NSString*string=@"Hello world"; 这种语法基本上是照搬C语言的,它声明了一个名为string的变量,其类型是NSString*。也就是说此变量为指向NSString的指针。所有OC语言的对象都必须这样声明,因为对象所占内存总是分配再“堆空间”(heap space)中,而绝不会分配在“栈”(stack)上。
3. Since library code is connected at compile time, the final executable has no dependencies on the library at run timei.e. no additional run-time loading costs, it means that you don’t need to carry along a copy of the library that is being used and you have everything under your ...
using namespace_name name;尽量少使用 using 指示 污染命名空间一般说来,使用 using 命令比使用 using 编译命令更安全,这是由于它只导入了制定的名称。如果该名称与局部名称发生冲突,编译器将发出指示。using编译命令导入所有的名称,包括可能并不需要的名称。如果与局部名称发生冲突,则局部名称将覆盖名称空间版本,而...
