1.枚举类型
//推荐的定义枚举类型的方式typedef NS_ENUM(NSInteger, RWTLeftMenuTopItemType) { RWTLeftMenuTopItemMain, RWTLeftMenuTopItemShows, RWTLeftMenuTopItemSchedule }; typedef NS_ENUM(NSInteger, RWTGlobalConstants) { RWTPinSizeMin = 1, RWTPinSizeMax = 5, RWTPinCountMin = 100, RWTPinCountMax = 500, }; //不推荐的方式enum GlobalConstants { kMaxPinSize = 5, kMaxPinCount = 500, }; 123456789101112131415161718

//1.定义一个Sample结构体 struct Sample { int a; int b; int c; }; //初始化的时候，可以这样赋值 struct Sample sampleStruct = {1, 2, 1}; NSLog(@"sampleStruct中的值%d",sampleStruct.a ); //2 .定义一个Sample结构体 struct Sample{ int a; int b; int c; }sampleStruct; typedef struct Sample MySampleStruct; //以后用这个结构体，就可以直接用MySampleStruct去定义了 MySampleStruct samDefineStructVarible = {1,2,1}; samDefineStructVarible.a = 1; samDefineStructVarible.b =2; samDefineStructVarible.c = 3;1234567891011121314151617181920212223
