从当前应用调整到系统自带应用，一行代码搞定

[[UIApplication sharedApplication] openURL:url];
通过给url不同的值，可以实现调用系统自带 电话／短信／邮箱／浏览器

1. 调用 电话phone

   • 拨打电话之后不跳转回app
     [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://800888"]];
   • 拨打电话之后跳转回app
     [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"telprompt://800888"]];

2. 调用自带 浏览器safari
   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.abt.com"]];

3. 调用 自带Mail
   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://admin@abt.com"]];

4. 调用 SMS
   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://800888"]];

5. 调用 app Store
   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms-apps://"]];

6. 调用 iBook
   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms-books://"]];

7. 调用 Map
   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"maps://"]];

8. 调用 Facetime
   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"facetime://"]];

9. 调用 Music
   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"music://"]];

10. 跳转到系统设置相关界面
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=WIFI"]];

设置子界面的跳转关键字
