应用间跳转

// 1.获取到对应应用程序的URL

NSURL *wechatURL = [NSURL URLWithString:urlString];

// 2.判断手机中是否安装了对应的应用程序

if ([[UIApplication sharedApplication] canOpenURL:wechatURL]) {

// 3.打开应用程序

[[UIApplication sharedApplication] openURL:wechatURL];

}

// 被打开app会调用一下方法

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary*)options； (iOS9.0 更新)

// 1. 获取来源url

NSString *sourceUrl = url.absoluteString;

// 2.1 获取主页控制器

UINavigationController *rootNav = (UINavigationController *)self.window.rootViewController;

// 2.2 把所有的控制器从栈里抛出，返回到主界面

[rootNav popToRootViewControllerAnimated:YES];

// 2.3 将来源URL传给主界面控制器

ViewController *rootVC = [rootNav.childViewControllers firstObject];

rootVC.url = sourceUrl;

// 3. 判断跳转到朋友圈还是微信好友列表;

if ([sourceUrl containsString:@"timeline"])

{

[rootVC performSegueWithIdentifier:@"homeToTimeline" sender:nil];

}else if ([sourceUrl containsString:@"session"]){

[rootVC performSegueWithIdentifier:@"homeToSession" sender:nil];

}

// 在主界面控制器中传递url

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender

{

if ([segue.identifier isEqualToString:@"homeToTimeline"]) {

TimelineViewController *timeVC = segue.destinationViewController;

timeVC.url = self.url;

}

}

// 在目标控制器上调用url

NSString *destinationURL = [[self.url componentsSeparatedByString:@"?"] lastObject];

NSLog(@"%@",self.url);

NSString *urlString = [destinationURL stringByAppendingString:@"://"];

NSURL *url = [NSURL URLWithString:urlString];

// 判断能否跳转

if ([[UIApplication sharedApplication] canOpenURL:url]) {

NSLog(@"%@",url);

[[UIApplication sharedApplication] openURL:url options:nil completionHandler:nil];
