If we have the requirement to customize our navigation bar’s title then we cannot change any feature of the navigation title.

So to solve this problem we can simply create a UILabel as follows :-

UILabel *titleLabel = (UILabel *)self.navigationItem.titleView;

and then customize it according to our requirement and finally assign this titleLabel as follows :-

self.navigationItem.titleView = titleLabel;

 

Also inspite of assigning any frame value to this titleLabel you can simply use :-

[titleLabel sizeToFit];
