I've got problem is how can I increase UITableViewCell based on UIImage inside content.
Image from URL will be downloaded and display inside UIImageView with AlamofireImage.
I've added as follow:
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
and configure right constraint like that
Please let me know where I'm missed.

I have a problem with my UITableView sections (and their height, I guess).
Within a section header, I have a view (named cornerRadiusView) within which there are few labels. These labels have dynamic content (fetched from a REST service). So whenever a UILabel height is increased, I am increasing the height of the cornerRadiusView to properly accommodate the content.
The problem is, all this works as expected only when I scroll my tableView. Till then, the heights are improper.
Here I am posting GIF to show what's going on.
I can give more details and code as needed. Could someone please look at where there is a problem?
You can use below functions
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
And reload table view in below method
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
tableview.reloadData()
}
And if you are maintaining dynamic height then manage those height in cell
override func layoutSubviews()
{
}
I wanna get like this:
I am using a custom UITableViewCell where I download images asynchronously with Alamofire from within the cell.
The images appear after the cell was loaded from within the UITableviewController.
Some images do not exist. So the cell should be collapsed and show only text if there is no image present.
How can I achieve to resize the cell when the image is present?
(All images should appear in the same height and full width.
What I already tried is something like this in my TableViewController:
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 80
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
But the result is pretty ugly:
I am writing an iOS app.
User types in movie search keywords and it fetches data from omdbapi.com and displays movies in tableview.
Issue is that that table view cell isn't getting displayed correctly.

I tried using every autolayout method but, its not working.
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension;
}
You need to set estimate method for table height too. so place these method for height calculation and also check your cell constraint.
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
Hope this will help you.
I am trying to make dynamic image height in tableview. i used SDWebImage to download image from URL. but it's not working on few initial cell
Here below methods that i wrote
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let shareDetailCell = tableView.dequeueReusableCell(withIdentifier: THShareDetailTableViewCell.className, for: indexPath) as! THShareDetailTableViewCell
shareDetailCell.selectionStyle = UITableViewCellSelectionStyle.none
shareDetailCell.likeButton.tag = indexPath.row
//to set image dynamic height
shareDetailCell.selectionStyle.socialPostImage.sd_setImage(with: URL(string: socialInteraction[indexpath.row].largeImageUrl), placeholderImage: nil, options: .retryFailed) { (image, error, imageCacheType, imageUrl) in
if image != nil {
let imgHeight = (image?.size.height)!
shareDetailCell.heightConstraintSocialImage.constant = (imgHeight * (self.socialPostImage.frame.size.width/imgHeight))
}else {
print("image not found")
}
}
return shareDetailCell
}
From your code work I found two things ,
Never return UITableViewAutomaticDimension from estimatedHeightForRowAt because estimated height is never be Automatic otherwise x-code does not understand what height it should need to return. Sometimes it works but not considered as a good practice.
You fetching the Images in the cellForRowAt method that means upto you fetch the image the height of cell is already set. So your cell images that height only.UITableViewAutomaticDimension works when system knows the height of that cell at the heightForRowAt method not after that.
Suggestion for your problem.
Once you fetch the data and then reload your tableView so that cell height is adjusted according to the image height. You can do this in paging also.
I am new to IOS and anyhow i have implemented the FZAccordion from HERE. Now my problem is when i have a long text in header section and cells it goes beyond the bounds.So how can i get rid of this problem so that no matter how long is the text it always fits in the screen.
Thank you.
You can use
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
override func tableView(_ tableView: UITableView,estimatedHeightForRowAtindexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension}
This will automatically resizes your text in your cells.
