wish help you to fix your issue This issue is related to the constraints that need to be set to the scroll view. I have answered a similar question here. Basically you need to specify a constraint for the scroll view's content view's width. See my answer in above link for a detailed description. The problem is that the scrollview adjusts its size to its content view's size even after we provide proper constraints to the scroll view. So we need to specify the constraints of the content view of the scroll view with respect to the scrollview and its superview so that the content in the scrollview fits our requirement.

this one helps. I am adding subviews to my scrollview according to the number of array elements in a for loop.The container view has an additional subview inside.The problem is that only the first container views contains the added subview and the new one does not but the third one also has it.I checked the Frame of the subviews but still does not seem to work.

code :

backgroundImage.center = CCGPointMake(lvPackageContainerFrame.size.width/2, lvPackageContainerFrame.size.height/2);

center.x = (frame.origin.x + frame.size.width) / 2;
center.y = (frame.origin.y + frame.size.height) / 2;

center.x = (320 + 320) / 2;
center.y = (0 + 480) / 2;

I hope this helps . you have added all the view to your scroll so,enumerate UIView from scrollview and add your anotherSubview to your UIView

   [myView addSubview:anotherSubview];

To fix the issue you can do I have an iOS project that adds a subview to a nib. The subview's contents are set to the center using autolayout, but when the subview is added to the scrollview, the subview's contents are not on center. Here is the code: , I solved it. Here's the code I used:

code :

UIView *scroller = [[[NSBundle mainBundle] loadNibNamed:@"scroller" owner:self options:nil] objectAtIndex:0];
[self.view addSubview:scroller];

CGSize size = self.view.bounds.size;
self.scrollView.contentSize = CGSizeMake(size.width, size.height+200);
self.myView.frame = CGRectMake(0, 0, size.width, size.height);
[self.scrollView addSubview:self.myView];

Hope this helps You need to change the Y to be incrementing as according to your code all images have the same frame

code :

let newImageView = UIImageView(frame: CGRect(x: 10, y: 50 + ( 200 * i ) , width: 230, height: 200))

for (c,b) in photoGotArray.enumerated() {

    photoDataVarOk = UserDefaults.standard.data(forKey: b) 
    let newImageView = UIImageView(frame: CGRect(x: 10, y: 50 + ( 200 * c), width: 230, height: 200))
    newImageView.viewWithTag(c)
    newImageView.image = UIImage(data: photoDataVarOk!)
    self.imageScroll.addSubview(newImageView)
}

Why do I get unwanted animation when adding a subview to my scrollview?

I wish this helpful for you If the animateWithDuration:... call is on the stack, anything you do that is animatable will be animated. Set a breakpoint on your addSubview: call and see what's up the stack.
