iOS开发之打电话，发短信，发送邮件

發(fā)布時(shí)間：2024/5/21 编程问答 30 豆豆

生活随笔收集整理的這篇文章主要介紹了 iOS开发之打电话，发短信，发送邮件小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

iOS開發(fā)中，撥打電話的實(shí)現(xiàn)主要有三種方式：

直接撥號(hào)：撥打完電話之后回不到原來的應(yīng)用，會(huì)停留在通訊錄里面，而且是直接撥打，不彈出提示

- (void)makePhoneCall {NSMutableString *string = [[NSMutableString alloc] initWithFormat:@"tel:%@",@“10086"];[[UIApplication sharedApplication] openURL:[NSURL URLWithString:string]]; }

跳出應(yīng)用打完電話之后回到應(yīng)用

//telprompt協(xié)議屬于蘋果的私有協(xié)議，一旦程序中使用了此協(xié)議，程序無法上架。針對(duì)越獄的機(jī)器開發(fā)的系統(tǒng)，可以使用此協(xié)議。- (void)makePhoneCall {NSMutableString *string = [[NSMutableString alloc] initWithFormat:@“telprompt://%@",@“10086"];[[UIApplication sharedApplication] openURL:[NSURL URLWithString:string]]; }

借助UIWebView打電話

- (void)makePhoneCall {NSMutableString *string = [[NSMutableString alloc] initWithFormat:@"tel:%@",@“10086"];UIWebView *callWebview = [[UIWebView alloc] init];[callWebview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:string]]];[self.view addSubview:callWebview]; }

iOS調(diào)用系統(tǒng)的發(fā)短信功能主要有兩種：

程序外調(diào)用系統(tǒng)發(fā)短信（不能指定短信內(nèi)容，且不能自動(dòng)回到原應(yīng)用）

NSURL *url = [NSURL URLWithString:@"sms://10010"]; [[UIApplication sharedApplication] openURL:url];

程序內(nèi)調(diào)用系統(tǒng)發(fā)短信（發(fā)完短信之后可以回到App）

1.導(dǎo)入MessageUI.framework，并實(shí)現(xiàn)代理方法MFMessageComposeViewControllerDelegate

#import<MessageUI/MessageUI.h>- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result {[self dismissViewControllerAnimated:YES completion:nil];switch(result){caseMessageComposeResultSent://信息傳送成功break;caseMessageComposeResultFailed://信息傳送失敗break;caseMessageComposeResultCancelled://信息被用戶取消傳送break;default:break;} }

2.發(fā)送短信

- (void)showMessageView:(NSArray*)phones title:(NSString*)title body:(NSString*)body {// 判斷用戶設(shè)備能否發(fā)送短信if([MFMessageComposeViewController canSendText]) {MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];//收件人:phones是發(fā)短信的手機(jī)號(hào)碼的數(shù)組，數(shù)組中是一個(gè)即單發(fā),多個(gè)即群發(fā)controller.recipients = phones;//短信內(nèi)容controller.body = body;controller.messageComposeDelegate = self;[self presentViewController:controller animated:YES completion:nil];//修改短信界面標(biāo)題[[[[controllerviewControllers] lastObject] navigationItem] setTitle:title];}else{UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示信息"message:@"該設(shè)備不支持短信功能"delegate:nilcancelButtonTitle:@"確定"otherButtonTitles:nil,nil];[alertshow];} }

3.調(diào)用發(fā)短信的方法

[self showMessageView:[NSArrayarrayWithObjects:@"10086",@"10010",nil] title:@"恭喜" body:@"你們中五百萬大獎(jiǎng)啦！！"];

iOS上可以使用三種方法實(shí)現(xiàn)郵件的發(fā)送：

使用內(nèi)置的MFMailComposeViewController發(fā)送郵件
1、導(dǎo)入MessageUI，實(shí)現(xiàn)MFMailComposeViewControllerDelegate協(xié)議

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error { switch (result) { case MFMailComposeResultCancelled: NSLog(@"Mail send canceled..."); break; case MFMailComposeResultSaved: NSLog(@"Mail saved..."); break; case MFMailComposeResultSent: NSLog(@"Mail sent..."); break; case MFMailComposeResultFailed: NSLog(@"Mail send errored: %@...", [error localizedDescription]); break; default: break; } [self dismissModalViewControllerAnimated:YES]; }

2、檢測設(shè)備是否支持郵件發(fā)送功能

//檢測設(shè)備是否支持郵件發(fā)送功能 Class mailClass = (NSClassFromString(@"MFMailComposeViewController")); if (mailClass != nil) { if ([mailClass canSendMail]) { [self displayComposerSheet];//調(diào)用發(fā)送郵件的方法 } }

