在代码中调用随机整数变量（objective-c、xcode）
我正在尝试编写一些代码，其中计算机会创建 1 到 12 之间的随机整数，并且我希望能够在代码中的其他位置比较该数字。如何在方法中调用该号码？我对此很陌生，所以感谢您的帮助，
这里是我如何在 .h 中调用它的
int losingVault
.m 这是我如何创建随机数
losingVault=rand()%12+2;
如何在代码中的其他地方调用它？
Im trying to write some code where the computer creates a random integer between 1 and 12 and I want to be able to compare that number elsewhere in my code. How do I call that number in a method? Im very new to this so any help is appreciated
heres how i called it in the .h
int losingVault
in the .m this how i create the random number
losingVault=rand()%12+2;
how do i call that elsewhere in my code?

好吧，这没什么可继续的。看来您可能需要一些基本的帮助来理解 Objective-C。人们喜欢推荐几本书，Programming in Objective-C，作者：斯蒂芬·科尚（Stephen Kochan）可能是最受欢迎的。
因此，按照示例代码的编写方式，
losingVault可能会在定义它的整个类中具有可见性。如果您查看 .h 文件，int LosingVault;可能位于@interface {ClassName}块内。在您的 .m 文件中，应该有一个匹配的@implementation {ClassName}块。该块内的任何位置都应该能够通过调用losingVault来访问该变量。您可以通过多种方式使该变量在该类之外可见。我希望这有帮助。
Well, this isn't a lot to go on. It seems like you may need some basic help understanding Objective-C. There are a couple books people like to recommend, Programming in Objective-C by Stephen Kochan is probably the most popular.
So, the way your example code is written,
losingVaultwill probably have visibility in the entire class in which it was defined. If you look in your .h file,int losingVault;is probably within an@interface {ClassName}block. In your .m file, there should be a matching@implementation {ClassName}block. Anywhere inside that block should be able to access the variable by just callinglosingVault. You could make that variable visible outside of that class in a number of ways.I hope this helps.
