建立UIImagePickerController 字体

 // 建立图片选择器
            UIImagePickerController *picker = [[UIImagePickerController alloc] init];
            picker.sourceType =UIImagePickerControllerSourceTypePhotoLibrary;
            picker.allowsEditing = YES;
            picker.delegate = self;

//设置导航栏背景颜色spa

picker.navigationBar.barTintColor = HexRGB(0x4294FE);代理

//设置右侧取消按钮的字体颜色code

picker.navigationBar.tintColor = [UIColor whiteColor]; // 以富文本方式更改[picker.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor], NSFontAttributeName:[UIFont boldSystemFontOfSize:18]}];orm

           [self presentViewController:picker animated:YES completion:nil];

右侧取消按钮的字体方式无效可以使用代理方法blog

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    [viewController.navigationItem.rightBarButtonItem setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor], NSFontAttributeName:[UIFont systemFontOfSize:18]} forState:UIControlStateNormal];
    
    [viewController.navigationItem.leftBarButtonItem setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor], NSFontAttributeName:[UIFont systemFontOfSize:18]} forState:UIControlStateNormal];
}
