Views 1307 Comment 0
후킹이라기보다 교체? ㅋㄷ
방법이 많음..
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back" style:UIBarButtonItemStyleBordered target:self action:@selector(backButtonTapped:)]; self.navigationItem.leftBarButtonItem = backButton;
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:@selector(backButtonTapped:)]; self.navigationItem.leftBarButtonItem = backButton;
UIImage *backButtonImage = [UIImage imageNamed:@"back_arrow.png"]; UIButton *leftBarButton = [UIButton buttonWithType:UIButtonTypeCustom]; // Setting the image for the back button [leftBarButton setBackgroundImage:backButtonImage forState:UIControlStateNormal]; [leftBarButton addTarget:self action:@selector(backButtonTapped:) forControlEvents:UIControlEventTouchUpInside]; // setting the frame for the back button leftBarButton.frame = CGRectMake(0, 0, 65, 32); // setting the custom button to navigationbars back button self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:leftBarButton];
