Phone calls iphone system

I know that there are three ways to call the system call can be realized:
1. NSString * callString = [NSString stringWithFormat: @ "tel:% @", number];
[[UIApplication sharedApplication] openURL: [NSURL URLWithString: callString]];
This will pop-up boxes, but after the kick does not automatically return to our application

2. UIWebView * callWebview = [[UIWebView alloc] init];
NSString * callString = [NSString stringWithFormat: @ "tel :/ /% @", number];
NSURL * telURL = [NSURL URLWithString: callString];
[CallWebview loadRequest: [NSURLRequest requestWithURL: telURL]];

3. NSString * callString = [NSString stringWithFormat: @ "telprompt:% @", number];
[[UIApplication sharedApplication] openURL: [NSURL URLWithString: callString]];

But behind these two, they will first pop up a message box out how to put this prompt steps to remove ah, I see the QQ address book is done
