ios - selector is not called for navigationitem barbutton -

after set right bar navigation button custom view, selector never called when button pressed. here code:

uiimageview *navview = [[uiimageview alloc] initwithimage:[uiimage imagenamed:@"notification_alert.png"]]; navview.frame = cgrectmake(0, 0, 40, 40);  self.navigationitem.rightbarbuttonitem = [[uibarbuttonitem alloc] initwithcustomview:navview]; [self.navigationitem.rightbarbuttonitem settarget:self]; [self.navigationitem.rightbarbuttonitem setaction:@selector(btnclick:)]; 

the button appears correctly selector never called. appreciated!

-(ibaction)btnclick:(id)sender {     nslog(@"nav button clicked"); } 

from documentation init(customview:):

the bar button item created method not call action method of target in response user interactions. instead, bar button item expects specified custom view handle user interactions , provide appropriate response.

see uibarbuttonitem class reference more information.

a workaround use uibutton custom background image custom view, instead of uiimageview. then, add target , action button.

uibutton *button = [uibutton buttonwithtype:uibuttontypecustom]; button.frame = cgrectmake(0, 0, 40, 40); [button setbackgroundimage:[uiimage imagenamed:@"background.png"] forstate:uicontrolstatenormal]; [button addtarget:self action:@selector(btnclick:) forcontrolevents:uicontroleventtouchupinside]; uibarbuttonitem *barbuttontem = [[uibarbuttonitem alloc] initwithcustomview:button];
