ios – 黑客入侵MFMessageComposeViewController

MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];

if([MFMessageComposeViewController canSendText]) {
    picker.recipients = [NSArray arrayWithObject:@"1234"];
    picker.body = @"Hello";
    [picker performSelector:@selector(smsComposeControllerSendStarted:) withObject:[UIButton buttonWithType:UIButtonTypeCustom]];
}

结果没有任何结果.甚至在控制台上都没有失败异常.我都没有在短信应用上看到消息.我发送邮件的人也没有得到它.

可以在这里找到iMars和MFMessageComposeViewController方法的列表.

我写了一个快速代码来验证这些是否是MFMessageComposeViewController中实际存在的项目.

uint varCount = 0;
Class cls= [MFMessageComposeViewController class];
Ivar *vars =  class_copyIvarList(cls,&varCount);

for (uint i = 0; i < varCount; i++) {
   Ivar var = vars[i];
   const char* name = ivar_getName(var);
   const char* typeEncoding = ivar_getTypeEncoding(var);
   printf("iVar%i------------> %s\n",i+1,name);
}    
free(vars);

Method *imps = class_copyMethodList(cls,&varCount);
for (uint i = 0; i < varCount; i++) {
    SEL sel = method_getName(imps[i]);        
    printf("Method%i------------> %s\n",[(NsstringFromSelector(sel)) UTF8String]);
}

它产生以下输出：

iVar1------------> _messageComposeDelegate
iVar2------------> _recipients
iVar3------------> _body
iVar4------------> _subject
iVar5------------> _mutableAttachmentURLs
iVar6------------> _currentAttachedVideoCount
iVar7------------> _currentAttachedAudioCount
iVar8------------> _currentAttachedImageCount
iVar9------------> _temporaryAttachmentURLs
iVar10------------> _attachments
Method1------------> disableuserAttachments
Method2------------> setCurrentAttachedVideoCount:
Method3------------> setCurrentAttachedAudioCount:
Method4------------> setCurrentAttachedImageCount:
Method5------------> _MIMETypeForURL:
Method6------------> _isVideoMIMEType:
Method7------------> _isAudioMIMEType:
Method8------------> _isImageMIMEType:
Method9------------> mutableAttachmentURLs
Method10------------> _contentTypeForMIMEType:
Method11------------> _updateAttachmentCountForAttachmentURL:
Method12------------> _buildAttachmentInfoForAttachmentURL:andAlternameFilename:
Method13------------> temporaryAttachmentURLs
Method14------------> canAddAttachmentURL:
Method15------------> addAttachmentData:withAlternateFilename:
Method16------------> _setCanEditRecipients:
Method17------------> messageComposeDelegate
Method18------------> setMutableAttachmentURLs:
Method19------------> currentAttachedVideoCount
Method20------------> currentAttachedAudioCount
Method21------------> currentAttachedImageCount
Method22------------> setTemporaryAttachmentURLs:
Method23------------> dealloc
Method24------------> viewWillAppear:
Method25------------> initWithNibName:bundle:
Method26------------> automaticallyForwardAppearanceAndRotationMethodstochildViewControllers
Method27------------> setModalPresentationStyle:
Method28------------> body
Method29------------> setSubject:
Method30------------> subject
Method31------------> setMessageComposeDelegate:
Method32------------> setBody:
Method33------------> addAttachmentURL:withAlternateFilename:
Method34------------> addAttachmentData:typeIdentifier:filename:
Method35------------> attachmentURLs
Method36------------> attachments
Method37------------> recipients
Method38------------> smsComposeControllerCancelled:
Method39------------> smsComposeControllerSendStarted:
Method40------------> setRecipients:

在我看来,smsComposeControllerSendStarted：方法可能比启动消息发送的实际函数更多的是委托.在上面的方法列表中,没有一个方法签名看起来更接近sendMessage：或类似于实际发送消息的函数.

我的问题是：

1)所有真正的MFMessageComposeViewController都在幕后.或者它是否有一些无法通过运行时函数访问的类集群？

2)如何找出实际的messageSend方法及其实现的类？

任何想法将不胜感激.

谢谢.
