Change the cancle of the system camera Uiimagepickercontroller navigation bar to the Cancel button

First: Implement Navigationcontroller agent

-(void) Navigationcontroller: (uinavigationcontroller *) Navigationcontroller Willshowviewcontroller: (uiviewcontroller *) Viewcontroller animated: (BOOL) animated

{

UIButton *cusbtn = [[UIButton alloc]initwithframe:cgrectmake(0, 0, (+)];

[Cusbtn settitle:@ " cancel " forstate:(uicontrolstatenormal)];

Cusbtn. backgroundcolor = [uicolor redcolor];

[Cusbtn addTarget:self action:@selector(click) forcontrolevents:( uicontroleventtouchupinside)];

uibarbuttonitem *btn = [[uibarbuttonitem alloc] initwithcustomview: cusbtn];

[Viewcontroller. Navigationitem setrightbarbuttonitem: btn animated:NO];  

}

Second: Implement the click Method to complete; Imagepicker as a weak reference

@property (nonatomic, weak) Uiimagepickercontroller *imagepicker;

-(void) click{

[self imagepickercontrollerdidcancel:self. Imagepicker];

}
