Question

According to Apple\'s documentation, in order to make phone call from my app, I need to implement the following protocols:

1. Behavior does differ between calling -[UIApplication openURL:] with a tel: URL, and clicking a link to the same URL in a UIWebView.

2. Using a UIWebView instead of a UILabel might have some downsides, but you don't have to actually display the UIWebView to get its tel URL handling behavior. Instead, just load a tel URL request in an instance of UIWebView without adding it to your view hierarchy.

For example:

#import 
#import 

@interface PhoneCaller : NSObject
{
  @private
    UIWebView *webview;
}
- (void)callTelURL:(NSURL *)url;
@end

@implementation
- (id)init
{
    self = [super init];
    if (self)
    {
        webview = [[UIWebView alloc] init];
    }
    return self;
}
- (void)callTelURL:(NSURL *)url
{
    [webview loadRequest:[NSURLRequest requestWithURL:url]];
}
- (void)dealloc
{
    [webview release];
    [super dealloc];
}
@end
