UI 导航控制器

导航控制器

//1,导航控制器在Appdelegate.h里的启动方法里写:

//  AppDelegate.m

//  Tank_UI_07

#import "AppDelegate.h"

#import "ViewController.h"   //导入

@interface AppDelegate ()

@end

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    ViewController *viewController = [[ViewControlleralloc]init];

    

    //有一个viewController才能有导航控制器

//    self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];   //重新定义一个windows

    

    

    

    self.window.rootViewController = [[UINavigationControlleralloc]initWithRootViewController:viewController];//导航控制器

    [self.windowmakeKeyAndVisible];   //拿到根视图windows(第二层,第一层是mainScreen)

    

    

    //iOS7.0之后通常在appdelegate设置导航栏的颜色

    

    //设置导航栏bar的颜色

    [[UINavigationBarappearance] setBarTintColor:[UIColorcolorWithRed:34/255.0green:199/255.0blue:255/255.0alpha:1]];

    

    //设置导航栏title字体颜色,大小

    [[UINavigationBarappearance] setTitleTextAttributes:[NSDictionarydictionaryWithObjectsAndKeys:[UIColorwhiteColor], NSForegroundColorAttributeName,[UIFontsystemFontOfSize:18],NSFontAttributeName,nil]];

    

    

    

    [[UINavigationBarappearance]setTintColor:[UIColorwhiteColor]];

    

    

    return YES;

}

也可以在mainStoryboard里设置:

//在ViewController.m里

这里涉及Push推动跳转的方法:
