Webview on Ios goes blank

Question

Hello I’m starting to program for Ios, and I’m not being able to run a webview, always goes blank, see the code :

-(void)viewDidLoad {
    [super viewDidLoad];
    NSString *fullURL = @"http://conecode.com";
    NSURL *url = [NSURL URLWithString:fullURL];
    NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
    [_viewWeb loadRequest:requestObj];
}

But every time I run the emulator, the webview part goes blank, someone knows what can be?

Answer 1

After creating the view in his Storyboard and the archives Viewcontroller, you make a bond between these two, there at Storyboard, select the bar Utilities > Identity inspector and inform the Viewcontroller, which in my example I called MinhaWebViewController:

Go back to the implementation file (.m), and just below the @interface declared the outlet:

@property (nonatomic, weak) IBOutlet UIWebView *webView;

Realize that for now this outlet has no link at all (note the small circle next to without filling):

To make that bond, go to Storyboard, with the key control pressed, drag the yellow icon to your UIWebView and select the previously created property:

Now you can go back in the implementation file (.m) and note that the little circle is now filled:

You can also check when selecting your UIWebView in the Storyboard and in Utilities > Connections inspector. There is a connection inserted for this outlet:

Ready, just do your implementation to load the URL:

NSString *fullURL = @"http://conecode.com";
NSURL *url = [NSURL URLWithString:fullURL];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[_webView loadRequest:requestObj];

If you still want the whole project, I made it available on Drive for the time being.

For a solution on Swift, I recommend using Csafariwebkit

In your file

import CSafariWebKit

And in the Viewcontroller you want to call Webview

let vc = SafariViewController(url: url, barTintColor: nil, tintColor: nil)
vc.presentSafari(fromViewController: self, whenDidFinish: nil)

Use the colors of your app for a better experience.
