I just wanted to create animation for clock to appear as in this video.
I have no idea how create it. Any solution?
When you click on bulb icon in slider below, the clock will appear and on clicking again clock will disappear.
If you want your app to be iOS < 4 compatible, use this:
[UIView beginAnimations:#"animation" context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveLinear]; //Different Animation Curves available, check docs.
[UIView setAnimationDuration:1.0]; //In seconds
//Here do your stuff
int newPosY = myImage.frame.origin.y - 10;
[myImage setFrame:CGRectMake(self.frame.origin.x, newPosY, myImage.frame.size.width, myImage.frame.size.height)];
[UIView commitAnimations];
This snippet moves your image 10 pixels up. You can customize the animation making changes to the image frame before calling commitAnimations
Also check the UIView Reference to extended info.

i am developing a app and it has this button call menu. When i click that button it addsubview the menu view to the main view. But I need to add it like comming out from the button. Like speech bubble.
Here is a sample image i take from some iphone app and they did awesome job to animate the view, like a bubble come out from button.
this is the app i am talking about which is having the animation i mentioning.
Download Waze App from here
if you are using iphone, download it and take a look at it. Then you will get proper idea about how that animation happening. Its a free app btw.
I search through the net to find a solution for this but i couldn't find any thing helpful. There are some ideas to do it like scalling the subview, using following code. I tried it with some view animations, it has some progress but not good enough.
CGAffineTransform transform = CGAffineTransformMakeScale(1.2, 1.2);
But I am pretty sure that is not the correct way to do it. There should be a proper way to do it.
Can any one give me help me to over come this issue.
Thanks in Advance
In my project I have used the following code for animating from left to right. Changing the value for CGAffineTransform (x and y position) will provide variations. Hope this would help you!
[self.view addSubview:subView];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.0];
CGAffineTransform t2 = CGAffineTransformMakeTranslation(SubView_Width, 0);
subView.transform = t2;
subView.alpha = 1;
[UIView commitAnimations];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1];
[UIView setAnimationDelegate:self];
subView.alpha = 1;
subView.transform = CGAffineTransformIdentity;
[UIView commitAnimations];

I am developing a Cocos2D game. On a stage a show a UIView giving users a list of tasks to perform. There are text fields which I move up or down using Animation. My code is below.
[textField setFrame:CGRectMake(textField.frame.origin.x, textField.frame.origin.y, textField.frame.size.width, textField.frame.size.height)];
[inviteButton setFrame:CGRectMake(inviteButton.frame.origin.x, inviteButton.frame.origin.y, inviteButton.frame.size.width, inviteButton.frame.size.height)];
[headingLabel setFrame:CGRectMake(headingLabel.frame.origin.x, headingLabel.frame.origin.y, headingLabel.frame.size.width, headingLabel.frame.size.height)];
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
[UIView setAnimationDelegate:self];
[textField setFrame:CGRectMake(textField.frame.origin.x, textField.frame.origin.y-50, textField.frame.size.width, textField.frame.size.height)];
[inviteButton setFrame:CGRectMake(inviteButton.frame.origin.x, inviteButton.frame.origin.y-50, inviteButton.frame.size.width, inviteButton.frame.size.height)];
[headingLabel setFrame:CGRectMake(headingLabel.frame.origin.x, headingLabel.frame.origin.y-30, headingLabel.frame.size.width, headingLabel.frame.size.height)];
[UIView commitAnimations];
[self.view.layer removeAllAnimations];
Problem is that even after user is done and he presses the cancel button to remove this view from the super view, every view including UIAlertView and other subviews appearing in my map after removing that view are effected by the animation i used to move text fields and label up or down. UIAlertView is using same Animation to show up and so is happening other subviews. Can anyone please tell me why this is happening?
Best Regards
You have to set the animationID to a unique value in the beginAnimations:context: method.
See the official doc
Also this doc states:
Use of this method is discouraged in iOS 4.0 and later. You should use the block-based animation methods to specify your animations instead.
I am very new to animation in iphone . To start with i wanted to implement spinning of earth or globe . how can i do implement it in iphone
thanks in advance
For 2D animation you would need a number of frames (ideally 360) and then step through the frames in an UIImageView. You can set the animationImages property using this example
you can use this...this is not spinning but moving image from one location to another
CGRect tempFrame=theView.frame;
tempFrame.origin.x=tempFrame.origin.x+50;
[UIView beginAnimations:#"" context:nil];
[UIView setAnimationDuration:2];
theView.frame=tempFrame;
[UIView commitAnimations];
I have a custom view that has to track the user's location. I put the following code in touchesBegan, as well as in touchesMoved:
[UIView animateWithDuration:0.2 delay:0.0 options:UIViewAnimationOptionBeginFromCurrentState animations:^{
cursorView.center = locationOfTouch;
} completion:^(BOOL finished){}];
It seems fairly straightforward to me. I'd expect the view to always animate to the user's current location, even if that location is changed and the view is still animating (because of the beginFromCurrentState option).
Yet, each animation finishes completely. They don't 'transition' to the new animation, no they finish first, then they start the new animation.
I tried adding this line in touchesMoved:
[cursorView.layer removeAllAnimations];
Doesn't do anything. No animation is cancelled. Any ideas?
with [cursorView.layer removeAllAnimations]; you access the layer of the view but you have set the animation not to the layer but the view directly.
Try:
[UIView beginAnimations:nil context:NULL]
[UIView setAnimationDuration:0.2];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
cursorView.center = locationOfTouch;
[UIView commitAnimations];
and leave out the removeAllAnimations and it should transition from current state.
Looks like this is a derivative of another question you asked that I just answered, but the same idea applies.
You don't need to use blocks to do this. Just wrap your setCenter in a UIView animation. Like this:
[UIView beginAnimations:nil context:NULL]
[UIView setAnimationDuration:0.2f];
cursorView.center = locationOfTouch;
[UIView commitAnimations];
Keep in mind that 0.2 seconds is pretty fast. It may appear to be "jumping" to the position. To confirm, set the duration to something like 2.0 seconds and see if it's animating.
Best regards.
Technically, the view should automatically animate with a default time of 0.25 seconds. That is what the manuals say, however, I'm currently on here because the manuals don't seem to be very accurate regarding animation.
Also, the beginAnimations call is being phased out, you might want to use a CATransaction instead
I have a UIImageView that is displaying a series of pictures as an animation. This part of the project works well.
I want to display a label when the animation ends. Is there an event that the Imageview will trigger when it's animation ends?
Set the duration the animation will go using setAnimationDuration:
At the same time you configure performSelector:withObject:withDelay with the same delay as the duration the animation will go on
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0]; //the animation will last for 1.0s
//some animation code here
[UIView commitAnimations];
[self performSelector:#selector(someMethodToDisplayLabel) withObject:nil afterDelay:1.0];
//someMethodToDisplayLabel will be called after 1.0s
Doesn't look like there is an event/delegate for this. My first instinct would be to calculate the length of the animation yourself, and then set up an NSTimer so that when the animation ends, NSTimer fires displaying whatever you want to display next.
