Display UIAlertView before opening phone.app
问题 I have a view on map with a button and a label on the button. On the label i have phone number that comes from a plist. The variable of the phone number in the plist called "storePhone" and i implemented it in this way: text4.text = myAnn.storePhone; I made this method for pressing the button and opening the phone.app for dialing the number. Everything works great but i want a UIViewAlert to say to the user something like:"your going to dial this number, are you sure?" before the phone.app is
