I'm looking to hide or disable `UIButton`. I'm using `IBAction` : here is the code in 

.h file 

```
-(IBAction)siteButton:(id)sender;

```

.m file 

```
-(IBAction)siteButton:(id)sender
{

    JSONData = [jsonLoader getJSONData];

    NSString *mySiteString = [NSString stringWithFormat:@"%@", [[JSONData objectAtIndex:0] objectForKey:@"mySiteButton"]];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:mySiteString]];

    NSLog(@"%@",mySiteString);

}

```
