UIWebView Not Loading View - ios

Question

My UIWebView doesn't seem to be loading:
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *urlAddress = [defaults stringForKey:#"webPage"];
NSLog(#"%#", urlAddress);
NSURLRequest *requestObj = [NSURLRequest requestWithURL:[NSURL URLWithString:urlAddress]];
webView.delegate = self;
[webView loadRequest:requestObj];
}
It is in a UIViewController (connected through IB) and urlAddress returns google.com

Answer 1

Can you check if the URL being fetched is valid?
NSString *urlAddress = [defaults stringForKey:#"webPage"];
NSLog(#"%#", urlAddress);
NSURL *u = [NSURL URLWithString:urlAddress];
if(u){
NSURLRequest *requestObj = [NSURLRequest requestWithURL:u];
webView.delegate = self;
[webView loadRequest:requestObj];
}else{
[[[UIAlertView alloc] initWithTitle:#"" message:#"invalid url." delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil] show];
}
google.com is not a valid url, it should be http://www.google.com. So maybe that is the issue here.

Try this code:
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
webView.delegate = self;
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *urlAddress = [defaults stringForKey:#"webPage"];
NSLog(#"%#", urlAddress);
[self openURLFromString:urlAddress];
}
- (void) openURLFromString:(NSString*) urlString
{
NSURL *url = [self validateAddress:urlString];
NSMutableURLRequest* request = [[NSMutableURLRequest alloc] initWithURL:url];
[webView loadRequest:request];
}
- (NSURL*) validateAddress:(NSString*) address
{
NSURL* result = [NSURL URLWithString:address];
if (!result.scheme)
{
NSString* modifiedURLString = [NSString stringWithFormat:#"http://%#", address];
result = [NSURL URLWithString:modifiedURLString];
}
return result;
}
#pragma mark - UIWebViewDelegate
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSMutableURLRequest *)urlRequest navigationType:(UIWebViewNavigationType)navigationType
{
return YES;
}

Answer 3

You're missing base URL part of the URL ( Click here to read more about this ), which is necessary.
So try this:
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *urlAddress = [defaults stringForKey:#"webPage"];
NSString * theURL = [NSString stringWithFormat:#"http://%#", urlAddress]; // you can also use stringByAppendingString if you prefer
NSLog(#"%#", theURL);
NSURLRequest *requestObj = [NSURLRequest requestWithURL:[NSURL URLWithString:theURL]];
webView.delegate = self;
[webView loadRequest:requestObj];
}
HTH :)
