I am running AdMob on my app, but the tutorial provided by google has the banner on top of the app, i want it at the bottom of the app/screen, i use rows 0 to 17, so anything after row 18 is fine.
This is the method that draws the ad if one was received:
-(void) adViewDidReceiveAd:(GADBannerView *)adView
{
[UIView animateWithDuration:1.0 animations:^{adView.frame = CGRectMake(0.0, 0.0, adView.frame.size.width, adView.frame.size.height);
}];
}
What would i need to do to have it displayed at the bottom of the screen?
Thank you guys.
Set the Y position to the height of the screen minus the height of the view (in landscape orientation you need to use the width of the screen instead):
adView.frame = CGRectMake(0.0, [UIScreen mainScreen].bounds.size.height.y - adView.frame.size.height, adView.frame.size.width, adView.frame.size.height);
I assume you are in the view controller:
[UIView animateWithDuration:1.0 animations:^{adView.frame =
CGRectMake(0.0,
self.view.bounds.size.height-adView.frame.size.height,
adView.frame.size.width,
adView.frame.size.height);
}];

I created a floating view for my application which always displays on screen.
Now I want to make a half of it go outside my screen when it is interactive for 3-4 seconds. I think I should use a NSTimer to hide out this view, but it is not the problem.
The problem is how should I set origin.x of this view to go outside of the screen? I've tried to set the frame in my initWithSuperView like this:
CGRect screenRect = [[UIScreen mainScreen] bounds];
CGFloat screenX = screenRect.origin.x;
[self setFrame:CGRectMake(-screenX - size.width, 0, size.width, size.height)];
However, it doesn't work. How should I do it to get my desired result? See image below for more information:
you can use uiview animation similar to this:
dispatch_async(mainQueue, ^{
__weak __typeof(self) weakSelf = self;
[UIView animateWithDuration:3.f animations:^{
// change uiview frame here
weakSelf.frame = hiddenFrame;
} completion:^(BOOL finished) {
// setup completion
[weakSelf.view layoutIfNeeded];
}];
});
also you can setup NSLayoutConstraint to the x constraint of uiview and update it with negative value when you need.
I have two views side by side(left & right).At one time i am just showing one view other view not visible because i have moved that view out of scene towards the right of screen.I have set the x position in such a way so that it is not visible(view is always to the right of screen so not visible).So i press next button which is near to first view then my second view is visible & first view is hidden. I have used animation to slide thew view from left to right & right to left.

On the backView i have added a subview on bottom-right so when ever i try to add the view inside that view then then main view is shifted to the right i don't know why.Please tell me how can i get the solution?
I have embedded all my views in a UIScrollView from xib. The scrollview contents cover all screen below status bar. Now when the textfield is tapped, I am able to move the scrollview little up. But I want it to be completely scrollable till the bottom most view is also visible above the keyboard. Also when the scrollview is scrolled till top , it should come to normal original positions. Hence, Overall I want a completely scrollable functionality like mentioned above for my scrollview.
I am done with following tricks but with no luck:
Trick 1: Change the height of the scrollview so that the content is more than scrollview height and hence the view is scrollable:
-(void)keyboardWillAppear:(NSNotification *)sender
{
CGFloat y_offset=0;
if([UIScreen mainScreen].bounds.size.height == 480){
y_offset = 80;
} else {
y_offset = 70;
}
NSDictionary* userInfo = [sender userInfo];
CGRect keyboardEndFrame;
[[userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] getValue:&keyboardEndFrame];
keyboardHeight = keyboardEndFrame.size.height;
[UIView animateWithDuration:0.5f animations:^{
[self.view setFrame:CGRectMake(0, - y_offset, self.view.frame.size.width, self.view.frame.size.height)];
}];
[self.loginScrollView setFrame:CGRectMake(self.loginScrollView.frame.origin.x, self.loginScrollView.frame.origin.y, self.loginScrollView.frame.size.width, [UIScreen mainScreen].bounds.size.height - keyboardHeight)];
}
-(void)keyboardWillDisappear:(NSNotification *)sender
{
[UIView animateWithDuration:0.5f animations:^{
[self.view setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
}];
[self.loginScrollView setFrame:CGRectMake(self.loginScrollView.frame.origin.x, self.loginScrollView.frame.origin.y, self.loginScrollView.frame.size.width, [UIScreen mainScreen].bounds.size.height)];
}
Trick 2: As per other suggestions, I changed the contentInset of the UIScrollView.
In keyboardWillAppear method I added following code:
CGSize kbSize = [[userInfo objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbSize.height+100, 0.0);
self.loginScrollView.contentInset = contentInsets;
self.loginScrollView.scrollIndicatorInsets = contentInsets;
and in keyboardWillDisappear method I set the contentInset back to zero values.
Hence, let me know if there needs to be any other way to sort this out or any other possible changes I need to make in scrollview frame. Moreover , if I turn on the bouncesVertically functionality it is able to bounce even when complete subviews are visible onscreen which I don't want. So basically I want it to freeze when keyboard is not there and scrollable till viewable area when it is up. Hence, give me any other suggestions? Thanks in advance.
From a conceptual point of view when "scrollView Size == scrollView ContentSize", it does not scroll. To make it scrollable we need to increase the contentSize. In your problem you need to adjust the contentSize of scrollView along with frame. This can be done in your first approach.
As for the second approach, changing the edge insets will create a sort of padding for the content drawable area. This can make the bottom content visible, but it won't affect the contentSize, hence view will not be scrollable.
-(void)textFieldDidBeginEditing:(UITextField *)textField
{
[self animateTextField:textField up:YES];
}
-(void)textFieldDidEndEditing:(UITextField *)textField
{
[self animateTextField:textField up:NO];
}
-(void)animateTextField:(UITextField*)textField up:(BOOL)up
{
const int movementDistance = -60; // change this size if you need
const float movementDuration = 0.3f; // change this size if you need
int movement = (up ? movementDistance : -movementDistance);
[UIView beginAnimations: #"animateTextField" context: nil];
[UIView setAnimationBeginsFromCurrentState: YES];
[UIView setAnimationDuration: movementDuration];
self.view.frame = CGRectOffset(self.view.frame, 0, movement);
[UIView commitAnimations];
}
it is useful for me
I can really recommend this library:

