how i can move a subview in a UIView to out of UIView frame, and see that value of outside in bottom! sorry please see my picture for understand, i dont want to use scrollview, and dont use duplicate views to do this.
thanks
You have to duplicate the subview. There's no other way, because you can't add the same subview twice.
If you try to add an existing subview to another view, it will be automatically removed from it's superview.
After the view is duplicated, you can animate both of them in the way you described.
UPDATE
Here create same two subview , after that set frame both like bellow...
- (void)viewDidLoad
{
yourSubview1.frame = CGRectMake(yourSubview1.frame.origin.x, 200, yourSubview1.frame.size.width, yourSubview1.frame.size.height);
yourSubview2.frame = CGRectMake(yourSubview2.frame.origin.x, 400, yourSubview2.frame.size.width, yourSubview2.frame.size.height);
}
and after when you want to move subview at that time just call bellow code ...
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.3];
yourSubview1.frame = CGRectMake(yourSubview1.frame.origin.x, yourSubview1.frame.origin.y - 100, yourSubview1.frame.size.width, yourSubview1.frame.size.height);
yourSubview2.frame = CGRectMake(yourSubview2.frame.origin.x, yourSubview2.frame.origin.y - 100, yourSubview2.frame.size.width, yourSubview2.frame.size.height);
//// set `y` where you want to display just like i minus the y with 100 so its move above with 100 point of y
[UIView commitAnimations];
This is just an example you can set this with your frame and timer ..
i hope this help you....

I am trying to make a simple application where there are 3 buttons. When user clicks any of the button, they are animated(moved) to their new positions! All this works from this code:
[UIView animateWithDuration:1.2
delay:0.1
options: UIViewAnimationCurveEaseOut
animations:^
{
//Moving the Sum (UIButton which will move through this animation)
CGRect frame = Sum.frame;
frame.origin.y = -20;
frame.origin.x = (-120);
Sum.frame = frame;
.....
....
}
completion:^(BOOL finished)
{
NSLog(#"Completed");
//adding subview after the animation is complete! newView is an example!
[self.view addSubview:newView];}];
The Problem is that once i add a subview to the main view, All buttons come back to their old position! meaning they weren't moved permanently.. how can i solve this? Plz help guys!
What happens when you add a view? A layout is performed. You could have done two mistakes
You are using autolayout.
If you are using autolayout, changing frames directly is not advised and a relayout will update the views to their original position using current constraints.
You are setting the frame position in layoutSubviews, viewWillLayout or viewDidLayout.
Check where you are setting the original position. Can the method be called multiple times?
You have save the X,Y Position of the new frame & then set this frame by coding.
I have a headerView which can expand and collapse when pressed. It's default state is collapsed.
I use the following code to expand the headerView.
if (!self.headerViewIsExpanded) {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[self.collapsedHeaderView removeFromSuperview];
self.headerView.frame = self.expandedHeaderView.frame;
[self.headerView addSubview:self.expandedHeaderView];
self.tableView.frame = CGRectMake(self.tableView.frame.origin.x, self.tableView.frame.origin.y + offset, self.tableView.frame.size.width, self.tableView.frame.size.height - offset);
[UIView commitAnimations];
self.headerViewIsExpanded = YES;
}
It correctly expands the view frame and diminishes the tableView frame. However, it fails to expand the touches received area of the original UIControl, so I can only collapse it by pressing where the original frame was.
How can I resolve this issue?
EDIT: Alternatively, I would accept an answer with a good explanation of why I cannot resolve the issue, or at least not resolve it safely.
EDIT 1: To be more clear, the headerView is NOT a tableView header view. It is just a view that sits on top of the table that happens to be called headerView. Both headerView and tableView are subviews of the main UIView that spans the available window.
You can try to overload layoutSubviews method. Inside you should use setFrame method for your headerView to define all view elements position.
I am animating UIView when user touches on custom dropdown to show picker View from bottom side.UIView contains Pickerview...so when I change it's frame to move upwards.I get what I want, but pickerView doesn't recognize touch !(see screenshot below)
code is like this
CGRect pickerFrame=self.pickerSheet.frame;
CGRect viewFrame=self.view.frame;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:SHEET_ANIMATION_DURATION];
//change Frame of View containing UIPickerView
pickerFrame.origin.y=202+animatedDistance;
viewFrame.origin.y-=animatedDistance;//animated distance is value by which view needs to move upward.
[self.pickerSheet setFrame:pickerFrame];
[self.view setFrame:viewFrame];
[UIView commitAnimations];
screenshot
first of all, ++please**, stop using this animation declaration, and bedin use new, block animation:
[UIView animateWithDuration:SHEET_ANIMATION_DURATION
delay:0
options:nil
animations:^{
pickerFrame.origin.y=202+animatedDistance;
viewFrame.origin.y-=animatedDistance;
}
completion:^(BOO f){
//any actions after animation ended
}];
Second, I think your problem is somewhere else. May by, you implementing your touches or picker wrong.
Please start using the new , better animation block , but I think there is something missing in your code , you need to put the code below :
UIViewAnimationOptionAllowUserInteraction
Put this code in options in the new animation block , or find a way to put it in the old animation block
I have a single UIView with some labels that display attributes from objects inside an array. I'm using gesture recognizers to change the current element in the array and hence the text in the labels. My question is how do I mimic a push animation without actually pushing a new view controller. Thanks for your help.
Thats simple way to use CGAffineTransformMakeTranslation to move any view from X axis to Y axis using UIViewAnimation. Before using this transition set your object frame to some x,y axis(0,0) and pass your x and y to move from.
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.4];
CGAffineTransform transform = CGAffineTransformMakeTranslation(x,y);
YOUR ViewOBJECT.transform=transform;
[UIView commitAnimations];
Have you tried to use the UIView class methods for animation? For example this could help:
+ (void)animateWithDuration:(NSTimeInterval)duration animations:(void (^)(void))animations
In the animations block you could move one view out and another in.
I have added a button on a view(the view is of the same size as the button). When that button is clicked a new view has to be displayed. So in the button's event handler I have added the newview as a subview of the view on which the button is added, so that the newview gets displayed when the button is clicked. The thing here I need to do is, when I click on the button, the newview has to be invoked from top to bottom (it has to look like it slides down from the button's view). When the same button is clicked again, the newview has to scrollback(slide) and disappear. I know that I need to apply some animation stuff to get this effect. But I have no idea how to do this. Can you please help me giving some ideas.
Thanks in advance!!!
Well you can animate the size of your window to simulate the slide from top like this:
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
myView.frame = CGRectMake(0, buttonHeight+buttonTop, myView.frame.size.width, viewTargetHeight);
[UIView commitAnimations];
Make sure you set the view height to 0 when you create it.
To scroll it back up just do the opposite
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
myView.frame = CGRectMake(0, buttonHeight+buttonTop, myView.frame.size.width, 0);
[UIView commitAnimations];
If you actually want your new view to slide you can try animating both the size and the position and you'll also probably need to clip your animated view with another view.
