Display issues in UITableViewController on iOS 10

[svenniemann]

Notifications are display below the Navigation Bar with empty space on top (that space should be behind the navigation bar I guess)

I use the Objective C version. So far this issue only appeared on iOS 10 in an UITableViewController. In UIViewController it works fine.

Can you please post a screenshot?

[svenniemann]

sure!

Does this happen on a blank slate project with a simple table view controller?

[svenniemann]

I will check this asap. So, you could not reproduce it I guess?

[isadon]

To be honest I haven’t had time yet to check. But considering you are reporting this, shouldn’t be hard for you to do 🙂.

Just test it in a new clean project with just a tableviewcontroller in a navigation controller. Same result:

iOS 11 + 12 work fine

I looked into this and will post a fix soon but I honestly believe this is an iOS bug.

RMessage uses the layoutGuide properties of its superview for sizing its height. By default tableViews have the property automaticallyAdjustsScrollViewInsets set to true which tells any container views such as nav controllers to inset the tableview to start below the nav bar.

The issue though is that the Navbar offsets the top layout guide of the the tableview downward by the size of the nav bar (64pts). So now the top of the top layout guide is at the bottom of the nav bar and the bottom of the top layout guide is 64pt below. RMessage uses the bottom of the top layout guide for sizing/spacing. Given that its in a place where its not expected (64pts below the nav) thats why it looks bigger as in your screenshot.

Thanks for analysing the issue! I decided to use a different library (which also adds the banners to the UIWindow, so they always stay on screen). So you don't need to provide a fix just for me.
Would have used your new Swift version, but I need iOS 10 support.

Yea I’m looking into making sure the messages stay on the screen as well. Whats interesting is some people (maybe not a lot) may want the message to get pinned to the view as it does now as animations look different that way.

The fix for this issue and “presenting on top” will be added soon. Thanks for reporting 👍.

Update 10.23.2018.17.20.50 : Ok.. It seems that the issue with RMessage not staying on top of the tableview is limited to before iOS 11 as well. On iOS 11 and up the tableView scrolls independently of RMessage.

By the way.. Alternatively try displaying RMessage like this from the UITableViewController:

[RMessage showNotificationInViewController:self.parentViewController title:@"Test" subtitle:nil type:RMessageTypeCustom customTypeName:@"error" callback:nil];

and RMessage will display on top of the UITableViewController. Then you can scroll the tableView and RMessage will stay on top. By default this isn't necessary but due to this issue with iOS 10 it's a workaround.

Bugfix added to 2.x.x_develop branch. Please retest.

[svenniemann]

I will test it tonight.

With "... so they always stay on screen" I meant that they stay on screen when pushing or popping to another ViewController

[isadon]

Cool. If RMessage is not picking the right view controllers view to add itself to use showNotificationInViewController:, you should be able to get it to stay behind.

@svenniemann any update?

Closing Issue..
