Question

由于iOS 5.1上的Xcode 4.3在设备上启动/安装应用程序时调试非常慢，我使用的启动模拟器要快得多。（请参阅此问题https://stackoverflow.com/questions/11541288/xcode-4-3-with-ios5-1-pauses-about-10secs-when-debug-starts-simulator-starts-i）

所以我需要做的就是这样：

MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
picker.messageComposeDelegate = delegate;
NSString *s = @"1234567";
picker.recipients =[NSArray arrayWithObject: s];   
picker.body =smsTxt;
if (simulationMode) {
    MessageComposeResult result = MessageComposeResultSent;            <-----------
    [delegate messageComposeViewController:picker didFinishWithResult: result];
} else
    [delegate presentModalViewController:picker animated:YES];

现在的问题是，在iOS-Simulator上执行时，MFMessageComposeViewController无法实例化，并且总是产生nil。

有没有办法在iOS模拟器上创建另一个对象MyOwnMFMessageComposeViewController，它与MFMessageComposeViewController兼容，可以像MFMessageComposeViewController一样传递？

这样的事情：

    MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
    picker.messageComposeDelegate = delegate;
    NSString *s = @"1234567";
    picker.recipients =[NSArray arrayWithObject: s];   
    picker.body =smsTxt;
    if (simulationMode) {
        MyOwnMFMessageComposeViewController *mypicker = [[MFMessageComposeViewController alloc] init];
        mypicker.messageComposeDelegate = delegate;
        NSString *s = @"1234567";
        mypicker.recipients =[NSArray arrayWithObject: s];   
        mypicker.body =smsTxt;
        MessageComposeResult result = MessageComposeResultSent;   
        picker = (MFMessageComposeViewController) mypicker;          
        [delegate messageComposeViewController:picker didFinishWithResult: result];
    } else
        [delegate presentModalViewController:picker animated:YES];

您正在寻找的内容称为“模拟对象”，通常用于测试驱动开发。基本上你要做的是创建MFMessageComposeViewController的子类。这个子类与mfmessagecomposeviewcontroller完全相同，除了你还创建实例变量以显示发生的事情。

所以例如当你的委托调用messageComposeViewController：didFinishWithResult时。模拟对象可能存储结果以及该方法已被触发的标志。请注意，这实际上不会发送任何内容，而只是告诉您已触发的委托和实际对象将起作用。
