MBProgressHUD indicator does not hide - ios

Question

i am able to show HUD indicator in viewDidLoad successfully but not able hide it in webViewDidFinishLoad method when webview is completely loaded. Please help.
i am using below code::
in .h file
MBProgressHUD *HUD;
in viewDidLoad
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *query = [[NSString alloc] initWithFormat:#"http://localhost/index.php?uid=%#", [[UIDevice currentDevice] uniqueIdentifier]];
NSURL *url = [[NSURL alloc] initWithString:query];
NSString *response = [[NSString alloc] initWithContentsOfURL:url];
if(response)
{
[webView loadRequest:[NSURLRequest requestWithURL:url]];
}
else
{
//NSLog(#"err %#",response);
}
HUD = [[MBProgressHUD showHUDAddedTo:self.view animated:YES] retain];
HUD.delegate = self;
HUD.labelText = #"loading";
}
and in webViewDidFinishLoad
- (void)webViewDidFinishLoad:(UIWebView *)web
{
[HUD hide:TRUE]; //it does not work for me :(
}

Answer 1

i have fixed the error, i moved the code from viewDidLoad to webViewDidStartLoad and everything is working fine this time :)
- (void)webViewDidStartLoad:(UIWebView *)web
{
MBProgressHUD *HUD = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
HUD.labelText = #"loading";
}
- (void)webViewDidFinishLoad:(UIWebView *)web
{
[MBProgressHUD hideHUDForView:self.view animated:YES];
}

Answer 2

try with this one
[HUD hide:YES];
if(HUD!=nil && [HUD retainCount]>0)
{
[HUD removeFromSuperview];
[HUD release];
HUD=nil;
}

You should not call MBProgressHUD from viewDidLoad, try calling it from viewDidAppear and everything should work well.

Answer 4

Try removing it using this class method:
+ (BOOL)hideHUDForView:(UIView *)view animated:(BOOL)animated
.
- (void)webViewDidFinishLoad:(UIWebView *)web
{
[MBProgressHUD hideHUDForView:self.view animated:YES];
}
If you use this method then you should think about rewriting your viewDidLoad this way:
- (void)viewDidLoad
{
[super viewDidLoad];
//...
MBProgressHUD *HUD = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
HUD.labelText = #"loading";
}
