Question

I have a variable called “sellPhone”. I want to add it into the URLWithString. What is proper code to do so?

- (IBAction)buttonCall:(id)sender {

NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *sellPhone = [defaults objectForKey:@"sellPhone"];

[[UIApplication sharedApplication]
 openURL:[NSURL URLWithString:@"tel:%",sellPhone]]; //something like this!!!

What is correct way? Thank you!!!

Answer 1

[NSURL URLWithString:[NSString stringWithFormat:@”tel:%@”,sellPhone]]

To return back to app after call ended:
UIWebView *callWebview = [[UIWebView alloc] init];
NSURL *telURL = [NSURL URLWithString:[NSString stringWithFormat:@”tel:%@”,sellPhone];
[callWebview loadRequest:[NSURLRequest requestWithURL:telURL]];
