iOS 自定义结构体、结构体转换成对象

1、新建一个头文件，如下代码：

#ifndef Header_h

#define Header_h

struct MyStruce{

    char *name;//(指针形式)

    char *address;

    CGFloat age;

};

typedef struct MyStruce MyStruce;

CG_INLINE MyStruce

MyStruceMake(char *name, char *address, CGFloat age)

{

    MyStruce myStruce;

    myStruce.name = name;

    myStruce.address = address;

    myStruce.age = age;

    return myStruce;

}

#endif /* Header_h */

2、使用

    MyStruce myStruce = {"name","address",12};

    NSString *name = [NSString stringWithFormat:@"%s",myStruce.name];

    NSLog(@"%s   %@",myStruce.name,name);

    

    MyStruce struce = MyStruceMake("name", "address", 123);

   //结构体转换成对象

    NSValue *value = [NSValue valueWithBytes:&struce objCType:@encode(MyStruce)];

    

    NSMutableArray *array = [NSMutableArray array];

    [array addObject:value];

    

    MyStruce struceBack;

    [array[0] getValue:&struceBack];

    NSLog(@"struceBack.name = %s",struceBack.name);

3、另附（NSString与char的转换方法）：

    NSString *string_content = @"sssssss";

    const char *char_content = [string_content cStringUsingEncoding:NSASCIIStringEncoding];

    

    const char *chars = [string_content cStringUsingEncoding:NSASCIIStringEncoding];

    

    NSLog(@"%s",char_content);

    

    string_content = [[NSString alloc] initWithCString:char_content encoding:NSASCIIStringEncoding];

    

    NSString *string =[[NSString alloc] initWithCString:chars encoding:NSASCIIStringEncoding];

    

    NSLog(@"%@",string_content);
