主要是设置info.plist下的URL Schemes

我们开发的过程中遇到这样一个需求,如果手机下了app,就打开并且跳转到指定页面,否则跳转到app store.
首先在info.plist下的URL Schemes下 新增一个Schemes

然后在浏览器下 打开链接

todolist://

在iOS8下 因该是可以直接打开app的,在iOS9下会询问是否打开某某app
如果需要传参数,就在后面传参数

todolist://?action=inGroup&para0=g123456&para1=u123456

在AppDelegate里
iOS8

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{
    NSLog(@"openURL : %@", url);
    NSLog(@"sourceApplication : %@", sourceApplication);
    // 在这里我是自己解析的参数 据说可以用[]url query]取得参数 我没试过
    NSString *strUrl = [NSString stringWithFormat:@"%@", url];
    NSString *queryStr = [[strUrl componentsSeparatedByString:@"://?"] lastObject];
    NSArray *queryParameters = [queryStr componentsSeparatedByString:@"&"];
    NSMutableDictionary *paramDict = [NSMutableDictionary dictionary];
    for (NSString *strCondition in queryParameters) {
        NSArray *keyValueArr = [strCondition componentsSeparatedByString:@"="];
        [paramDict setObject:[keyValueArr lastObject] forKey:[keyValueArr firstObject]];
    }
    
    NSLog(@"paramDict : %@", paramDict);
    // 跳转到指定页面并且传para0
    ZNTabBarController *zntabBar = (ZNTabBarController *)self.window.rootViewController;
    UINavigationController * nav  = (UINavigationController *)zntabBar.selectedViewController;
    CircleMainController *circleMain = [[CircleMainController alloc] init];
    circleMain.groupsId = [paramDict objectForKey:@"para0"];
    circleMain.hidesBottomBarWhenPushed = YES;
    [nav pushViewController:circleMain animated:YES];

    return YES;
}

iOS9

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {
    NSLog(@"%@", options);
    NSString *strUrl = [NSString stringWithFormat:@"%@", url];
    NSString *queryStr = [[strUrl componentsSeparatedByString:@"://?"] lastObject];
    NSArray *queryParameters = [queryStr componentsSeparatedByString:@"&"];
    NSMutableDictionary *paramDict = [NSMutableDictionary dictionary];
    for (NSString *strCondition in queryParameters) {
    NSArray *keyValueArr = [strCondition componentsSeparatedByString:@"="];
    [paramDict setObject:[keyValueArr lastObject] forKey:[keyValueArr firstObject]];
    }
    NSLog(@"paramDict : %@", paramDict);
    // 跳转到指定页面
    ZNTabBarController *zntabBar = (ZNTabBarController *)self.window.rootViewController;
    UINavigationController * nav  = (UINavigationController *)zntabBar.selectedViewController;
    CircleMainController *circleMain = [[CircleMainController alloc] init];
    circleMain.groupsId = [paramDict objectForKey:@"para0"];
    circleMain.hidesBottomBarWhenPushed = YES;
    [nav pushViewController:circleMain animated:YES];

    return YES;
    
}

再说下app间的跳转

NSURL *url = [NSURL URLWithString:@"todolist://com.hello/?a=1&b=2&c=333"];
    if ([[UIApplication sharedApplication] canOpenURL:url]) {
        [[UIApplication sharedApplication] openURL:url];
    } else {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"message" message:@"地址有误" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
        [alertView show];
    }

如果可以打开,就打开app 否则alert

但是目前有个问题一直没解决
