);
} completion:nil];
}];
}];
}
