如何在iPhone中自定义Email Composer的导航栏

Question

How can I change the image of Bar Button of emailcomposer in iPhone app? I am able to change the image of the Navigation Bar but I also have to change the image of Send and cancel button.

Answer 1

the composer is presented modally as rootviewcontrolelr of a navigation controller.

If you change properties of UINavigationCar as well UIBarButtonItem with appearance , it should do the trick

UIBarButtonItem *barbuttonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonItemStyleBordered target:nil action:nil];

if ([barbuttonItem respondsToSelector:@selector(setTintColor:)]) {
    [[UIBarButtonItem appearance] setTintColor:kUIBarButtonItemTitleColor];
}

But keep in mind that this will change all bar button items not only the ones in mail composer.

Answer 2

尝试通过mailComposeViewController.navigationBar.items访问它们，这是一个条形项的数组。
