Change the Size of TableView Cells

(CGFloat) tableView:heightForRowAtIndexPath
A method that determines the height of each line, just like you read it.
tableView—Called before cellForRowAtIndexPath:

Enter the code here - (CGFloat) tableView: (UITableView*) tableView heightForRowAtIndexPath: (NSIndexPath*) indexPath{
// String you want to display
NSSstring* text=_objects [indexPath.row];
// Display maximum width/height
CGSize maxSize = CGSizeMake (200, CGFLOAT_MAX);
// Font Size to Display
NSDictionary*attr=@{NSFontAttributeName: [UIFont boldSystemFontOfSize:17.0]};

// Based on the above, the size required for display
CGSize modifiedSize = [text boundingRectWithSize:maxSize]
                                         options:NSStringDrawingUsesLineFragmentOrigin
                                      attributes:attributes
                                         context:nil
                       ] .size;

// Add the upper and lower 10px margins and return the larger of 70px
return MAX(modifiedSize.height+20,70);}

Perhaps TextView will not scroll.

on Storyboard - TextView does not have height constraints.Set Constraints up, down, left, and right.
- Uncheck Scrolling Enabled in TextView.
- ImageView has a height Constraint that allows custom cells to be IBOutlet properties.

The code says
- Set rowHeight and estimatedRowHeight to the table per viewDidLoaded().EstimatedRowHeight sets the approximate value for your cell.

self.tableView.rowHeight=UITableViewAutomaticDimension;
self.tableView.estimatedRowHeight=100.0;

• Set the ImageView height Constraint set on the Storyboard in tableView (tableView:cellForRowAtIndexPath:) to 0.0 if you do not want to see the image.

With AutoLayout alone, the height of TextView will automatically change, and if ImageView is not required, the height of the cell will be reduced.

If you want TextView scrollable and want to limit its height, you should override IntrinsicContentSize in the UITextView subclass.
