App calls & text messages & Email

In mobile development we will often need to call phone calls, text messaging and email functions, the following is my summary of the method:

1. Call//Method 1 The most commonly used method nsurl *telurl = [Nsurl urlwithstring: "tel://13161906451"]; UIWebView *webview = [[UIWebView alloc] Initwithframe:cgrectzero]; [WebView loadrequest:[nsurlrequest requestwithurl:telurl]];//Method 2 Cons: This method stops after the call ends in the dial-up interface Nsurl *telurl = [Nsurl URLWithString: "tel://13161906451"]; [[UIApplication Sharedapplication] openurl:telurl];//Method 3 before making a call will ask the user whether to dial, hang up the phone will return to the app #warn not be used, audit does not pass, private apinsurl * TELURL2 = [Nsurl urlwithstring: "telprompt://13161906451"]; [[UIApplication sharedapplication] OPENURL:TELURL2];//2. e-mail//method 1//If you want to specify the content of the message, you have to use the MESSAGEUI framework//contains the main header file #import < messageui/messageui.h>//Cannot send mail if (![ Mfmailcomposeviewcontroller Cansendmail]) return;//return to the original program after the message was sent successfully or failed or canceled mfmailcomposeviewcontroller *VC = [[ Mfmailcomposeviewcontroller Alloc] init];//set message subject [VC setsubject:@ "Meeting"];//set message content [VC setmessagebody:@] meeting this afternoon "ishtml : no];//set recipient list [VC settorecipients:@[@ "[email protected]"]];//set cc people list [VC setccrecipients:@[@ "[email  Protected] "]];//set up a BCC list [VC setbccrecipients:@[@"[email protected]"]];//add attachment (one picture) UIImage *image = [UIImage imagenamed:@ "Lufy.jpeg"]; NSData *data = uiimagejpegrepresentation (image, 0.5);//Go to Baidu on search MIMETYPE[VC addattachmentdata:data mimetype:@ "Image/jepg "filename:@" Lufy.jpeg "];//set proxy vc.mailcomposedelegate = self;//display Controller [self presentviewcontroller];//proxy method callback after message sent, will automatically return to the original application-(void) Mailcomposecontroller: (Mfmailcomposeviewcontroller *) controller didfinishwithresult: ( Mfmailcomposeresult) Result Error: (NSERROR *) error{//Close Mail interface [controller Dismissviewcontrolleranimated:yes completio        N:nil];    if (result = = mfmailcomposeresultcancelled) {NSLog (@ "Cancel send");    } else if (result = = Mfmailcomposeresultsent) {NSLog (@ "already issued");    } else {NSLog (@ "send failed"); }}//Method 2 Disadvantage: Does not return application nsurl *emailurl = [Nsurl urlwithstring: "mailto://[email protected]"]; [[UIApplication sharedapplication] OPENURL:EMAILURL];//3. SMS//Method 1//If you want to specify a text message, you have to use the Messageui frame//contains the main header file #import < messageui/messageui.h>//If you can not send a direct return, the simulator can not send text messages, tuneTexting will crash if (![ Mfmessagecomposeviewcontroller Cansendtext]) return;//shows the controller that sent the text message mfmessagecomposeviewcontroller *VC = [[ Mfmessagecomposeviewcontroller alloc] init];//Set SMS content vc.body = @ "Have you eaten yet?" ";///Set the recipient list vc.recipients = @[@" 10010 ", @" 02010010 "];//set up the proxy, this proxy causes the Cancel button to appear in the upper-right corner vc.messagecomposedelegate = self;//display Controller [ Self PRESENTVIEWCONTROLLER:VC animated:yes completion:nil];//proxy method, when the SMS interface is closed when the call, after the end will automatically return to the original application-(void) Messagecomposeviewcontroller: (Mfmessagecomposeviewcontroller *) controller didfinishwithresult: (        Messagecomposeresult) result{//Close SMS interface [controller Dismissviewcontrolleranimated:yes Completion:nil];    if (result = = messagecomposeresultcancelled) {NSLog (@ "Cancel send");    } else if (result = = Messagecomposeresultsent) {NSLog (@ "already issued");    } else {NSLog (@ "send failed"); }}//display controller [self PRESENTVIEWCONTROLLER:VC animated:yes completion:nil];//Method 2 Disadvantage: cannot return to app after send end nsurl *smslurl = [Nsurl URLW Ithstring: "sms://13161906451"]; [[UIApplication sharedapplication] openurl:smslurl];
