I have a webview and I want to open the urls that I can click in that webview in another ViewController for example to change the navigation bar and add a back button.
This is my current code in objective-c:
- (void)viewDidLoad {
[super viewDidLoad];
NSString *fullURL = #"https://www.apple.com/";
NSURL *url = [NSURL URLWithString:fullURL];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
self.webView.delegate = (id)self;
[self.webView loadRequest:requestObj];
UIRefreshControl *refreshControl = [[UIRefreshControl alloc] init];
[refreshControl addTarget:self action:#selector(handleRefresh:) forControlEvents:UIControlEventValueChanged];
refreshControl.tintColor = [UIColor clearColor];
[self.webView.scrollView addSubview:refreshControl];
}
-(void)handleRefresh:(UIRefreshControl *)refresh {
NSString *fullURL = #"https://www.apple.com/";
NSURL *url = [NSURL URLWithString:fullURL];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:requestObj];
[refresh endRefreshing];
}
Any solutions?
Thank you!
from UIWebview delegate you should use "shouldStartLoadWith" and check navigationType for linkClicked:
func webView(_ webView: UIWebView,
shouldStartLoadWith request: URLRequest,
navigationType: UIWebViewNavigationType) -> Bool {
if navigationType == .linkClicked{
if let url = URL(string:"YourURLString") {
if UIApplication.shared.canOpenURL(url){
UIApplication.shared.openURL(url)
return false
}
}
}
return true
}

I have webView and send my cookies to my site for using same session (web store).
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, CGRectGetMaxX(self.view.frame), CGRectGetMaxY(self.view.frame))];
[webView setDelegate:self];
[self.view addSubview:webView];
NSString *sessionId = [[OCRESTAPIClient sharedClient] sessionId];
NSString *value = [#"xid=" stringByAppendingString:sessionId];
NSURL *url = [NSURL URLWithString:#"http://MySite.ru/cart"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setValue:value forHTTPHeaderField:#"Cookie"];
[webView loadRequest:request];
User can walking on my site and i must to know where he is. How can i get web address of loaded page in webView?
Please make your class the delegate of the webview using
webView.delegate = self
Then override the delegate method,
func webView(_ webView: UIWebView, shouldStartLoadWith request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {
print("current url is \(request.mainDocumentURL!.absoluteString)")
return true;
}
This will give the current url going to be loaded
use UIWebView delegate method
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
self.url = webView.request.mainDocumentURL;
}
How can i get the alert in click of submit ?
i am using WebView..
Here is the code
UIWebView *webView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
[webView setDelegate:self];
NSString *urlAddress = #“sssssss”;
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
[self.view addSubview:webView];
Thanks in Advance..
Check this:
- (BOOL)webView: (UIWebView*)webView shouldStartLoadWithRequest: (NSURLRequest*)request navigationType: (UIWebViewNavigationType)navigationType {
NSString *fragment, *scheme;
if (navigationType == UIWebViewNavigationTypeLinkClicked) {
//1
[webView stopLoading];
fragment = [[request URL] fragment];
scheme = [[request URL] scheme];
if ([scheme isEqualToString: #"file"] && [self respondsToSelector: NSSelectorFromString(fragment)]) {
[self performSelector: NSSelectorFromString(fragment)];
return NO;
}
[[UIApplication sharedApplication] openURL: [request URL]];
}
return YES;
}
You need to set delegate to WebView.
Hope this helps.
1 - Add a IBAction to your submit button.
2 - Inside the method that gets called use UIAlertController to create a alert that will be displayed when the button is clicked.
I'm trying to override a url with the following code:
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
NSString *urlString = #"http://www.google.com/";
NSURL *url = [NSURL URLWithString:urlString];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
[_udazzWebView loadRequest:urlRequest];
NSLog(#"log");
}
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest: (NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
NSLog(#"log2");
//use NSURLRequest object request , to manage the request.
NSURL *urL=request.URL;
NSString *urlStr=[urL absoluteString];
NSLog(#"URLL %#",urlStr);
if([urlStr isEqualToString:#"PostPicPopUp"]){
NSLog(#"log3");
}
return YES;
}
Log2 doesn't appear in the console. I'm guessing it has something to do with replacing NSURLRequest in the viewDidLoad, but I don't know how to do it.
It seems to me you are just missing UIWebView delegates init like
- (void)initWebViewWithRect:(CGRect)rect {
self.webView = [[UIWebView alloc] initWithFrame:rect];
self.webView.backgroundColor = [UIColor whiteColor];
self.webView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
self.webView.opaque=NO;
self.webView.userInteractionEnabled=YES;
self.webView.delegate=self;
[self cleanSubViews];
}
You UIWebView should be defined like
#interface MXMBaseWebView()<UIWebViewDelegate, UIScrollViewDelegate, MXMWebViewProgressDelegate> {
CAGradientLayer *shadowLayer;
MXMWebViewProgressView *_progressView;
MXMWebViewProgress *_progressProxy;
UIRefreshControl *_refreshControl;
}
#property(nonatomic, strong) UIWebView *webView;
#end
so you will do calls like
[self.webView loadRequest: [NSURLRequest requestWithURL:url]];
At this point everything should work properly.
I am using UIWebview to show user profile details. Now when trying to upload the image whole Webview reloading and showing back to the same stage before uploading.
UIWebView *ProfileCellWebview = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, cell.layer.frame.size.width, (MainFrame.size.height - 210))];
[ProfileCellWebview setBackgroundColor:[UIColor clearColor]];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:USERPROFILEPUBLIC,self.appDelegate.currentUser.userId]];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[ProfileCellWebview setDelegate:self];
[ProfileCellWebview loadRequest:requestObj];
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];
[cell addSubview:ProfileCellWebview];
Where i am doing wrong
Implement the code to load the url in viewDidLoad. Hope you write the code in viewWillApear or viewDidApper.
I am learing WebView.
when I do something like
NSString *url = #"www.google.com";
[_webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:url]]];
it fails.
But when I type www.google.com (or even google.com) in standard browser, it works fine.
I also noticed that after loading the page, the url text field in standard browser changes the link from www.google.com to https:// www. google.co.in/?gws_rd=ssl
In above code when I set NSString *url = #"https://www.google.co.in/?gws_rd=ssl" it works fine
So how do I implement my WebView view so that if should work like a standard browser it terms of above context
UIWebView always needs http or https when starting request, if you click on links inside the webView it will handle it itself. So here is how to handle it:
- (void)viewDidLoad
{
[super viewDidLoad];
UITextField *addressBar = [[UITextField alloc] init];
[addressBar setDelegate:self];
[self loadRequestFromString:#"www.google.com"];
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[self loadRequestFromString:textField.text];
[textField resignFirstResponder];
return YES;
}
- (void)loadRequestFromString:(NSString *)urlString
{
NSURL *webpageUrl;
if ([urlString hasPrefix:#"http://"] || [urlString hasPrefix:#"https://"]) {
webpageUrl = [NSURL URLWithString:urlString];
} else if ([urlString containsString:#" "] || ![urlString containsString:#"."]) {
webpageUrl = [NSURL URLWithString:[NSString stringWithFormat:#"http://www.google.com/search?q=%#", [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]];
} else {
webpageUrl = [NSURL URLWithString:[NSString stringWithFormat:#"http://%#", urlString]];
}
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:webpageUrl];
[_webView loadRequest:urlRequest];
}
to open any URL in UIWebView you should add url with protocol
eg #"http://www.google.com".
[NSURL URLWithString:#"http://www.google.com"];
then it will work.
