AutoLayout / XIB

[cemkozinoglu]

Hey awesome piece of code! Problem... When you load a card from XIB.. and move it around stuff within the card does not stay within the bounds.. hard to explain but let me send a screen show.

Are you using autolayout?

[cemkozinoglu]

Yup

[zhxnlai]

Would this post solve your problem?

[cemkozinoglu]

It would but I think I found another problem. I read another autolayout/transform suggestion which was;

Wrap everything in the view inside a new host/proxy container view.. And have the container view to set constraints.. What turned out doing that so is.. When i start dragging the Card the frame of the card gets bigger.. Thus the center changes and everything inside the card moved off the bounds.. It wasnt visible before.

I can send a screenshot so you can see what I mean.

Yes please.

Ignore the "Invite friends" button please.. that is on a higer index on the main-view not on the card-view.

So as you can see, when I have a structure like:

ViewController
|--------ZLSwipeableView
|------------------------- CardView (UIView)
|-------------- Proxy UIView (which constraints to cardView 0,0,0,0)
|-------------- Rest of the buttons/images etc...

Instead of;

ViewController
|--------ZLSwipeableView
|------------------------- CardView (UIView)
|-------------- Rest of the buttons/images etc...

I can observe that when I move the card around, card starts getting bigger. This could be Bounds vs Frame issue when you are doing your magic?

[zhxnlai]

My guess is that the frame gets bigger after rotation and the view constraints update subviews based on the rotated frame, causing unwanted behaviors. Sorry, I don't have a solution yet but I will keep an eye on it.

Are you using Bounds or Frame doing the calculations? I think it might be to do with Frame vs Bound issue. check the thread out.

[cemkozinoglu]

[zhxnlai]

I am using bounds inside ZLSwipeableView. The problem might be that Autolayout uses frame instead of bounds.

[cemkozinoglu]

Solved it.. here is the trick after adding the proxy view I mentioned above:

• (void)swipeableView:(ZLSwipeableView *)swipeableView didStartSwipingView:(UIView *)view atLocation:(CGPoint)location {
  UIView *card = view.subviews[0];
  card.translatesAutoresizingMaskIntoConstraints = YES;

  NSLog(@"did start swiping at location: x %f, y %f", location.x, location.y);
  }

So pretty much disabling autolayout when view starts moving.

Nice, I'm glad that you solved the problem!

Great advice! thanks for this, it was driving me crazy!
I implemented a contentView, and didn't need to set translatesAutoresizingMaskIntoConstraints to YES in the delegate or elsewhere. Initializing it with the parent view's bounds was enough for me.

Thanks again! Great lib.

@cemkozinoglu : Can you show me the code how you load the view from xib. I try to do the same thing but have problem while dragging, the image view is not bounded inside the card view (see screenshot)

Here are my contraints for my cardview.xib

[zhxnlai]

@peacemoon I just updated the demo app. It now includes an example that loads views from xib.

[antranapp]

@zhxnlai great, thank you

[yingmu52]

there are some constrain conflicts, any ideas ?

[zhxnlai]

@yingmu52 Thanks for reporting this issue! I just fixed it so please try the latest version of the demo app.

[yingmu52]

thanks for updating the library.. unfortunately, I still get some warnings.

[zhxnlai]

@yingmu52 are you using iOS 8? I double checked and did not get any warning

[yingmu52]

I am running 7.1.2 on my device. .

[zhxnlai]

@yingmu52 That's weird, I tested it on both iOS 7 and iOS8 simulator and it worked fine

I have put my custom view under this link, it will be great if you could test it for me. thank you :)

I have an issue where the swipeable view's frame is changed by auto-layout. but the card views have been pinned at the size before the swipeableview frame changed. Anyone know what I need to do?

there are some problems while I use this with autolayout in iOS7
