仿淘宝分享口令复制打开页面

谁能告诉我淘宝口令咋回事，我自己蒙的解决思路是这样的，你们给评评：

仿淘宝分享口令：

- (void)applicationDidBecomeActive:(UIApplication *)application {

UIPasteboard *pboard = [UIPasteboard generalPasteboard];

NSString *string = pboard.string;

if ([string isEqualToString:@"手机"]) {

//

UIPasteboard *pboard2 = [UIPasteboard generalPasteboard];

pboard2.string = @"";

Html5ViewController *adVC = [[Html5ViewController alloc] init];

adVC.linkUrl = [[NSUserDefaults standardUserDefaults] objectForKey:@"pushInfo"][@"link"];

adVC.title = @"活动详情";

CTBaseNavigationController *nav = self.sCTabBarVC.childViewControllers[0];

[nav pushViewController:adVC animated:YES];

}

}