3.郵件發(fā)送方法：

- (void)sendE-mail {//創(chuàng)建視圖控制器MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init]; mc.mailComposeDelegate = self; //設(shè)置郵件主題[mc setSubject:@"Hello, World!"];//設(shè)置收件人，收件人有三種：主收件人，cc，bcc[mc setToRecipients:[NSArray arrayWithObjects:@"xxx@126.com", nil];[mc setCcRecipients:[NSArray arrayWithObject:@"xxx@163.com"]]; [mc setBccRecipients:[NSArray arrayWithObject:@"xxx@gmail.com"]]; //設(shè)置郵件主體，有兩種格式：純文本，html格式[mc setMessageBody:@"Watson!!!\n\nCome here, I need you!" isHTML:NO]; [mc setMessageBody:@"<HTML>Hello, Joe! What do you know?</HTML>" isHTML:YES]; //添加附件：需要三個(gè)參數(shù)，一個(gè)是NSData類型的附件，一個(gè)是mime type，一個(gè)附件的名稱NSString *path = [[NSBundle mainBundle] pathForResource:@"blood_orange" ofType:@"png"]; NSData *data = [NSData dataWithContentsOfFile:path]; [mc addAttachmentData:data mimeType:@"image/png" fileName:@"blood_orange"];//視圖呈現(xiàn)[self presentModalViewController:mc animated:YES]; }

通過第三方類庫SKPSMTPMessage發(fā)送郵件
1、下載三方庫，導(dǎo)入類#import “SKPSMTPMessage.h”、#import “NSData+Base64Additions.h”，實(shí)現(xiàn)SKPSMTPMessage代理

//成功 - (void)messageSent:(SKPSMTPMessage *)message {NSLog(@"%@", message); }//失敗 - (void)messageFailed:(SKPSMTPMessage *)message error:(NSError *)error {NSLog(@"message - %@\nerror - %@", message, error); }

2、郵件發(fā)送方法

- (void)sendE-mail {//設(shè)置基本參數(shù)SKPSMTPMessage *mail = [[SKPSMTPMessage alloc] init];[mail setSubject:@"主題"]; // 設(shè)置郵件主題[mail setToEmail:@"xxx@qq.com"]; // 目標(biāo)郵箱[mail setFromEmail:@"xxx@qq.com"]; // 發(fā)送者郵箱[mail setRelayHost:@"smtp.qq.com"]; // 發(fā)送郵件代理服務(wù)器[mail setRequiresAuth:YES];[mail setLogin:@"xxx@qq.com"]; // 發(fā)送者郵箱賬號(hào)[mail setPass:@"填你們自己的"]; // 發(fā)送者郵箱密碼[mail setWantsSecure:YES]; // 需要加密[mail setDelegate:self];//設(shè)置郵件正文內(nèi)容 NSString *content = [NSString stringWithCString:"郵件內(nèi)容" encoding:NSUTF8StringEncoding];NSDictionary *plainPart = @{kSKPSMTPPartContentTypeKey : @"text/plain", kSKPSMTPPartMessageKey : content, kSKPSMTPPartContentTransferEncodingKey : @"8bit"};//添加附件 NSString *vcfPath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"vcf"];NSData *vcfData = [NSData dataWithContentsOfFile:vcfPath];NSDictionary *vcfPart = [NSDictionary dictionaryWithObjectsAndKeys:@"text/directory;\r\n\tx-unix-mode=0644;\r\n\tname=\"test.vcf\"",kSKPSMTPPartContentTypeKey,@"attachment;\r\n\tfilename=\"test.vcf\"",kSKPSMTPPartContentDispositionKey,[vcfData encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];mail.parts = [NSArray arrayWithObjects:plainPart,vcfPart，nil];[mail send]; }

使用openURL發(fā)送郵件（用戶體驗(yàn)較差，程序會(huì)進(jìn)入后臺(tái)，跳轉(zhuǎn)至郵件發(fā)送界面）

- (void)sendE-mail {//創(chuàng)建可變的地址字符串對(duì)象NSMutableString *mailUrl = [[NSMutableString alloc] init];//添加收件人NSArray *ccRecipients = @[@"1229436624@qq.com"]; [mailUrl appendFormat:@"?cc=%@", ccRecipients[0]];//添加密送人NSArray *bccRecipients = @[@"shana_happy@126.com"]; [mailUrl appendFormat:@"&bcc=%@", bccRecipients[0]];//添加郵件主題和郵件內(nèi)容[mailUrl appendString:@"&subject=my email"]; [mailUrl appendString:@"&body=Hello World!"];[[UIApplication sharedApplication] openURL:[NSURL URLWithString:mailUrl]]; }
