Info NSURL sharing

[DOMY18]

Ciao a tutti come faccio a inserire un text presente su una label apposto di Hello%2C%20World! ?

label.text = @"Four Is Selected";
NSURL *whatsappURL = [NSURL URLWithString"whatsapp://send?text=Hello%20World!"];
if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
[[UIApplication sharedApplication] openURL: whatsappURL];
