Objective-C UIWebView not loading website

Question

I am trying to get a UIWebView to display google.com for now, but its not loading:

I just get a blank screen

.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

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

@end

.m

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {

    [super viewDidLoad];

    NSURL *targetURL = [NSURL URLWithString:@"http://www.google.com"];
    NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
    [_webView loadRequest:request];

    // Do any additional setup after loading the view, typically from a nib.
}



- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

What I did is the following to create a web view:

Created a new UIViewController scene
Added a UIWebView to it
connected the webview to .h controller
Made my scene the inital scene
Ran the app, nothing was loaded, no errors, just go straight to UIViewController with nothing in it, please help.

I tried adding the following:

[self.view addSubview:self.webView];

That did nothing

did you try [webView loadRequest:request]; , Also you have to consume webview property in your implementation. — apollosoftware.org, Sep 08 '15 at 19:23
it doesnt make sense when tried adding it as subview ,when outlet is already there — Teja Nandamuri, Sep 08 '15 at 19:32

If You're running Web View on iOS > 9.0, probably You haven't added NSAppTransportSecurity key to project *.plist file, so the app can't request any URL.

If You want to allow all of URL request, then following code should be added to project plist file:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

else if You want to allow only specific URL request:

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>allowed.domain.com</key>
        <dict>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
        </dict>
    </dict>
</dict>

Try adding :

- (void)viewDidLoad {

    [super viewDidLoad];

    //Check if the web view is linked correctly from the XIB
    NSLog(@"WebView : %@",_webView);
    _webView.delegate = self;


    NSURL *targetURL = [NSURL URLWithString:@"http://www.google.com"];
    NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
    [_webView loadRequest:request];

    // Do any additional setup after loading the view, typically from a nib.
}

and add this new method in your class (also implement UIWebViewDelegate in te .h)

- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error
{
   //Check if the web view loadRequest is sending an error message
   NSLog(@"Error : %@",error);
}

This is what was in my console: `WebView : >` – user979331 Sep 08 '15 at 19:40
And never print the didFailLoadWithError Log?? – piyuj Sep 08 '15 at 20:00

If you are really using an outlet for webview, then this should work no matter what.

   [self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.google.com"]]];

add Break point , check if NSURLRequest *request is nil , if nil, then do

NSString *urlString = @"http://www.yourWebAddress.com";
NSURL *url = [NSURL URLWithString:[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
[webView loadRequest:urlRequest];

try to encode the url...hope it will works

Would you happen to be building in Xcode 7 and targeting iOS 9?

If so, you're likely running into the new default security requirement for accessing sites via https, as detailed here:

Perhaps the problem is that you call seter (_webView). Try through:

[self.webView loadRequest:request];
