URL:统一资源定位符 tel://110 file:///apple/Desktop/
协议头Scheme:http:// tel:// file://

要想实现应用间的跳转，必须配置协议头
项目->info->url types -> + ->配置协议头
示例：
新闻应用：
@interface ViewController ()/** * 点击之后跳转到微信 */- (IBAction)jump;/** * 点击微信好友按钮跳转到微信 */- (IBAction)sesstion;/** * 点击朋友圈按钮跳转到微信 */- (IBAction)timeline;@end@implementation ViewController// 跳转到主页- (IBAction)jump { [self openWeiXin:@"weixin://"];}// 跳转到好友列表- (IBAction)sesstion { [self openWeiXin:@"weixin://session?news"];}// 跳转到朋友圈- (IBAction)timeline { [self openWeiXin:@"weixin://timeline"];}- (void)openWeiXin:(NSString *)urlStr{ // 1.创建要打开的App的URL NSURL *weixinURL = [NSURL URLWithString:urlStr]; // 2.判断是否该URL可以打开 if ([[UIApplication sharedApplication] canOpenURL:weixinURL]) { // 3.打开URL [[UIApplication sharedApplication] openURL:weixinURL]; }}@end 微信应用：
AppDelegate
@implementation AppDelegate- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. return YES;}/** * 当通过别应用打开该应用的时候会执行该方法 * * @param url 通过哪一个URL跳转过来的 */- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{ // 取出来根控制器 UINavigationController *rootNav = (UINavigationController *)self.window.rootViewController; [rootNav popToRootViewControllerAnimated:NO]; // 取出ViewController ViewController *mainVc = [rootNav.childViewControllers firstObject]; NSString *urlStr = url.absoluteString; if ([urlStr rangeOfString:@"session"].length) { mainVc.appURLStr = urlStr; // 跳转到微信好友界面 [mainVc performSegueWithIdentifier:@"session" sender:nil]; } else if ([urlStr rangeOfString:@"timeline"].length){ // 跳转到朋友圈界面 [mainVc performSegueWithIdentifier:@"timeline" sender:nil]; } return YES;}@end ViewController
