IOS下使用openUrl下打开不同的系统应用和设置界面

[[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

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://800888"]];

拨打电话时不出现确认框

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"telprompt://800888"]];

拨打电话之时弹出确认框

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://"]]; 注意后面加上faceTime的账号如：99999@qq.com

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"]];
