本文主要是介绍代码搭建记事本框架（二），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
主题设定，初始化的代码，通过执行这些代码来设置对应的navigation和barbutton的属性/** * 只执行一次的代码 */ +(void)initialize { //设置nav对应的属性. [self setNavigationBarTheme]; //设置barbutton对应的属性. [self setBarButtonTheme ]; }
对应属性的设定
+(void)setBarButtonTheme { // UIBarButtonItem *appearence = [UIBarButtonItem appearance]; NSMutableDictionary *textAttrs =[[NSMutableDictionary alloc]init]; textAttrs[NSForegroundColorAttributeName] = [UIColor orangeColor]; textAttrs[NSFontAttributeName] = [UIFont systemFontOfSize:15]; [appearence setTitleTextAttributes:textAttrs forState:UIControlStateNormal]; NSMutableDictionary *highTextAttrs =[[NSMutableDictionary alloc]init]; highTextAttrs[NSForegroundColorAttributeName] = [UIColor redColor]; highTextAttrs[NSFontAttributeName] = [UIFont systemFontOfSize:15]; [appearence setTitleTextAttributes:highTextAttrs forState:UIControlStateHighlighted]; NSMutableDictionary *disableTextAttrs =[[NSMutableDictionary alloc]init]; disableTextAttrs[NSForegroundColorAttributeName] = [UIColor grayColor]; disableTextAttrs[NSFontAttributeName] = [UIFont systemFontOfSize:15]; [appearence setTitleTextAttributes:disableTextAttrs forState:UIControlStateDisabled]; //为了让按钮的背景消失，可以设置一张完全透明的背景图片 [appearence setBackgroundImage:[UIImage imageNamed:@"navigationbar_button_background"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; } +(void)setNavigationBarTheme { UINavigationBar *appearence = [UINavigationBar appearance]; NSMutableDictionary *textAttrs= [NSMutableDictionary dictionary]; textAttrs[NSFontAttributeName] = [UIFont systemFontOfSize:20]; textAttrs[NSForegroundColorAttributeName] = [UIColor blackColor]; [appearence setTitleTextAttributes:textAttrs]; }
定义为类方法，容易调用。
最重要的方法还是重载的push方法
-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated { if (self.viewControllers.count>0) { //如果push进来的不是栈底控制器的话 viewController.hidesBottomBarWhenPushed = YES; viewController.navigationItem.leftBarButtonItem = [UIBarButtonItem itemWithImage:@"navigationbar_back" highImage:@"navigationbar_back_highlighted" target:self action:@selector(back)]; viewController.navigationItem.rightBarButtonItem = [UIBarButtonItem itemWithImage:@"navigationbar_more" highImage:@"navigationbar_more_highlighted" target:self action:@selector(more)]; } [super pushViewController:viewController animated:YES]; }
push中的来设定对应的属性，包括对应的背景和高亮背景点击时间对应的响应函数。
设定对应的按钮点击的响应内容。
-(void)more
{
[self popToRootViewControllerAnimated:YES];
}
-(void)back
{
[self popViewControllerAnimated:YES];
}
