ios使用openUrl进行应用跳转

1.拨打电话：

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://68979"]]; //直接拨打
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"telprompt://68979"]]; //弹出确订提示

2.调用Safari打开网址:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.baidu.com"]];

3.发送邮件：

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://260548721@qq.com"]];

4.发送短信：

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://68979"]];

5.打开Appstore:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"itms-apps://itunes.apple.com/us/app/id%@", AppID]]];

IOS 8開始支持跳转到应用的设置页：

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];

IOS5.1以后已经不支持例如以下方式的跳转：

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=WIFI"]];
