Activity indicator not hiding when webpage is loaded.

Activity indicator not hiding when webpage is loaded.

The activity indicator isn't hiding when the web page has finished
loading. Here is my
.h file
@interface PropertyViewController : UIViewController{
IBOutlet UIWebView *propertyNexusHome;
IBOutlet UIActivityIndicatorView *wheel;
NSTimer *timer;
}
.m file
- (void)viewDidLoad
{
[super viewDidLoad];
[property loadRequest:[NSURLRequest requestWithURL:
[NSURL URLWithString:@"http://www.google.com"]]];
[property addSubview:wheel];
timer = [NSTimer scheduledTimerWithTimeInterval:(1.0/2.0)
target:self
selector:@selector(loading)
userInfo:nil
repeats:YES];
// Do any additional setup after loading the view, typically from a nib.
}
-(void)loading {
if (!property.loading)
[wheel stopAnimating];
else
[wheel startAnimating];
}
@end
Im not sure why its not disappearing, how ever it does stop spinning when
the page has loaded.
Thanks in advance.
