网页唤醒app、一个app唤醒另一个app

#####网页唤醒app: 可以通过URL Schemes唤醒某个应用。具体schemes是什么，怎么理解，可自行百度，我觉得可以将它认为是某个应用的身份标识。当然，这个标识可能不是唯一的，因为人们可以自定义它，一个人定义一个应用的schemes为myApp，另外一个人也可以定义另一个应用的schemes为myApp。

新建一个个人应用: 然后TARGETS->info->URL Types->点击"+"号，这里定义URL Schemes为openApp。 至此，若仅仅是网页唤醒应用，工作已经完成。

若在工程的info.plist文件中查看，则是:

即:URL types->item0->URL Schemes->item0 PS: URL Schemes可定义多个。

AppDelegate.m:

//
//  AppDelegate.m
//  OpenApp
//
//  Created by mac on 17/4/28.
//  Copyright © 2017年 cai. All rights reserved.
//

#import "AppDelegate.h"
#import "ViewController.h"

@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    
    ViewController *vc = [[ViewController alloc] init];
    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:vc];
    self.window.rootViewController = nav;
    
    [self.window makeKeyAndVisible];
    
    return YES;
}

//iOS8及以下这个
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    
    return YES;
}

//iOS9及以上这个
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options
{
    NSLog(@"--url: %@", url);
    
    return YES;
}

@end

Output:
2017-04-28 14:39:31.684442+0800 OpenApp[14303:3806016] --url: openapp://
复制代码

可以在URL Schemes指令: openApp后添加参数，如: openApp://www.baidu.com 则被打开的应用的输出为:

2017-04-28 14:44:21.115314+0800 OpenApp[14303:3806016] --url: openapp://www.baidu.com
复制代码

然后可取到参数，做相应操作。

效果:

#####一个app唤醒另一个app:

新建两个个人应用分别为: OpenAppA和OpenAppB，前者唤醒后者为例。另外唤醒两个已经上线的应用: 滴滴企业版和滴滴个人版。 (我的手机未安装滴滴企业版、但安装了滴滴个人版和新建的OpenAppB应用)

首先看OpenAppA应用的配置: 在其info.plist中配置:

PS: 滴滴企业版的URL Schemes为didies、滴滴个人版的URL Schemes为onetravel。我这里定义应用OpenAppB的URL Schemes为openAppB，这个可以自定义。

ViewController.m:

//
//  ViewController.m
//  OpenAppA
//
//  Created by mac on 17/4/28.
//  Copyright © 2017年 cai. All rights reserved.
//

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
    self.title = @"OpenAppA";
    
    self.view.backgroundColor = [UIColor orangeColor];
    
    [self testPushDidi];
    
}

#pragma mark -create UI
- (void)testPushDidi
{
    UIButton *btn1 = [UIButton buttonWithType:UIButtonTypeCustom];
    [btn1 setTitle:@"滴滴企业版" forState:UIControlStateNormal];
    btn1.frame = CGRectMake(10, 100, 100, 50);
    btn1.backgroundColor = [UIColor purpleColor];
    [btn1 addTarget:self action:@selector(btn1Action) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn1];
    
    
    UIButton *btn2 = [UIButton buttonWithType:UIButtonTypeCustom];
    [btn2 setTitle:@"滴滴个人版" forState:UIControlStateNormal];
    btn2.frame = CGRectMake(10, 200, 100, 50);
    btn2.backgroundColor = [UIColor purpleColor];
    [btn2 addTarget:self action:@selector(btn2Action) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn2];
    
    
    UIButton *btn3 = [UIButton buttonWithType:UIButtonTypeCustom];
    [btn3 setTitle:@"openAppB" forState:UIControlStateNormal];
    btn3.frame = CGRectMake(10, 300, 100, 50);
    btn3.backgroundColor = [UIColor purpleColor];
    [btn3 addTarget:self action:@selector(btn3Action) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:btn3];
}

- (void)btn1Action
{
    NSString *str = @"didies://";
    NSURL *url = [NSURL URLWithString:str];
    if ([[UIApplication sharedApplication] canOpenURL:url]) {
        
        [[UIApplication sharedApplication] openURL:url];
    }else {
        NSLog(@"can not--滴滴企业版");
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://itunes.apple.com/us/app/di-di-qi-ye-ban-mei-hao-shang/id1061542715?mt=8"]];
    }
}

- (void)btn2Action
{
    NSString *str = @"onetravel://";
    NSURL *url = [NSURL URLWithString:str];
    if ([[UIApplication sharedApplication] canOpenURL:url]) {
        
        [[UIApplication sharedApplication] openURL:url];
    }else {
        NSLog(@"can not--滴滴个人版");
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://itunes.apple.com/cn/app/di-di-da-che-da-che-shen-qi/id554499054?mt=8"]];
    }
}

- (void)btn3Action
{
    NSString *str = @"openAppB://";
    NSURL *url = [NSURL URLWithString:str];
    if ([[UIApplication sharedApplication] canOpenURL:url]) {
        
        [[UIApplication sharedApplication] openURL:url];
    }else {
        NSLog(@"can not");
    }
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


@end

图:

OpenAPPB应用:

只需要配置自己的URL Schemes为openAppB即可。

效果:

• 点击滴滴企业版按钮

因为未安装滴滴企业版，则进入了else跳转到App Store的滴滴企业版下载页面；

Output:

2017-04-28 16:04:36.825447+0800 OpenAppA[14375:3822064] -canOpenURL: failed for URL: "didies://" - error: "The operation couldn’t be completed. (OSStatus error -10814.)"
2017-04-28 16:04:36.825635+0800 OpenAppA[14375:3822064] can not--滴滴企业版
复制代码

• 点击滴滴个人版按钮

本地安装了滴滴个人版，则打开应用。

• 点击openAppB按钮

与打开滴滴个人版效果一致
