I have an UITableViewController that contains a custom cell. Each cell was created using a nib and contains a single non-scrollable UITextView. I have added constraints inside each cell so that the cell adapts its height to the content of the UITextView. So initially my controller looks like this :
Now I want that when the user types something in a cell its content automatically adapts. This question has been asked many times, see in particular this or the second answer here. I have thus written the following delegate in my code :
- (BOOL) textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString*)text {
[self.tableView beginUpdates];
[self.tableView endUpdates];
return YES;
}
However it leads to the following strange behavior : all constraints are ignored and all cells height collapse to the minimal value. See the picture below:
If I scroll down and up the tableView in order to force for a new call of cellForRowAtIndexPath, I recover the correct heights for the cells:
Note that I did not implement heightForRowAtIndexPath as I expect autoLayout to take care of this.
Could someone tell me what I did wrong or help me out here ? Thank you very much !
