Your problem is this: since you have Automated Reference Counting (ARC) turned on in your project, you cannot call "release" on objects.
您的问题是：由于您在项目中启用了自动引用计数（ARC），因此无法在对象上调用“release”。
And even if you didn't have ARC turned on, that code would not be correct because A), your brackets in "[strokesarray] objectAtIndex:0]" aren't balanced (syntax error) and B) releasing an object stored in an array means your app will crash with an EXEC_BAD_ACCESS error next time you attempt to access that object in the array.
即使您没有打开ARC，该代码也不正确，因为A），“[strokesarray] objectAtIndex：0]中的括号”不平衡（语法错误）和B）释放存储的对象数组意味着下次尝试访问数组中的该对象时，您的应用程序将崩溃并出现EXEC_BAD_ACCESS错误。
