我现在正在构建一个应用,需要在两个UIView Controllers
和UIWebView
内加载两个不同的网址。虽然,他们需要在同一个班级。那么有什么方法可以简单地检查"如果故事板ID是XXX,那么加载URL_1,否则加载URL_2"?
这是我的代码:
let day_url = NSURL(string: "http://www.url1.com/")
let day_url_request = NSURLRequest(URL: day_url!)
day_webView.loadRequest(day_url_request)
let week_url = NSURL(string: "http://www.url2.com/")
let week_url_request = NSURLRequest(URL: week_url!)
week_webView.loadRequest(week_url_request)
谢谢!

您的每个UIViewController
都有唯一的ID和自定义类。第一个UIViewController
看起来像这样:
class StoryboardID1: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let day_url = NSURL(string: "http://www.url1.com/")
let day_url_request = NSURLRequest(URL: day_url!)
day_webView.loadRequest(day_url_request)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
对于第二个UIViewController
,我们有:
class StoryboardID2: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let week_url = NSURL(string: "http://www.url2.com/")
let week_url_request = NSURLRequest(URL: week_url!)
week_webView.loadRequest(week_url_request)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
另一种方式
首先,声明您的UIViewController
:
let myViewControllerID = self.storyboard?.instantiateViewControllerWithIdentifier("PutIDHere") as UIViewController
然后检查myViewControllerID
是否实际上是用户导航的控制器:
if segue.identifier == "myViewControllerID" {
...
}
答案 1 :(得分:0)
您可以使用restorationIdentifier而不是Storyboard标识符,并从
中进行检查if self.restorationIdentifier == "View1" {
// load URL1
} else {
// Load URL2
}
祝你好运
