生活中每做一件小事儿，聚沙成塔也能成就一件大事儿。
最近一年真的是特别特别忙，但是也在这一块时间做了两件小事儿。
其中一件小事儿就是制作了一下iOS关于邮件发送的相关内容。
大图开张
发个邮件哟-0.png
那么开始吧
使用邮件系统参考有两种方式
=============================================
一种是调用iPhone原生的邮件页面
一种是调用非原生的邮件功能，实现邮件的发送
假如当成一个产品，或者当成一个模块来设计这个发邮件的功能应该分为下面几块内容。
先当做一个简单的app来设计：
发个U件哟.png
为了学习发邮件功能，我们将两种方式都进行编写，下面进行比较

关于UI搭建，根据简洁的原则，我们分为三个模块如下：
发个邮件哟-1@2x.png
非常简单的三个小模块
1-添加收件人邮箱
2-邮件的主题文字
3-增加图片附件
使用MF(也就是原生)发送核心代码如下
/**
使用MF发送邮件
*/
- (void)sendMail {
EasyMailAlertSender *mailSender = [EasyMailAlertSender easyMail:^(MFMailComposeViewController *controller) {
// Setup
[controller setSubject:_mailModel.subjectTitle];
[controller setToRecipients:_mailModel.toRecipients];
[controller setMessageBody:_mailModel.messageText isHTML:NO];
for (NSInteger index = 0; index < _mailModel.sendImages.count; index ++) {
NSString *fileName2 = [NSString stringWithFormat:@"%ld.jpeg",index];
UIImage *image = [_mailModel.sendImages objectAtIndex:index];
NSData *data = UIImageJPEGRepresentation(image, 0.3);
[controller addAttachmentData:data mimeType:@"image/jpeg" fileName:fileName2];
}
NSUserDefaults *sendMailInfo = [NSUserDefaults standardUserDefaults];
SHSendMailModel *model = [SHSendMailModel new];
model.subjectTitle = _mailModel.subjectTitle;
model.toRecipients = _mailModel.toRecipients;
[sendMailInfo setObject:[model mj_JSONString] forKey:SHSendMailKey];
} complete:^(MFMailComposeViewController *controller, MFMailComposeResult result, NSError *error) {
[controller dismissViewControllerAnimated:YES completion:nil];
}];
[mailSender showFromViewController:self competion:^{
UIAlertController *alVc = [UIAlertController alertControllerWithTitle:@"信息提示" message:@"邮件发送成功" preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
}];
[alVc addAction:okAction];
[self presentViewController:alVc animated:YES completion:^{
}];
}];
}
使用非原生核心代码如下
/**
直接发送邮件
*/
- (void)sendMailForMe {
SKPSMTPMessage *myMessage = [[SKPSMTPMessage alloc] init];
myMessage.fromEmail = @"ocsh@qq.com";
myMessage.toEmail = [_mailModel.toRecipients firstObject];
// myMessage.bccEmail = @"ocsh@qq.com";
myMessage.relayHost = @"smtp.qq.com";
myMessage.requiresAuth=YES;
if (myMessage.requiresAuth) {
myMessage.login = @"ocsh@qq.com";
myMessage.pass = @"axbzcseczehtbfha";
}
myMessage.wantsSecure = YES; //为gmail邮箱设置 smtp.gmail.com
myMessage.subject = _mailModel.subjectTitle;
myMessage.delegate = self;
NSString *mailBody = _mailModel.messageText.length>0?_mailModel.messageText:@"";
NSMutableArray *mu = [NSMutableArray array];
//设置邮件内容
NSDictionary *plainPart = [NSDictionary dictionaryWithObjectsAndKeys:@"image/jpeg; charset=UTF-8",kSKPSMTPPartContentTypeKey,mailBody,kSKPSMTPPartMessageKey,@"8bit",kSKPSMTPPartContentTransferEncodingKey,nil];
//添加图片
for (NSInteger index = 0; index < _mailModel.sendImages.count; index ++) {
NSString *fileName2 = [NSString stringWithFormat:@"attachment;\r\n\tfilename=\"%ld.jpeg\"",index];
UIImage *image = [_mailModel.sendImages objectAtIndex:index];
NSData *imgData = UIImageJPEGRepresentation(image, 0.3);
NSDictionary *imagePart = [NSDictionary dictionaryWithObjectsAndKeys:@"image/jpg;\r\n\tx-unix-mode=0644;\r\n\tname=\"test.jpg\"",kSKPSMTPPartContentTypeKey,
fileName2,kSKPSMTPPartContentDispositionKey,[imgData encodeBase64ForData],kSKPSMTPPartMessageKey,@"base64",kSKPSMTPPartContentTransferEncodingKey,nil];
[mu addObject:imagePart];
}
[mu addObject:plainPart];
myMessage.parts = [NSArray arrayWithArray:mu];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
[myMessage send];
});
}
一切内容都以代码为实际依据来进行编写。
