How can I move my UIView in xcode?

Question

I have a view controller with a collection view on it. I dragged a UIView onto the view controller as you can see below.

I attached a label, also note the white border is from the collection cell.

Then, In the CollectionViewController class that is attached to the actual view controller, (the UIView doesn't have a custom class) I created an outlet and attached it to the UIView .

@property (strong, nonatomic) IBOutlet UIView *infoView;

Then I synthesised it: @synthesize infoView;

Now, in the ViewDidLoad method, I want to be able to move the view down out of the screen so its not visible.

I have tried using CGRect and CGPointMake but it just doesn't move! Can someone show me the exact code I can use to move the UIView by my desired amount within the ViewDidLoad method?

Answer 1

First remove the view from superview

[infoview removeFromSuperView];

After that you can adjust the new frame of view

infoview.frame = CGRectMake(x,y,width,height);

Now add the view again to superview

[self.view addSubVeiw:infoView];

To animate a view to a new frame, use the following code

infoView.frame =  CGRectMake(x,y,width,height);//initial frame
    [UIView animateWithDuration:0.25 animations:^{
       infoView.frame =  CGRectMake(x,y,width,height);//new frame
    }];

Subviews are not properly set yet in viewDidLoad . Try moving your subview in

- (void)viewDidLayoutSubviews {
    [super viewDidLayoutSubviews];

}
