[[[UINavigationBar appearance] setTitleView:button]

I tried to set title view as button for all navigation item using above line of code but it is not working.How can I set title view for all navigation bars in my project by writing small code in appdelegate ?

Answer 1

Customizing the Appearance of a Navigation Bar

it is alright to modify the barStyle, tintColor, and translucent
properties, but you must never directly change UIView-level properties
such as the frame, bounds, alpha, or hidden properties directly.

For more detail you can follow apple doc UINavigationBar Class Reference

Edit ->

I solved your query

[[UINavigationBar appearance] addSubview:yourView];
