uiwebview not loading any content - uiwebview

Question

I am not able to load any webpages.
Any idea why this could be?
The frame for the webview (printed from the debugger)
<UIWebView: 0x8a49840; frame = (0 0; 320 241); autoresize = TM+BM; layer = <CALayer: 0x8a498f0>>
Here is my code:
#import "ViewController.h"
#interface ViewController () <UIWebViewDelegate>
#end
#implementation ViewController
#synthesize webview;
- (void)viewDidLoad
{
[super viewDidLoad];
self.webview.delegate = self;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(void)viewDidAppear:(BOOL)animated
{
}
- (IBAction)buttonPress:(id)sender {
NSLog(#"pressed");
NSURL *theUrl = [NSURL URLWithString:#"www.google.com"];
NSError *e ;
// just for test - ALSO returning nil!!!
NSString *str = [NSString stringWithContentsOfURL:theUrl encoding:NSUTF8StringEncoding error:&e];
NSLog(#"%#",str);
NSURLRequest *theRequest = [NSURLRequest requestWithURL:theUrl];
[self.webview loadRequest:theRequest];
}
- (void)webViewDidStartLoad:(UIWebView *)webView {
NSLog(#"page is loading");
}
// this method is never called
-(void)webViewDidFinishLoad:(UIWebView *)webView {
NSLog(#"finished loading");
}
-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
return YES;
}
#end

Answer 1

use this one it'l work.
problem: in your url http:// was missed
NSURL *theUrl = [NSURL URLWithString:#"http://www.google.com"];

Answer 2

You don't have proper URL.
Because +URLWithString: expects a protocol (e.g. http://, https://),
if you have www.google.com in that case it cannot build a URL.So please try to use like this..
NSURL *url = [NSURL URLWithString:#"http://www.google.com"];

Answer 3

You may also check if your link doesn't contain the "http://" or "https://" and add it.
NSString *website = #"www.google.com";
NSRange textRangeHTTP = [[website lowercaseString] rangeOfString:#"http://"];
NSRange textRangeHTTPS = [[website lowercaseString] rangeOfString:#"https://"];
if((textRangeHTTP.location == NSNotFound) && (textRangeHTTPS.location == NSNotFound))
website = [NSString stringWithFormat:#"http://%#",website];
NSURL *theUrl = [NSURL URLWithString:website];

Answer 4

just use this in your buttoned pressed method
NSURL *theUrl = [NSURL URLWithString:#"http://www.google.com"];
NSURLRequest *theRequest = [NSURLRequest requestWithURL:theUrl];
[self.webview loadRequest:theRequest];
always make sure that using the protocol type that is "http://" is prefixed to the web url string
