table cell not auto resizing according to uiimageview height - ios

UIImageView height width is set to fillparent. and using follwing code to auto resize table cell.
DiscountTableView.Source = new DiscountsTVS(discounts);
DiscountTableView.EstimatedRowHeight = 164;
DiscountTableView.RowHeight = UITableView.AutomaticDimension;
but i am getting following output
not sure what i am doing wrong.

You can check working example here i hope this is useful for you.Dynamic hieght of tableviewcell

If you used UITableView.AutomaticDimension ,you need to add constraints in the xib or in the code

Stretchable Header View in UITableView with dynamical height

How can I manage the height of the TableViewHeader based on the lines of an UILabel?
I followed this guide but I can't manage the header height dynamically.
In the guide it is fixed to a fixed size to which I tried to add the height of the label but it doesn't work.
I would prefer to use a tableview and not a scrollview as the data is populated dynamically.
I also tried to modify the constraints of the label dynamically, but when scroll the view of the label is stretched and not the image.
Add this in viewDidLoad:
self.tableView.sectionHeaderHeight = UITableViewAutomaticDimension;
self.tableView.estimatedSectionHeaderHeight = 25;
After that just give correct constrains for the headerView . That's it! No need to implement heightForHeaderInSection

Auto layout cell based on subview or custom cell height

In the image. Comments has a textview that has text overflown to below 3 cells . Ideally that should not happen.
I have a tableview with custom cells as xib files and some custom cells are subviews. Please let me know how to add auto layout for this subviews or xib's.
I read many posts they suggested.below code. But it doesn't work.
In ViewDidLoad.
self.tableView.rowHeight = UITableViewAutomaticDimension
self.tableView.estimatedRowHeight = 50;
Please suggest a solution. Thank you.
It will works, but you need to update the height everytime a new character is input, so in your cellForRow, add textview.delegate = self, and in the textViewDidChange, do tableView.beginUpdate() and tableView.endUpdate(), the cell height will update correctly

how to set tablecell row height automatically based on inner view outlet?

I want to set tableview cell height automatically to show the label completely without happening like that?
Any help?
There are 2 things that you need to do:
1st thing: Set AutoLayout for it.
2nd thing: implement these code:
self.tableView.rowHeight = UITableViewAutomaticDimension
self.tableView.estimatedRowHeight = 100

Swift: Getting a Label in TableView Prototype Cell to display multiple lines (word wrap)

I'm trying to setup a tableview which each cell will have an Image on the left, a Label which overlays the image, and finally a label to the right of the image with long text in which I would like for it wrap to the next line if needed. My tableview row height is set at 65.
I have set the number of lines to 0 and set the line break to work wrap.
I even tried setting parameter programmatically in my CustomTableViewCell class:
self.materialLabel?.numberOfLines = 0
self.materialLabel.sizeToFit()
self.materialLabel?.lineBreakMode = NSLineBreakMode.ByWordWrapping
I've tried many combinations of setting constraints on my label, but it either doesn't work or affects all objects in the cell with the image and image label out of sync. The alignment constraints are not available to set.
Working with Xcode 6.3.2, Swift 1.2, and iOS 8
Thanks in Advanced!
You can use dynamic cell height ( or self sizing cell).
Basically, you create top, leading, bottom, trailing label's constraints relative to cell's contentView.
and then set
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = someValue
http://www.raywenderlich.com/87975/dynamic-table-view-cell-height-ios-8-swift
There are many ways to setup dynamic height for table cell.
If your not not using autolayout, you need to calculate table size programmatically and return using table view delegate method.
If your using autolayout, your life will be very easy. Add constraints to cell, I.e add border, width and height constraints to image. Add only 4 border constraints to image(don't add height constraint). This may not be the exact constraints, but this will give you a idea. Add following code in viewDidload
tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = someValue
This should work.
Turns out my label width was too wide. I had to anchor my imageview and the imagelabel and set the width and height before setting the constraints on my label.

UICollectionView working on iOS7 but not on iOS6

My UICollectionView cells don't get displayed on iOS6, because my delegate method cellForItemAtIndexPath doesn't get called. I suspect because of this warning:
the behavior of the UICollectionViewFlowLayout is not defined because:
the item height must be less that the height of the `UICollectionView`
minus the section inset's top and bottom values.
I don't get the warning on iOS7, and all the cells display correctly there too.
I've set my collectionView frame to height 270 in the .xib and there are no insets defined.
I've set my cell height to 270 in the .xib.
I can print out my collectionView frame at runtime and it's 271.
Also, my collectionview is actually inside a custom tableview cell.
Any ideas?
Thanks!
Try to set self.automaticallyAdjustsScrollViewInsets = NO
This was introduced in ios7 so you might want to wrap that with an ios version check, if you are supporting ios6 and below.
This fixed my problem! In my .xib, setting my Collection View Size Cell Size to a smaller value.
My setup is that I have this collectionview inside a custom tableview cell and
I do return the height of my tableview cell programatically (depending on the content). So it could be that my warnings had to do with my collectionview not fitting inside the tableview cell. So setting the initial collectionview to a smaller value fixed it.
I was on the wrong path thinking that the problem was with my collectionview and its colletionview cell.
Maybe?
self.automaticallyAdjustsScrollViewInsets = NO
actually did the trick. it also resolved my issue in swift, where the cells of a horizontal flow layout had a frame top of -32 (???) and did not fit into the collection view properly.
I found that I had to manually set self.collectionView.collectionViewLayout.itemSize in viewWillLayoutSubviews.
- (void)viewWillLayoutSubviews {
self.collectionView.collectionViewLayout.itemSize = CGRectMake(...);
}
Another possibility to generate the same trick would be to implement the method
collectionView:layout:sizeForItemAtIndexPath:
I have the same issue, in my case the size of collectionCell in storyboard is 96x96 and also under -(CGSize)collectionView:layout:sizeForItemAtIndexPath:
the solution was removing this delegate:
- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section
{
UIEdgeInsets insets = {.left = 10, .right = 10, .top = 5, .bottom = 5};
return insets;
}
And by the way this is under ios7, it's late but hope this will help some.. Cheers..
Set:
self.itemSize = CGSizeMake(1, 1);
