Delete cache of app - ios

Question

I want to delete the cache of my app.
I want to show a web page by using UIWebView.
MY current code:
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var webBrowser: UIWebView!
webBrowser:(UIWebView *)webBrowser shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{
override func viewDidLoad() {
super.viewDidLoad()
let url = NSURL(string:"http://127.0.0.1:8000/admin/accounts/")
let request = NSURLRequest(url:url! as URL)
self.webBrowser.loadRequest(request as URLRequest)
// Do any additional setup after loading the view, typically from a nib.
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
When I added this code
webBrowser:(UIWebView *)webBrowser shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType{
to ViewController,so "Expected declaration" error happen.
What is wrong in my code?
Should I connect my Storyboard and this code in some point?
How can i fix this?

Answer 1

To delete cache try below code
URLCache.shared.removeAllCachedResponses()
URLCache.shared.diskCapacity = 0
URLCache.shared.memoryCapacity = 0
Else you can also change the cache policy of the NSURLRequest
let url = URL(string: "http://127.0.0.1:8000/admin/accounts/")
let request = URLRequest(url: url!,
cachePolicy:NSURLRequest.CachePolicy.reloadIgnoringLocalAndRemoteCacheData,
timeoutInterval: 10.0)
self.webBrowser.loadRequest(day_url_request)
it's Objective C code.Update your code like below
class ViewController: UIViewController,UIWebViewDelegate {
#IBOutlet weak var webBrowser: UIWebView!
override func viewDidLoad() {
super.viewDidLoad()
let url = NSURL(string:"http://127.0.0.1:8000/admin/accounts/")
let request = NSURLRequest(url:url! as URL)
self.webBrowser.delegate = self
self.webBrowser.loadRequest(request as URLRequest)
// Do any additional setup after loading the view, typically from a nib.
}
func webView(_ webView: UIWebView,
shouldStartLoadWith request: URLRequest,
navigationType: UIWebViewNavigationType) -> Bool
// do your stuffs
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

You are using Objective-C code shouldStartLoadWithRequest:
Here is the swift version code to load UIWebView
class ViewController: UIViewController,UIWebViewDelegate {
override func viewDidLoad() {
var webBrowser: UIWebView!
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
webBrowser = UIWebView(frame: UIScreen.main.bounds)
webBrowser.delegate = self
view.addSubview(webBrowser)
if let url = URL(string: "http://127.0.0.1:8000/admin/accounts/") {
let request = URLRequest(url: url)
webBrowser.loadRequest(request)
}
}
}
