iOS Navigation 使用的一些總結

1.先說添加吧

　　AppDelegate.h

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    // 修改導航顏色
    [[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:100 green:80 blue:50 alpha:1]];
    
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    ViewController *vc = [[ViewController alloc] init];
    self.window.rootViewController = vc;
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    return YES;
}

2.自定義導航欄

系統自帶的方法
//左邊按鈕
    UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action:@selector(selectLeftAction:)];
    self.navigationItem.leftBarButtonItem = leftButton;
    
    //右邊按鈕
    UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@selector(selectRightAction2:)];
    self.navigationItem.rightBarButtonItem = rightButton;

自定義按鈕圖案

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[self scaleToSize:[UIImage imageNamed:@"myselect.png"] size:CGSizeMake(20, 20)] style:UIBarButtonItemStylePlain target:self action:@selector(Actionright:)];





//設置圖片大小
- (UIImage *)scaleToSize:(UIImage *)img size:(CGSize)size{
    // 創建一個bitmap的context
    // 並把它設置成為當前正在使用的context
    UIGraphicsBeginImageContext(size);
    // 繪制改變大小的圖片
    [img drawInRect:CGRectMake(0, 0, size.width, size.height)];
    // 從當前context中創建一個改變大小后的圖片
    UIImage* scaledImage = UIGraphicsGetImageFromCurrentImageContext();
    // 使當前的context出堆棧
    UIGraphicsEndImageContext();
    // 返回新的改變大小后的圖片
    return scaledImage;
}

設置push返回按鈕的樣式

 //push返回按鈕樣式
    UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithTitle:@"" style:UIBarButtonItemStylePlain target:nil action:nil];
    self.navigationItem.backBarButtonItem = item;
    //self.navigationController.navigationBar.tintColor = [UIColor grayColor];

自定義標題與導航欄的樣式

//修改導航欄標題字體大小和顏色,背景顏色
    [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;
    [self.navigationController.navigationBar setBarTintColor:[UIColor colorWithRed:212/255.0 green:51/255.0 blue:36/255.0 alpha:1]];
    
    [self.navigationController.navigationBar setTitleTextAttributes:@{
                                                                      NSFontAttributeName:[UIFont systemFontOfSize:17],
                                                                      NSForegroundColorAttributeName:[UIColor whiteColor]
                                                                      
                                                                      }];

這是改變最上邊電量圖標,時間等顏色

 

3.關於跳轉的一些總結:

(1).push跳轉到下一頁,會帶着自己導航欄一起跳,這里說的導航欄說的是他自定義的導航欄的屬性

NextViewController *next =[[NextViewController alloc]init];
    [self.navigationController pushViewController:next animated:NO];

(2).push跳轉到下一頁,下一頁隱藏導航欄

//隱藏導航欄
-(void)viewWillAppear:(BOOL)animated{
    self.navigationController.navigationBarHidden = YES;
}

(3).pop到前面的任何一頁面

//返回視圖根控制器
    [self.navigationController popToRootViewControllerAnimated:YES];

//pop到指定頁面
//    for (UIViewController *controller in self.navigationController.viewControllers) {
//        if ([controller isKindOfClass:[NextViewController class]]) {
//            NextViewController *A =(NextViewController *)controller;
//            [self.navigationController popToViewController:A animated:YES];
//        }
//    }

//其中的NextViewController為想要跳轉到的view

(4).present不帶導航欄的跳轉

HomeViewController *home = [[HomeViewController alloc]init];
    
    [self presentViewController:home animated:YES completion:^{
        
        NSLog(@"Login Success!");
    }];

如果是拖頁面的話

HomeViewController *home = [self.storyboard instantiateViewControllerWithIdentifier:@"home"];
    home.sessionID = self.sessionID;
    [self presentViewController:home animated:YES completion:^{
        
        NSLog(@"Login Success!");
    }];
