The implementation of dialing and calling in iOS development

The first of these methods

Cons: After dialing the method, the phone will not return to the application when it hangs up, it will stay in the call log interface

Nsurl *url = [Nsurl urlwithstring:@ "tel//185------"];

[UIApplication shareapplication] openurl:url];

The second method (Apple private API) Audit will be problematic

when a call is made, the user will be dialed and returned to the application when the phone is hung up.

Nsurl *url = [Nsurl urlwithstring:@ "telprompt://185------"];

[UIApplication shareapplication] openurl:url];

The third is to use WebView to load the URL, after the broadcast can automatically return to the application

Note: This webView must not be added to the interface, or it will block other interfaces

@property (Nonatomic,strong) UIWebView * WebView;

If(_webview! = nil){

_webview = [UIWebView alloc] Initwithframe:cgrectzero];
}

[_webview loadrequest:[nsurlrequest requestwithurl:[nsurl urlwithstring:@ "tel://185------"];
