Operations depending on generic parameters arenotallowed, which is enforced during well-formedness checking. Allowing generic unevaluated constants would require a way to check if they would always evaluate successfully to prevent errors that are not caught at declaration time. This ability forms part o...

二、Objcet-C 关于xCode内存管理中内存分配和释放的一些经验 即使是高手也难免会有意无意的造成内存泄漏 1.当声明的属性为(retain)时,每一次赋值都会使应用计数+1,所以,在释放时,要小心。 2.当调用的官方框架中的方法为 initXXXXX或者copyXXXXXX时,创建的对象引用计数为1,并且,需要我们调用release 手动释放。
