openURL
已在 Swift 3 中弃用。
任何人都可以提供一些示例来说明尝试打开网址时替换
openURL:options:completionHandler:
如何工作吗?
您所需要的是:
guard let url = URL(string: "http://www.google.com") else {
return //be safe
}
if #available(iOS 10.0, *) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else {
UIApplication.shared.openURL(url)
}
以上答案是正确的,但如果您想检查自己
canOpenUrl
或不尝试这样。
let url = URL(string: "http://www.facebook.com")!
if UIApplication.shared.canOpenURL(url) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
//If you want handle the completion block than
UIApplication.shared.open(url, options: [:], completionHandler: { (success) in
print("Open url : \(success)")
})
}
注意:如果你不想处理完成也可以这样写。
UIApplication.shared.open(url, options: [:])
无需编写
completionHandler
,因为它包含默认值 nil
,请查看 apple 文档 了解更多详细信息。
如果您想在应用程序本身内部打开而不是离开应用程序,您可以导入 SafariServices 并解决它。
import UIKit
import SafariServices
let url = URL(string: "https://www.google.com")
let vc = SFSafariViewController(url: url!)
present(vc, animated: true, completion: nil)
Swift 3版本
import UIKit
protocol PhoneCalling {
func call(phoneNumber: String)
}
extension PhoneCalling {
func call(phoneNumber: String) {
let cleanNumber = phoneNumber.replacingOccurrences(of: " ", with: "").replacingOccurrences(of: "-", with: "")
guard let number = URL(string: "telprompt://" + cleanNumber) else { return }
UIApplication.shared.open(number, options: [:], completionHandler: nil)
}
}
