i have a tableview with a dynamic changing number of cells. sometimes there are 10, another time more than 20 cells.
This Tableview is on a Viewcontroller, but i have so much content on this tableview, so my tableview and all other content are on a scrollview. now i have a double scroll. on on my scrollview, and another on my tableview and this is quite uncomfortable. so how can i set the height of my tableview dynamically?
If you are using Autolayout with storyboard then set constraints of your tableview
let Count = CGFloat(dataArray.count)
constraintsTblHeight.constant = Count*100 //100 is your tablview's cell height
other wise increase this height in tablview height

I need to implement the dynamic UITableView inside dynamic UITableviewcell like the below screenshot. Also, all values are dynamic which is coming from the server.
yes exactly you need inner tableview to do this.
first you have main tableview with card layout cell this should be dynamic cell height.
in this cell you have topview, inner tableview, bottom view all this view you can take fix height as your layout i see e.g top view is 80 height, bottom view is 80 height and tableview has dynamic height based on number of cell like cell height is 100 and you have total 3 cell so table height is 300 you need to make outlet of tableview height and update it programmatically.
hope this helps you!
I used tableView inside the collectionView cell.My question is how to calculate the tableView height and set that height in collectionview cell.
NB: The table view height will be dynamic.
Please help me.
Since UITableView is a subclass of UIScrollView you can get its height by calling tableView.contentSize which will give you width and height of the table view's content
You can put KVO(observer) on contentSize of tableview, so whenever contentSize of tableview will get updated, you will get notified, at that time you can modify the height of collection view cell.
I have a UITableView with cells that have inside a UICollectionView.
Now all works great except of UICollectionViewCell scrolling i want that the height of table view cell follow the Collection view cell content.
In simple word i want scrolling in table view but not inside single cell i need to display all contents of UIcollectionViewCell without scrolling inside it.
Thanks
You have to calculate the collectionviews' heights and set a height constraint on each of them. then add top and bottom constraints from the collectionviews to their superviews (the tableviewcells / their contentviews) and let autolayout do its work.
don't forget
tableView.estimatedRowHeight = 44 // or something similar
tableView.rowHeight = UITableViewAutomaticDimension
in the controller's viewDidLoad to make the automatic row height calculation work.
I'm hiding rows that are completed in a collectionView.
I call cell.hidden = isCellHidden in cellForItemAtIndexPath when needed.
After I hide 10 rows there is plenty of empty space left and I'd like to trim down the size of the collectionView to only fit the rows that are not hidden.
The collectionView's design is kind of like a tableView.
I know with the tableView all I had to do to achieve this is set:
func section1VisibilityButton(sender: UIButton){
isCellHidden = !isCellHidden
self.tableView.reloadData()
self.tableView.contentSize.height = CGFloat(500)
}
with a collectionView when I try this it will resize it correctly but as soon as I try to scroll down it resizes itself back to the original height including the cells hidden (the cells layer is still hidden but there's tons of empty space bellow the last visible row as if they were visible)
For your issue, there are two options to change the frame of your collectionView/tableView.
If you are using autolayout, you need to create IBOutlet of bottom constraint or IBOutlet of constant height constraint of your tableView (anyone of these constraints, which you are using).
After reload tableView data you need to update constraint by calculating its height.
Suppose you are using constant height constraint and your calculated height is 150(e.g. 3 rows and 50 height of each row).
constraintTableViewHeight.constant = 150;//this will change height
self.view.layoutIfneed(); // this will apply updated constraints to whole view
If you are not using autolayout, you can manually change the height by changing tableView.frame property.
I have tableview frame height is 300. I have created one custom UITableViewCell subclass for adding to UITableView cell. When ever i adding custom cell to tableview, tableview is not increasing the height of frame. Tableview height constant like previous height 300. I want that whenever custom cell is adding the tableview height should be increase. How to resolve this?