It's very very easy to use, and works for ScrollView, TableView and CollectionView!
When I rotate the iPad, all the animated components (e.g. views/buttons) will go back to their original position as to when it was first loaded. Is there any way to prevent this?
Here is how I animate object when I click an button e.g.
- (IBAction)button1Pressed:(id)sender{
[UIView animateWithDuration:ANIMATION_SPEED
delay:0.0
options:UIViewAnimationOptionBeginFromCurrentState
animations:(void (^)(void)) ^{
self.view.userInteractionEnabled = NO;
_button1.center = CGPointMake(73.01, 419.0);
_button2.center = CGPointMake(750.0, 419.0);
_button3.center = CGPointMake(850.0, 419.0);
_button4.center = CGPointMake(950.0, 419.0);
CGRect theFrame = _loginView.frame;
theFrame.size.width = 576.f;
_View1.frame = theFrame;
_View2.frame = CGRectMake(_button2.center.x + 44.0, _button2.center.y / 2 - 89.0, 0.0, 597.0);
_View3.frame = CGRectMake(_button3.center.x + 44.0, _button3.center.y / 2 - 89.0, 0.0, 597.0);
_4View.frame = CGRectMake(_button4.center.x + 44.0, _button4.center.y / 2 - 89.0, 0.0, 597.0);
}
completion:^(BOOL finished){
self.view.userInteractionEnabled = YES;
}];
}
I'm still quite new so all the details will be appreciated :)
I suggest you to create constraints for the interface you want to animate. Then add reference to your header file for those constraints as for any view element.
When you want to animate a view, you now have to update its constraints and ask to layout the views.
[UIView animateWithDuration:0.2
animations:^{
//in this case, I add 44 to my button Y position, so it will goes down 44px
buttonYConstraint.constant += 44;
[self.view layoutIfNeeded];
}
]
//Now don't forget to update constraints
[self.view updateConstraints];
Turning off auto layout located under the 'Interface builder document' fixed this in quick fashion :)
I have a UIView at the bottom left of its superview, i.e.its frame is like
[myView setFrame:CGRectMake(0,superView.bounds.size.height-myViewHeight,myViewWidth,myViewHeight)];
I want to animate its size such that its bottom left point remains fixed at its position. I am not sure how to play with anchor point property of layers.
Currently I am increasing its size using the following lines of code.
[UIView animateWithDuration:0.2 animations:^{
[bottomLbl setFrame:CGRectMake(0, bottomView.bounds.size.height-250, 300, 250)];
This works fine but when I try to bring back to its original size, its bottom point gets lifted at the start of animation and settles down at the end of animation.
First define the point for the bottom left corner...
CGPoint bottomLeft = CGPointMake(0, 480); // this can be anything.
Then you need to define the sizes (big and small).
CGSize bigSize = CGSizeMake(280, 280);
CGSize smallSize = CGSizeMake(50, 50); // again, these can be anything.
Then animate them...
// create the rect for the frame
CGRect bigFrame = CGRectMake(bottomLeft.x, bottomLeft.y - bigSize.height, bigSize.width, bigSize.height);
CGRect smallFrame = CGRectMake(bottomLeft.x, bottomLeft.y - smallSize.height, smallSize.width, smallSize.height);
[UIView animateWithDuration:0.2
animations:^{
// set the rect onto the view
bottomLbl.frame = bigFrame;
// or
bottomLbl.frame = smallFrame;
}];
As long as you set the frame and the calculated end frames are correct and it's all done in one animation then the bottom left corner won't move.
If this doesn't help can you please post a video of what is happening (and all your animation code).
EDIT
[UIView animateWithDuration:0.2
delay:0.0
options:UIViewAnimationOptionBeginFromCurrentState
animations:^{
// set the rect onto the view
bottomLbl.frame = bigFrame;
// or
bottomLbl.frame = smallFrame;
}
completion:nil];
