If you don't mind,can you push image array that include multiple images in uiscrollview with Page Control.I m struck at this.

Thanks you.really love to learn your scrollview.Please help

Thanks for the nice example of image zooming with auto layout.
I want to retain the zoom level on orientation change. please help me to achieve this.

It seems to work on iPad when its horisontal, but not i portrait mode :-(

Thanks for the awesome example. It works awesome for me. One thing i noticed though is the fact that when you try to make your current project compatible with this example you have to set the Intrinsic Size property of the UIImageView in the Storyboard to Placeholder. Maybe something worth mentioning in the ReadMe file.

Thanks again for making this example public

First off thanks for this example code. It's the most concise and best solution I've seen for getting zooming to work consistently with auto layout. I really appreciate.

So, I'm probably just missing something simple, but when I pinch in and release, the image view just snaps back to its starting position. I thought this was controlled by changing the minimum zoom scale, but when I mess with that in updateZoom(), it doesn't work the way I expect.

In other words, how can I make the example zoom out as well as in?

Thanks again.

I tried to reproduce your setup in my existing project.

I had a problem with two of the layout constraints, namely:

• Scroll View.Top equals Top Layout Guide.Top
• Scroll View.Bottom equals Bottom Layout Guide.Bottom

In the first case, the constraint's "First Item" is set to "Scroll View.Top". If I click the drop-down menu, all options (including the selected "top") are grayed out:

(see the tooltip warning).

Similarly, "Second Item" is set to "Top Layout Guide.Top". If I click the menu, all the options except "Bottom" (including the selected one, "Top") are grayed out:

(Something exactly analogous happens for the second constraint listed above)

The only way I found to reproduce your constraints was to enter them directly as XML in the storybpard's source code. Of course I had to change the IDs of the items involved in each constraint to match those of the view and scroll view of my storyboard (which is a total pain).

(Ideally, I would have just copy/pasted your demo project's storyboard as-is, but the existing view controller where I wanted to implement scrolling was already setup with lots of other outlets.)

Perhaps there's an alternative (but legal) set of constraints that enables the same functionality?
(I'm no autolayout expert )

Thankfully, I got panning and zooming of the image view to work.
