@interface ViewController ()

- (IBAction)search:(id)sender;

@property (weak, nonatomic) IBOutlet UITextField *strUrl;

- (IBAction)jumpApp:(id)sender;

@end

@implementation ViewController

- (void)viewDidLoad {

    [super viewDidLoad];

    // Do any additional setup after loading the view, typically from a nib.

}

- (void)didReceiveMemoryWarning {

    [super didReceiveMemoryWarning];

    // Dispose of any resources that can be recreated.

}

#pragma mark 跳轉到網頁

- (IBAction)search:(id)sender {

    NSString *str = _strUrl.text;

   [self openUrl:str];

}

//跳轉到別的安裝的應用---7.0之前須要增長一個白名單:增長方法，在plist文件裏面增長一個LSApplicationQueriesSchemes節點，類型是array，在數組裏面增長一個子項目，將你要跳轉的那個應用設置的 URL Schemes填寫在裏面

//URL Schemes 設置方法，被跳轉的應用裏點擊項目名稱-->info-->底部URL Types點開，在裏面增長一項而且給URL Schemes添加一個名稱

//7.1 以後須要在給identifier 設置一個名稱，而且跳轉的應用 General-->Bundle identifler須要設置一個名稱，而且要和被跳轉應用identifier裏面設置的名稱一致

#pragma mark 跳轉到app

- (IBAction)jumpApp:(id)sender {

    NSString *str = @"app://name=jack";

    [self openUrl:str];

    

}

- (void) openUrl : (NSString *) strUrl{

    NSURL *url = [NSURL URLWithString:strUrl];

    UIApplication *app = [UIApplication sharedApplication];

    //判斷手機裏面是否安裝該應用

    if (![app canOpenURL:url]) {

        NSLog(@"沒法打開%@,請確保應用已正確安裝",url);

    }else{

        //打開應用

        [app openURL:url];

    }

}

@end

=================被跳轉的app=================

//AppDelegate 裏面添加以下代碼

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

    self.window.backgroundColor = [UIColor whiteColor];

    self.viewcon = [[ViewController alloc]init];

    self.window.rootViewController = self.viewcon;

    return YES;

}

//從另一個app 裏面跳過來時會執行的方法

- (BOOL) application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options{

    self.viewcon.label.text=[NSString stringWithFormat:@"%@",url];//給頁面裏面的控件賦值

    return YES;

}
