QUESTION
I have used MMPlayerView
(GitHub link here) to add videos into a collection view, in the collection view the image gets replaced by a video in the code (from the demo). I took the MMPlayerView
's demo project and changed stuff to fit my needs and then implemented it into my project to get something like this show in this video.
Now I'd like to obviously move the collection view up towards the buttons at the top of the screen, and later on I will use multiple collection views like that to get the style of the app store more like, just showing videos. Since I took the code from the demo I'm not too sure on some things, when I copied the project's demo the collection view was made for scrolling through it vertically, so it takes up the whole screen, so the collection view was constrained to the bottom of the view:
Which causes this to show in the app (I don't understand why it's so far away from the top when its constrained by 10 points):
Now I want to obviously want to remove the bottom constraint and constrain it by it's height instead so I can have multiple collection views, (probably through the use of table views), so I removed the constraint to the bottom of the view and added a height constraint for 250 points:
Which caused the app to look like this:
Why?? I'm guessing it has something to do with this part of the view controller code:

Change the height value in sizeForItemAt
to the height of your collection view (250

QUESTION
How do you properly send data to a custom data NSObject class for a collection view? My variables are always returning as nil.
I have a splash screen in it's own view Controller. When all the data I want loaded has finished loading from firebase, I go to the main screen of the app via performSegue(withIdentifier:)
, here's the code for the code in question from the SplashScreenViewController
:
ANSWER
Answered 2020-Jan-19 at 22:58You have implemented DemoSource
as a singleton, which means that it gets instantiated the first time that you reference DemoSource.shared
. This is in getDatabaseReference
. When it is instantiated url
has its initial value (""), so that is what gets added to the the demoData
array.
You don't need an initialiser.
You do need a function to add data to the demoData
array.
QUESTION
I have no idea why this is happening, I had a different Xcode project with this exact same collection view just to test things out and make it and I've finished making it and it works very well in that project. Then I moved all the code and items over to my main Xcode project and the collection view just isn't showing in my view controller when I play the app.
How do you debug collection views? The two: playerCollect?.cellForItem(at: path)
and playerCollect.indexPathForItem(at: p)
both return nil if that's an issue? I don't know. I might've not connected everything back together once I moved it over to my main project, but yet again how would you find that out? Here's my full code for the viewController containing the UICollectionView:
ANSWER
Answered 2020-Jan-17 at 11:10Did you give the collection view's delegate and data source at this view controller?
QUESTION
I have a collection view that shows a group of videos of whatever data object I pass it. When you press on one of the videos in the content view then a new view (DetailViewController) get's presented and the video gets shown in a more detailed view. In that DetailViewController there's a back button that dismisses the view and puts you back to the main page with the collection view - which is when the crash happens, when I go from that 'DetailViewController' back the main view controller.
Everything works perfectly when the collection view's 'scroll direction' is set to vertical, but when I set it to horizontal (which is what I want), it crashes like explained above.
The crash is:
Unexpectedly found nil while unwrapping an Optional value
and the source is:
...ANSWER
Answered 2020-Jan-16 at 20:53It is bad practice to use the forced optional operator !
as it will often lead the error message you described. Your findCurrentPath
calculation has not been updated for horizontal movement. First, change your findCurrentPath
method to (what I believe you are trying to achieve):
