What is the default height of UITableViewCell?

I thought this information would have been easier to find :-)
What is the default height of a UITableViewCell? It looks like 44 pixels, but I'd prefer to be sure.

Solution 1 - Ios
It's 44 pixels. Definitely. I'll never forget that number.
44px is also the default height for UIToolbar and UINavigationBar. (Both switch to 32px when autorotated to landscape orientation.)
Solution 2 - Ios
If you want the default dimension on any device you can use: UITableViewAutomaticDimension
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return UITableViewAutomaticDimension;
}
Although 44 pixels is currently the default this is a useful method if your app relies on having the default value set.
Solution 3 - Ios
When style = UITableViewStyleGrouped, the default height of the top & bottom cells is actually 45.0f (not 44.0f). And, if the grouped table is only one row the cell height will be 46.0f.
Solution 4 - Ios
If you want to calculate this on the fly, just allocate a dummy table cell and read off its height
UITableViewCell *cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];
int height = cell.frame.size.height ;
This way you defend against changes in future versions of iOS, although I suppose that is unlikely.
Solution 5 - Ios
In Swift 4 and Swift 5 simply use:
UITableView.automaticDimension
Using 44px won't suffice because it will vary with different screen pixel densities.

"When style = UITableViewStyleGrouped, the default height of the top & bottom cells is actually 45.0f (not 44.0f). And, if the grouped table is only one row the cell height will be 46.0f." It's wrong!! 44.0f in fact! I just test it!

That sounds about right. But to be sure you could load up Interface builder, put in a UITableViewCell into the project then check the size properties in the Inspector window. I do not have my MacBook with me right now so I cannot check. But if you don't get a better answer from someone, that is how you can check for yourself.
Solution 8 - Ios
On iOS 12 the default height on iPhone X like devices (X, XS, XS Max, XR) is 49pt.
Other devices on iOS 12 still have 44pt as default. It's a subtle difference, but it feels like a good improvement in direct comparison.
If you won't believe me, measure for yourself in this screenshot (don't forget to divide by 3)... ;)
