Dynamically resize UITextView height - objective-c

Question

I have a static UITableViewCell that contains a UITextView (that dynamically gets resized based on the content it has,) and a UIView.
The cell's height dynamically changes based on the height of the textView and the view.
Here is my code:
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
[self textViewFitToContent:textView];
[self.tableView beginUpdates];
[self.tableView endUpdates];
[self scrollToLocation:textView];
return YES;
}
- (void)textViewFitToContent:(UITextView *)textView
{
textView.scrollEnabled = YES;
CGFloat fixedWidth = textView.frame.size.width;
CGSize newSize = [textView sizeThatFits:CGSizeMake(fixedWidth, MAXFLOAT)];
CGRect newFrame = textView.frame;
newFrame.size = CGSizeMake(fmaxf(newSize.width, fixedWidth), newSize.height);
textView.frame = newFrame;
}
- (void)scrollToLocation: (UITextView *)textView
{
UIView *parentView = textView.superview;
while (![parentView isKindOfClass:[UITableViewCell class]]) {
parentView = parentView.superview;
}
NSIndexPath *indexPath = [myTableView indexPathForCell:(UITableViewCell *)parentView];
[myTableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES];
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
int padding = 48;
if (indexPath.section == 0 && indexPath.row == 0)
{
return 163;
}
else if (indexPath.section == 1 && indexPath.row == 0) {
return textView1.frame.size.height + self.view1.frame.size.height + padding;
}
else if (indexPath.section == 1 && indexPath.row == 1) {
return textView2.frame.size.height + self.view2.frame.size.height + padding;
}
else if (indexPath.section == 1 && indexPath.row == 2) {
return textView3.frame.size.height + self.view3.frame.size.height + padding;
}
else if (indexPath.section == 1 && indexPath.row == 3){
return textView4.frame.size.height + self.view4.frame.size.height + padding;
}
return 44;
}
Problem
The problem is, when I type in the first textView (it happens to every letter I type,) all other textView's height becomes smaller. If I type in any other textViews, (not the first one,) the first textViews height becomes bigger, and all other textViews height becomes smaller.

Answer 1

Give each textView a tag. If they're in TableViewCells...make the indexPath.row the tag for each textView. In your UITextViewDelegate methods. Use an IF ELSE and do something like
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
if (textView.tag == 1) {
[self textViewFitToContent:textView];
[self.tableView beginUpdates];
[self.tableView endUpdates];
[self scrollToLocation:textView];
}
if (textView.tag == 2) {
[self textViewFitToContent:textView];
[self.tableView beginUpdates];
[self.tableView endUpdates];
[self scrollToLocation:textView];
}
if (textView.tag == 3) {
[self textViewFitToContent:textView];
[self.tableView beginUpdates];
[self.tableView endUpdates];
[self scrollToLocation:textView];
}
return YES;
}
