Xcode 4和“SIGABRT”错误？ （仅适用于iphone） [英] Xcode 4 and "SIGABRT" error? (only for iphone though)
问题描述
我是ios开发和stackoverflow的新手。我确实尝试在发布之前搜索stackoverflow和google。
我构建了一个简单的小应用程序，最初只留下了一个仅限iphone的应用程序，但决定在结束。我愚蠢地说，当我开始了解xcode 4并将其切换到通用然后再返回时，我正在弄乱，所以我不得不重新复制项目并再次执行。这次我用通用应用程序启动它。 （不是当我创建它但是在我去项目并在那里选择它之后）它创建了ipad文件夹和mainwindow-ipad.xib文件但当然是空的，因为我还没有做任何事情。我把它设置为基于标签的应用程序，所以我的iphone版本也有firstview和secondview nib文件，但ipad版本没有。我首先在iphone版本中设置它，它工作正常。然后我去了ipad版本（我确实消除了mainwindow-ipad的第二个标签，因为我不需要它）
然后我去创建一个新的nib文件并将其与main-ipad.h和main-ipad.m一起放在ipad文件夹中。我复制了我的代码并连接了一切，它在ipad模拟器上运行良好，但现在当我尝试运行iphone模拟器时，我得到SIGABRT错误。我拍了一个屏幕截图。我不完全理解objective-c所以我希望有人可以帮助我吗？我可以发布任何代码或任何你需要的东西来帮助我解决这个错误所以请问。
感谢你的任何帮助和建议！ / p>
谢谢！

再次感谢！如果有人对我的代码有任何建议我会爱他们！就像我说的，我是新手，这是我知道的唯一方法。

发布一些使用
选项2：
尝试在malloc_error_break中设置BreakPoint，以便我们可以获得有关错误的更多信息。
在XCode中转到Run - > Show - > BreakPoints（或者只是cmd + option + B）。然后双击以添加新符号（符号断点）并键入 malloc_error_break 然后按Enter键。
现在运行您的应用并粘贴控制台文字。
检查你的InterfaceBuilder中的连接，你可能用fianllabel错了。
还要检查你的InterfaseBuilder中你的iphone XIB中的自定义类 - >类

转到产品 - >清洁。然后跑。
I'm new to ios development and to stackoverflow. I did try searching both stackoverflow and google before posting.
I built a simple little app, originally just left it an iphone only app, but decided to make it universal in the end. I, stupidly, was messing around when i was getting to know xcode 4 and switched it to universal and then back again so i had to recopy the project and do it again. This time i started it with a universal app. (Not when i created it but after i went to project and selected it there) It created the ipad folder and mainwindow-ipad.xib file but was empty of course since i didn't do anything yet. I had it set up as a tabbed based app so my iphone version had firstview and secondview nib files also, but the ipad version didn't. I set it all up in iphone version first and it worked fine. I then went and laid down the ipad version (i did eliminate the second tab from mainwindow-ipad because i didn't need it)
i then went and created a new nib file and placed it in the ipad folder along with "main-ipad.h" and "main-ipad.m". I copied my code and connected everything and it runs fine on ipad simulator but now when i try and run iphone simulator i get "SIGABRT error. I took a screen shot of it. I don't fully understand objective-c so i was hoping someone can help me? I can post any code or whatever you might need to help me with this error so just ask.
Appreciate any help and suggestions you may have!
Thanks!
[Okay i would have posted image but I can't since I'm a new user, instead i posted the line highlighted and the output from xcode]

Thanks again! If anyone has any suggestions for my code i'd love to here them! Like I said, I'm new to it and thats the only way i know to do this.
------------> If anyone wants, I'll upload the entire project folder. Just ask. Thank you guys for all the help. i'm a n00b with xcode so i haven't got it all down yet.
Post some code where you use finallabel and try to debug your app so you can tell me the line just before the app crashes.
Option 2: Try to set a BreakPoint in malloc_error_break so we can have more info about the error.
In XCode go to Run -> Show -> BreakPoints (or just cmd + option + B). Then double click to add a new symbol (symbolic breakpoint) and type in malloc_error_break then press enter.
Now run your app and paste your console text.
UPDATE If you need help http://developer.apple.com/library/mac/#recipes/xcode_help-breakpoint_navigator/articles/adding_a_symbolic_breakpoint.html
Check your connections inside your InterfaceBuilder, you may have it wrong with fianllabel. Also check your Custom Class -> Class in your iphone XIB in your InterfaseBuilder
UPDATE
Go to Product -> Clean. Then Run.
