iOS send mail, SMS

The first way: OpenURL

    #pragmaMark-Send mail using System mail client-(void) Launchmailapp {nsmutablestring*mailurl =[[[ nsmutablestring alloc]init]autorelease]; //Add RecipientsNsarray *torecipients = [Nsarray arraywithobject:@"[email protected]"]; [Mailurl AppendFormat:@"mailto:%@", [torecipients componentsjoinedbystring:@","]]; //Add ccNsarray *ccrecipients = [Nsarray arraywithobjects:@"[email protected]",@"[email protected]", nil]; [Mailurl AppendFormat:@"? cc=%@", [ccrecipients componentsjoinedbystring:@","]]; //add encryption to sendNsarray *bccrecipients = [Nsarray arraywithobjects:@"[email protected]", nil]; [Mailurl AppendFormat:@"&bcc=%@", [bccrecipients componentsjoinedbystring:@","]]; //Add a Theme[Mailurl appendString:@"&subject=my Email"]; //Add message Content[Mailurl appendString:@"&body=<b>email</b> body!"]; NSString* email =[Mailurl stringbyaddingpercentescapesusingencoding:nsutf8stringencoding];         [[UIApplication Sharedapplication] OpenURL: [Nsurl Urlwithstring:email]]; }  

The second way: Mfmailcomposeviewcontroller

Let the controller comply with the <MFMailComposeViewControllerDelegate> protocol

#pragmaMark-Send messages within the app//Activate mail feature- (void) sendmailinapp{Class mailclass= (Nsclassfromstring (@"Mfmailcomposeviewcontroller")); if(!Mailclass) {[Wsyfunction alertviewwithtitle:@"Tips"Message@"the current system version does not support in-app send mail functionality, and you can use the Mailto method instead"Buttontitle:@"Determine"]; return; }    if(![Mailclass Cansendmail]) {[Wsyfunction alertviewwithtitle:@"Tips"Message@"user does not have a mail account set up"Buttontitle:@"Determine"]; return; } [self displaymailpicker];}//bring up the mail send window- (void) displaymailpicker{Mfmailcomposeviewcontroller*mailpicker =[[Mfmailcomposeviewcontroller alloc] init]; Mailpicker.mailcomposedelegate=Self ; //Set Theme[Mailpicker setsubject: [NSString stringWithFormat:@"%@", Self.booknamearray[choosebook]]; //Add RecipientsNsarray *torecipients = [Nsarray arraywithobject:@""];    [Mailpicker settorecipients:torecipients]; //Add cc//Nsarray *ccrecipients = [Nsarray arraywithobjects:@ "[email protected]", @ "[email protected]", nil];//[Mailpicker setccrecipients:ccrecipients]; //add encryption to send//Nsarray *bccrecipients = [Nsarray arraywithobjects:@ "[email protected]", nil];//[Mailpicker setbccrecipients:bccrecipients]; //    //Add a pictureUIImage *addpic = [UIImage imagenamed:@"Lanch.jpeg"]; NSData*imagedata = Uiimagepngrepresentation (addpic);//PNG//about MimeType:http://www.iana.org/assignments/media-types/index.html[Mailpicker addattachmentdata:imagedata MimeType:@""FileName:@"Lanch.jpeg"]; //to construct a storage path for a string file//get the document directoryNSString *docpath =[Nssearchpathfordirectoriesindomains (NSDocumentDirectory, Nsuserdomainmask, YES) lastobject]; NSString*strpath = [DocPath stringbyappendingpathcomponent:[nsstring stringWithFormat:@"%@.txt", Self.booknamearray[choosebook]]; //constructing a String objectNSString *book_str =@"";  for(inti =0; i < Self.array.count; i++) {Book_str= [Book_str stringbyappendingstring:[nsstring stringWithFormat:@"\n\n%@", Self.array[i]]; }    //the ability to store a string in a file by sending the WriteToFile:atomically:encoding:error: method to a String object[book_str writetofile:strpath atomically:yes encoding:nsutf8stringencoding Error:nil]; NSData*bookdata =[NSData Datawithcontentsoffile:strpath]; //Send txt text attachment[Mailpicker addattachmentdata:bookdata MimeType:@"Text/txt"Filename:[nsstring stringWithFormat:@"%@.txt", Self.booknamearray[choosebook]]; NSString*emailbody =@"<font color= ' red ' >eMail</font> text";    [Mailpicker setmessagebody:emailbody Ishtml:yes]; [Self Presentmodalviewcontroller:mailpicker animated:yes];}#pragmaMark-Implements Mfmailcomposeviewcontrollerdelegate-(void) Mailcomposecontroller: (Mfmailcomposeviewcontroller *) controller didfinishwithresult: (mfmailcomposeresult) result Error: (Nserror *) error{//Close mail Send window[self dismissmodalviewcontrolleranimated:yes]; NSString*msg; Switch(Result) { Casemfmailcomposeresultcancelled:msg=@"you have canceled editing a message";  Break;  Casemfmailcomposeresultsaved:msg=@"you have successfully saved the message";  Break;  Casemfmailcomposeresultsent:msg=@"you click Send, put the message in the queue, not yet sent";  Break;  Casemfmailcomposeresultfailed:msg=@"you tried to save or send a message failed";  Break; default: Msg=@"";  Break; } [wsyfunction Alertviewwithtitle:@""Message:msg Buttontitle:@"Determine"];}

Finally, the direct call method is used:

[Self Sendmailinapp];
