Try this. For example you want to open an Instagram app:
尝试这个。例如你想打开一个 Instagram 应用程序：
var instagramHooks = "instagram://user?username=johndoe"
var instagramUrl = NSURL(string: instagramHooks)
if UIApplication.sharedApplication().canOpenURL(instagramUrl!)
{
UIApplication.sharedApplication().openURL(instagramUrl!)
} else {
//redirect to safari because the user doesn't have Instagram
UIApplication.sharedApplication().openURL(NSURL(string: "http://instagram.com/")!)
}

In SecondApp
在第二个应用程序中
Go to the plist file of SecondApp and you need to add a URL Schemes with a string iOSDevTips(of course you can write another string.it's up to you).
转到SecondApp的plist文件，你需要添加一个带有字符串iOSDevTips的URL Schemes（当然你可以写另一个字符串，这取决于你）。
2 . In FirstApp
2 . 在第一应用
Create a button with the below action:
使用以下操作创建一个按钮：
- (void)buttonPressed:(UIButton *)button
{
NSString *customURL = @"iOSDevTips://";
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:customURL]])
{
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:customURL]];
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"URL error"
message:[NSString stringWithFormat:@"No custom URL defined for %@", customURL]
delegate:self cancelButtonTitle:@"Ok"
otherButtonTitles:nil];
[alert show];
}
}
That's it. Now when you can click the button in the FirstApp it should open the SecondApp.
就是这样。现在，当您可以单击 FirstApp 中的按钮时，它应该会打开 SecondApp。

在 swift4 位智中
class FullMapVC: UIViewController {
var lat:CLLocationDegrees?
var long:CLLocationDegrees?
func wazeMaps()
{
let openUrl = URL(string: "waze://?ll=\(String(describing: lat!)),\(String(describing: long!))&navigate=yes")!
UIApplication.shared.open(openUrl , options:[:]) { (success) in
if !success
{
}
}
}
}
replace url with if you wanna use google maps
如果您想使用谷歌地图，请将 url 替换为
let openUrl = URL(string: "comgooglemaps://?saddr=&daddr=\(String(describing: lat!)),\(String(describing: long!))&directionsmode=driving")!
