My program has a UIToolBar which contains a UITextField and a UIButton. The whole view (self.view) goes when the soft keypad comes up. As the UIToolBar is moved to a new position, the button sometimes doesn't capture events properly. Several clicks on the button is required to fire a single event.
The following set of code is executed when the keyboard comes up
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.25];
self.view.frame = CGRectMake(0,-220,320,400);
tableView.frame = CGRectMake(10, 220, 320, 264);
[UIView commitAnimations];
Try this
[UIView animateWithDuration:0.25 delay:0.0 options:UIViewAnimationOptionAllowUserInteraction animations:^{
self.view.frame = CGRectMake(0,-220,320,400);
tableView.frame = CGRectMake(10, 220, 320, 264);
}completion:^(BOOL finished) {}];

I have UIView, in top of it i have an UIImageView, in bottom UICollectionView. My point is, when user swipe finger up, UIImageView frame should gently move out (disappear), and when user swipe down, it should again appear (with moving animation).
Actually, it worked until i set image to UIImageView. Old code (presented below) did it work just fine:
-(void)handleSwipeDown:(UISwipeGestureRecognizer *)recognizer {
NSLog(#"Swipe received.");
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
self.myCollectionView.frame = CGRectMake(0, 152, 320, 480);
[UIView commitAnimations];
}
And then:
-(void)handleSwipeFrom:(UISwipeGestureRecognizer *)recognizer {
NSLog(#"Swipe received.");
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
self.myCollectionView.frame=CGRectMake(0, 0, 320, 480);
[UIView commitAnimations];
}
After i set image:
UIImage *firstImage = [UIImage imageNamed:#"ipd1.jpg"];
self.imageSlideshow.image = firstImage;
Code above stop work. UIImage frame stay in same place.
How could i make it move ?
Any advice would be appreciated, thanks!
You should stop using the beginAnimations:context: and commitAnimations block. From Apple's documentation:
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.
Use this instead:
[UIView animateWithDuration:0.5 animations:^{
self.myCollectionView.frame = CGRectMake(0, 152, 320, 480);
}];
Just replace your entire swipeDown method with the above.
I have a view currently on the screen and I would like to move it off the screen during an animation. Its current position is: CGRectMake(0, 168, 320, 50); and I would like to move it to y postion 218.
Here is my code:
[UIView beginAnimations:Nil context:NULL];
[UIView setAnimationDuration:0.3];
self.optionsView.frame = CGRectMake(0, 218, 320, 50);
[UIView commitAnimations];
Thanks in advance. Nothing is happening, the view isnt moving off screen.
Edit: When the app launches the view is off screen, i then call:
[UIView beginAnimations:Nil context:NULL];
[UIView setAnimationDuration:0.3];
self.optionsView.frame = CGRectMake(0, 168, 320, 50);
[UIView commitAnimations];
to bring the view into the main view. The problem I have is making the view go back off screen again with:
[UIView beginAnimations:Nil context:NULL];
[UIView setAnimationDuration:0.3];
self.optionsView.frame = CGRectMake(0, 218, 320, 50);
[UIView commitAnimations];
It must be noted that in order to get the view to be off screen on app launch I call:
-(void) viewDidLayoutSubviews{
self.optionsView.frame = CGRectMake(0, 218, 320, 50);
}
Update: I am also using the camera, i think dismissing the camera is affecting the layouts
I've animated the position of views as follows:
// 'frame' variable previously declared
// 'completion' block previously declared
[UIView animateWithDuration:0.3f
delay:0.0f
options:UIViewAnimationOptionCurveEaseInOut
animations:^{
[_someView setFrame:frame];
}
completion:^(BOOL finished){
if (completion) {
completion();
}
}];
Have you tried it that way?
As Martin Koles has said, the block-based approach to view animation is preferred. The following is in the reference doc for UIView:
Use of the methods in this section is discouraged in iOS 4 and later.
Use the block-based animation methods instead.
https://developer.apple.com/library/ios/documentation/uikit/reference/uiview_class/UIView/UIView.html
Use block instead:
[UIView transitionWithView:self.view duration:0.3 options:UIViewAnimationOptionCurveEaseInOut animations:^{
// final view elements attributes goes here
} completion:nil];
This is the modern way of doing animations. You can even specify a completion block, something that should happed after the animation is done, if needed.
Try using this
[UIView animateWithDuration:0.3 delay:0 options: UIViewAnimationOptionCurveLinear
animations:^{
self.optionsView.frame = CGRectMake(0, 218, 320, 50);
} completion:nil];
Worked fine with me.
