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)
