Multiple line UIlabel in UItableviewcell using Autolayout

Question

I have set setMaXPreferredLayoutWidth to UILabel and added all the required constraints to the UIlabel now I can see multiline UIlabel in my UItableviewcell but my problem is I am getting extra padding at the top and bottom of my UIlabel based on MaxpreferredLayoutWidth value.

When I set the MaxPreferreLayoutWidth to 200 I get this

When I set the MaxPreferreLayoutWidth to 100 I get this

In general UIlabel height depends based on preferredMaxLayoutWidth. Can any one say me how to remove this extra padding and render the exact height of UIlabel?

We have to set the tableviewcell's frame while calculating the height of the cell in heightForRowAtIndexPath
Ex:

[tableViewCell setFrame:CGRectMake(0, 0, CGRectGetWidth(self.tableView.bounds), CGRectGetHeight(tableViewCell.bounds))];

and then in layoutSubviews method of UItableviewcell we have to set the preferredMaxLayoutwidth
Ex:

[self.multilineLabel setPreferredMaxLayoutWidth:CGRectGetWidth(self.bounds)];
