我正在寻找一种从OS X
Cocoa应用程序创建HTML格式的电子邮件的方法.
我首选的工作流程是：用户选择一个菜单项,默认的邮件应用程序打开,前台有一个预先填好的新电子邮件.
我可以使用mailto和 – [NSWorkspace openURL]来处理纯文本电子邮件,但这不适用于HTML电子邮件.
解决方法
我也对此感兴趣,所以两天逆向工程Safaris的“本页的邮件内容”功能,我得到了它的工作.
- (void)mailWebArchive:(WebArchive *)webArchive title:(NSString *)aTitle URL:(NSString *)aURL {
NSString *bundleID = @"com.apple.mail";
NSData* targetBundleID = [bundleID dataUsingEncoding:NSUTF8StringEncoding];
NSAppleEventDescriptor *targetDescriptor = nil;
NSAppleEventDescriptor *appleEvent = nil;
targetDescriptor = [NSAppleEventDescriptor descriptorWithDescriptorType:typeApplicationBundleID
data:targetBundleID];
appleEvent = [NSAppleEventDescriptor appleEventWithEventClass:'mail'
eventID:'mlpg'
targetDescriptor:targetDescriptor
returnID:kAutoGenerateReturnID
transactionID:kAnyTransactionID];
[appleEvent setParamDescriptor:[NSAppleEventDescriptor descriptorWithDescriptorType:'tdta'
data:[webArchive data]]
forKeyword:'----'];
[appleEvent setParamDescriptor:[NSAppleEventDescriptor descriptorWithString:aTitle]
forKeyword:'urln'];
[appleEvent setParamDescriptor:[NSAppleEventDescriptor descriptorWithString:aURL]
forKeyword:'url '];
NSAppleEventDescriptor *replyDescriptor = nil;
NSAppleEventDescriptor *errorDescriptor = nil;
AEDesc reply = { typeNull,NULL };
// Send the AppleEvent
OSStatus status = AESendMessage([appleEvent aeDesc],&reply,kAEWaitReply,kAEDefaultTimeout);
if(status == noErr)
{
replyDescriptor = [[[NSAppleEventDescriptor alloc] initWithAEDescNoCopy:&reply] autorelease];
errorDescriptor = [replyDescriptor paramDescriptorForKeyword:keyErrorNumber];
if(errorDescriptor != nil)
status = [errorDescriptor int32Value];
if(status != noErr)
NSLog(@"%s error %d",_cmd,status);
}
}
此代码不检查Mail是否正在运行,因此它仅在Mail已启动时才起作用.
这种方法的专业方面,它适用于实现MailLinkSupported和MailPageSupported的所有电子邮件客户端.见QA1722.
缺点是你不能像mailto一样设置收件人.为此,Scripting Bridge似乎是唯一的解决方案.见修改后的SBSendEmail sample.
