一、基本配置以及主体框架

项目主体架构：用tabBarController为根控制器,四个navigationController为它的子控制器，这四个navi管理各自的VC.项目文件夹类型：用MVC的方式分类,大概为四个模块,在ohter文件夹中放入必要的分类文件跟扩展文件以及常用第三方,创建pch文件,设置路径

拖入启动图片跟appIcon,初始化window,设置根VC为自定义的tabBarVC,创建子控制器时,抽出一个方法

/**
* 初始化子控制器
*/
- (void)setupChildVc:(UIViewController )vc title:(NSString )title image:(NSString )image selectedImage:(NSString )selectedImage

{

// 设置文字和图片 vc.tabBarItem.title = title;vc.tabBarItem.image = [UIImage imageNamed:image];vc.tabBarItem.selectedImage = [UIImage imageNamed:selectedImage];vc.view.backgroundColor = [UIColor colorWithRed:arc4random_uniform(100)/100.0 green:arc4random_uniform(100)/100.0 blue:arc4random_uniform(100)/100.0 alpha:1.0];// 包装一个导航控制器, 添加导航控制器为tabbarcontroller的子控制器UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:vc];[self addChildViewController:nav];

}

后面带有UI_APPEARANCE_SELECTOR的方法, 都可以通过appearance对象来统一设置

// 通过appearance统一设置所有UITabBarItem的文字属性NSMutableDictionary *attrs = [NSMutableDictionary dictionary];attrs[NSFontAttributeName] = [UIFont systemFontOfSize:12];attrs[NSForegroundColorAttributeName] = [UIColor grayColor];NSMutableDictionary *selectedAttrs = [NSMutableDictionary dictionary];selectedAttrs[NSFontAttributeName] = attrs[NSFontAttributeName];selectedAttrs[NSForegroundColorAttributeName] = [UIColor darkGrayColor];UITabBarItem *item = [UITabBarItem appearance];[item setTitleTextAttributes:attrs forState:UIControlStateNormal];[item setTitleTextAttributes:selectedAttrs forState:UIControlStateSelected];

由于tabBar中间的按钮特殊性,考虑自定义tabBar的方式(由于tabBar是只读属性,故用kvc自定义)

[self setValue:[[XMGTabBar alloc] init] forKeyPath:@"tabBar"];

在自定义的tabBar文件里面,由于是通过代码创建,只需重写- (instancetype)initWithFrame:(CGRect)frame方法,在此方法里面创建中间的发布按钮，并layoutSubViews方法里面设置坐标

在设置导航栏左边按钮中,发现创建按钮的代码可以抽出来

// 设置导航栏标题self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"MainTitle"]];// 设置导航栏左边的按钮UIButton *tagButton = [UIButton buttonWithType:UIButtonTypeCustom];[tagButton setBackgroundImage:[UIImage imageNamed:@"MainTagSubIcon"] forState:UIControlStateNormal];[tagButton setBackgroundImage:[UIImage imageNamed:@"MainTagSubIconClick"] forState:UIControlStateHighlighted];tagButton.size = tagButton.currentBackgroundImage.size;[tagButton addTarget:self action:@selector(tagClick) forControlEvents:UIControlEventTouchUpInside];self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:tagButton];

为UIBarButtonItem写一个分类

@interface UIBarButtonItem (XMGExtension)+ (instancetype)itemWithImage:(NSString *)image highImage:(NSString *)highImage target:(id)target action:(SEL)action;@end

    @implementation UIBarButtonItem (XMGExtension)    + (instancetype)itemWithImage:(NSString *)image highImage:(NSString *)highImage target:(id)target action:(SEL)action    {    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];    [button setBackgroundImage:[UIImage imageNamed:image] forState:UIControlStateNormal];    [button setBackgroundImage:[UIImage imageNamed:highImage] forState:UIControlStateHighlighted];    button.size = button.currentBackgroundImage.size;    [button addTarget:target action:action forControlEvents:UIControlEventTouchUpInside];    return [[self alloc] initWithCustomView:button];    }    @end
