As there is no proper documentation on how it works, it is hard to pinpoint the cause of it. Let me advance a theory. Opening an app from browser causes a context switch; indeed from browser to App Store. So for the very first time it’d cost some time, while in subsequent times it will … Read more
I noticed the same problem when calling -[UIApplication openUrl:] from the Application Delegate didReceiveRemoteNotification: or didFinishLaunchingWithOptions: since iOS 7. I solved it by delaying the call a bit using GCD : // objc dispatch_async(dispatch_get_main_queue(), ^{ [[UIApplication sharedApplication] openURL:url]; }); It let iOS some time to finish application initialization and the call is then performed without … Read more
I am pretty sure you want: UIApplication.sharedApplication().openURL(NSURL(string: “tel://9809088798”)!) (note that in your question text, you put tel//:, not tel://). NSURL’s string init expects a well-formed URL. It will not turn a bunch of numbers into a telephone number. You sometimes see phone-number detection in UIWebView, but that’s being done at a higher level than NSURL. … Read more
Swift 3+: func open(scheme: String) { if let url = URL(string: scheme) { if #available(iOS 10, *) { UIApplication.shared.open(url, options: [:], completionHandler: { (success) in print(“Open \(scheme): \(success)”) }) } else { let success = UIApplication.shared.openURL(url) print(“Open \(scheme): \(success)”) } } } Usage: open(scheme: “tweetbot://timeline”) Source
Using a URL According to Apples article Handling Subscriptions Billing and WWDC 2018 Session 705 the following url can be used to link to the manage subscription page: https://apps.apple.com/account/subscriptions Using StoreKit/SwiftUI (iOS 15+) UIKit: Use StoreKits showManageSubscriptions(in:) (Documentation). SwiftUI: Use SwiftUIs modifier manageSubscriptionsSheet(isPresented:) (Documentation).
These steps can be followed on the device. Founded at this link. Run the app from Xcode to install it on your device and then stop it from Xcode. Force quit the app from the app switcher UI on the device. Navigate to the scheme for the project in Xcode. Under the Run section’s Info … Read more
Swift 3 or later import Cocoa let url = URL(string: “https://www.google.com”)! if NSWorkspace.shared.open(url) { print(“default browser was successfully opened”) }
As Kevin points out, URL Schemes are the only way to communicate between apps. So, no, it’s not possible to launch arbitrary apps. But it is possible to launch any app that registers a URL Scheme, whether it’s Apple’s, yours, or another developer’s. The docs are here: Defining a Custom URL Scheme for Your App … Read more