Make sure the view is connected in the xib to its proper object.
I have developed a font selection that utilizes UIPickerView and UIToolbar, which are both added on touching a UIButton.
But they just kind of pop in which looks sloppy.
is there a way to animate them?
here is the method that adds them (it's called on clicking the button) :
-(void)showPicker
{
[self.view addSubview:_fontPicker];
[self.view addSubview:pickerTB];
}
You can animate them in a couple of ways, but probably the easiest is to just fade them in.
Fade In
[someView setAlpha:0]
[self.view addSubview:someView];
[UIView beginAnimations:#"FadeIn" context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationBeginsFromCurrentState:YES];
[someView setAlpha:1];
[UIView commitAnimations];
Fade Out
float fadeDuration = 0.5;
[UIView beginAnimations:#"FadeOut" context:nil];
[UIView setAnimationDuration:fadeDuration ];
[UIView setAnimationBeginsFromCurrentState:YES];
[someView setAlpha:0];
[UIView setAnimationDidStopSelector:#selector(removeView)];
[UIView commitAnimations];
-(void) removeView {
[someView removeFromSuperview];
}
Something as simple as that.
Depends on what type of animation you want to use. For example, this would look like dissolve.
Anyways look into UIView animateWithDuration...
pickerTB.alpha = _fontPicker.alpha = 0;
[self.view addSubview:_fontPicker];
[self.view addSubview:pickerTB];
[UIView animateWithDuration:1 animations:^{_fontPicker.alpha = 1; pickerTB.alpha = 1}];
You could use transforms or change frame origins to make the views fly in from positions outside the screen too. In that case, inside the animations block, specify the new on screen position. You can do this in two ways, change the frame with an updated origin or apply a CGAffineTransformMakeTranslation(dx,dy)
You need to add the subview with a frame value that is where you want the animation to begin from (off-screen?) then change the frame value inside your animation block. The frame will change over the duration, causing the appearance of movement. The view must already be a subview - I don't believe adding a subview is something you can animate, it makes no sense.
-(void) showPicker{
[self.view addSubview: _fontPicker];
_fontPicker.frame = CGRectMake(0, 0, 120, 40);// somewhere offscreen, in the direction you want it to appear from
[UIView animateWithDuration:10.0
animations:^{
geopointView.frame = // its final location
}];
}
Initially set your picker view frame and tool bar frame like this one..
-(void)viewDidLoad
{
[super viewDidLoad];
pickerTB.frame = CGRectMake(0,568,320,44);
fontPicker.frame = CGRectMake(0, 568, 320, 216);
}
-(void)showPicker
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:.30];
if(isiPhone5)
{
pickerTB.frame = CGRectMake(0,288,320,44);
fontPicker.frame = CGRectMake(0, 332, 320, 216);
}else{
pickerTB.frame = CGRectMake(0,200,320,44);
fontPicker.frame = CGRectMake(0,244, 320, 216);
}
[UIView commitAnimations];
}
Im trying to animate a UIView with this code:
[self.view bringSubviewToFront:RegNrView];
[UIView animateWithDuration:.5 animations:^{
RegNrView.frame = CGRectMake(0, 0, 320, 460);
}
completion:^(BOOL finished) {
}];
The RegNrView is a UIView containing a UITextField and has the frame: (320,0,320,460).
This is called from an IBAction. The first call nothing happens, but the second time it works. Why does it do that?
I have a screen with several buttons from top to bottom and when they touched, they will show pickerview and uidatepicker. the problem is how to scroll the view if uidatepicker blocked the button.
so i want scroll view working here just like when uikeyboard appear. thanks! :)
ps: i really want to upload the images but my reput don't allow me to do that :)
update:
in the end i use this on my code and the animation looks similar with tpavoiding scroll, here is the code
[UIView animateWithDuration: 0.5f animations:^{
self.containerView.frame=CGRectMake(0, -120, 320, 308);
}
completion:^(BOOL finished) {} ];
so containerView will move up 120, and when i click done(toolbar above the uidatepicker) i just make it to normal position.
[UIView animateWithDuration: 0.5f animations:^{
self.containerView.frame=CGRectMake(0, 0, 320, 308);
}
completion:^(BOOL finished) {} ];
Use UIView animations:
[UIView animateWithDuration: duration animations:^{ myView.frame = CGRectMake(0, 0, 320, 320);} completion:^(BOOL finished) { [self doSomething]; } ];
