Objective C, Thread 1 Program Received Signal SIGABRT
提问by eric.mitchell
I am trying to compile and run a simple tutorial for an Objective C app using Interface Builder. I am using Xcode 4.0.2 and simulating on iOS (iPhone) 4.3
我正在尝试使用 Interface Builder 为 Objective C 应用程序编译和运行一个简单的教程。我正在使用 Xcode 4.0.2 并在 iOS (iPhone) 4.3 上进行模拟
When I build the project, it builds alright but once the app tries to run it crashes with:
当我构建项目时，它构建正常，但是一旦应用程序尝试运行它就会崩溃：
int main(int argc, char *argv[])
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil, @"SimpleUIAppDelegate");
[pool release];
return retVal;
}
I get the error on line 4: int retVal = UI... Thread 1: Program Received Signal "SIGABRT".
我在第 4 行收到错误：int retVal = UI... 线程 1：程序收到信号“SIGABRT”。
If the other files of this project need to be posted for clarity, I can do that.
如果为了清楚起见需要发布该项目的其他文件，我可以这样做。
Thanks!
谢谢！

You have an error in your NIB/XIB file.
您的 NIB/XIB 文件中有错误。
It looks like you have previously attached an IBOutlet (textInput) and now the connection is broken. You should double check all connections in Interface Builder.
看起来您之前附加了一个 IBOutlet (textInput)，现在连接已断开。您应该仔细检查 Interface Builder 中的所有连接。

It's likely that you have set the type of 'File's Owner' incorrectly to UIViewController in your SimpleUIViewController's xib. Please set it to SimpleUIViewController in identity inspector pane.
您可能在 SimpleUIViewController 的 xib 中将“文件所有者”的类型错误地设置为 UIViewController。请在身份检查器窗格中将其设置为 SimpleUIViewController。

Now I see it! Your crash report says:
现在我看到了！你的崩溃报告说：
Unknown class InterfaceBuilderAppDelegate_iPhone
So, it seems that you set your App Delegate in IB to this class, but this class is not available in your project. Check this. Either you misspelled the class name or you should add the relevant class to your project.
所以，看来你在IB中将你的App Delegate设置为这个类，但是你的项目中没有这个类。检查这个。您拼错了类名，或者您应该将相关类添加到您的项目中。
Highly likely, your text field is connected to this app delegate.
很有可能，您的文本字段已连接到此应用程序委托。
Have you connected your text field in Interface Builder to the SimpleUIViewControlleroutlet?
您是否已将 Interface Builder 中的文本字段连接到SimpleUIViewController插座？
Since it seems from the tutorial that you are not using MainWindow.xib, I would say that your project is missing running the proper delegate. Try making this change in your main:
由于从教程中似乎您没有使用 MainWindow.xib，我会说您的项目缺少运行正确的委托。尝试在您的主要内容中进行此更改：
int retVal = UIApplicationMain(argc, argv, nil, @"SimpleUIAppDelegate");
int retVal = UIApplicationMain(argc, argv, nil, @"SimpleUIAppDelegate");
If my hypothesis is right, that should move your forward.
如果我的假设是正确的，那应该会推动你前进。

To fix it, load the XIB in Interface Builder, select the File Inspector tab, and uncheck Use autolayout. Alternatively, you can target iOS 6.0+-only devices and change the minimum target, if you absolutely must have autolayout.
要修复它，请在 Interface Builder 中加载 XIB，选择 File Inspector 选项卡，然后取消选中 Use autolayout。或者，如果您绝对必须使用自动布局，您可以针对仅 iOS 6.0+ 的设备并更改最小目标。
