我们要统一所有的导航栏控制器，不能一个一个的子控制器去设置
这时我们需要自定义导航控制器来统一样式
首先新建一个继承UINavigationController的类
然后在自定义的TabBarController中设置
XMGNavigationController *nav = [[XMGNavigationController alloc] initWithRootViewController:vc];
我们就可以自定义的UINavigationController中来个性化了
- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
if (self.childViewControllers.count > 0) {
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setTitle:@"返回" forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:@"navigationButtonReturn"] forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:@"navigationButtonReturnClick"] forState:UIControlStateHighlighted];
button.size = CGSizeMake(70, 30);
button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
button.contentEdgeInsets = UIEdgeInsetsMake(0, -10, 0, 0);
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button setTitleColor:[UIColor redColor] forState:UIControlStateHighlighted];
[button addTarget:self action:@selector(back) forControlEvents:UIControlEventTouchUpInside];
viewController.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
viewController.hidesBottomBarWhenPushed = YES;
}
[super pushViewController:viewController animated:animated];
}
- (void)back
{
[self popViewControllerAnimated:YES];
}
最后分享一个在PCH中方便设置颜色的方法
#define XMGRGBColor(r, g, b) [UIColor colorWithRed:(r)/255.0 green:(g)/255.0 blue:(b)/255.0 alpha:1.0]
#define XMGGlobalBg XMGRGBColor(223, 223, 223)
