ios - Trouble changing background image of navigationbar back button -

-

this question has answer here:

i believe have tried other solutions matter.

i use following code change background image of navigationbar backbutton.

uiimage *image = [uiimage imagenamed:@"standard_bt.png"];         [[uibarbuttonitem appearance] setbackbuttonbackgroundimage:image forstate:uicontrolstatenormal barmetrics:uibarmetricsdefault];

this makes button appear this:

enter image description here

without code, appears this:

enter image description here

now, background image first picture, backbutton shape of second picture.

note: achieve without having modify image named "standard_bt.png"

how do that? possible?

you have done right thing.

ios sdk doesn't provide convenience method change shape of uiimage object according standard backbutton's shape.

that said, answer is: no, can not realize shaped backbutton customization without changing button's background image itself.
