Not all objects support copy.Only classes that comply with the NSCopying protocol can send copy messages.Only classes that comply with the NSMutableCopying protocol can send mutableCopy messages.If a copy or mutableCopy message is sent without

I wrote a few notes about the blind spots in my C language. I only thought that I had experienced and had errors. 1. typedef is used to define a function pointer type method and a new function pointer type. : It is easy to create a type alias. In

The principle of implementing polymorphism in C language: What is a function pointer? Answer: C Programming Language. You can refer to it. In principle, it is a memory address that jumps over and executes the corresponding code segment. In this case,

Printf () is a formatting output function, which is generally used to output information to the standard output device in the specified format. This function is often used in programming. The call format of the printf () function is: Printf ("", );

Summary of intermediate C language knowledge points: 1. sizeof keywords: Determined during compilation, sizeof (object), sizeof (type), sizeof object, sizeof (pointer) = 4. Int a [5]; sizeof (a) = 20; sizeof (& a) = 20; 2. Empty struct cannot be

In the OC syntax, the Copy syntax (Copy + MutableCopy) is provided for copying objects. Among them, it is easy to confuse the shortest copy and the deep copy. The so-calledA shortest copy is an address copy.Does not generate a new object, but adds 1

In the Foundation framework, the NNString class is provided to process string objects. In C, strings are represented in a pair of quotation marks. OC is an extension of C language. In other words, the OC language is built on the basis of C language (

I. Basic concepts of a setThe NSSet class is provided in the Foundation framework. It is a set of Single-value objects and the elements in the NSSet instance are unordered. Only one object can be saved,It is also divided into variable and immutable

For example, how does one change the main function int main (void) in the C program to static int main (void? For example, copy the Code # include int main (void) {printf ("Hi \ n"); return 0;} copy the code to: copy the Code # include static int
