对于复制Foundation中的对象，默认并不是深复制，例如copy NSMutableArray对象是浅复制，只是对其引用进行复制；而copy NSMutableString对象是深复制，对原来引用的对象的具体内容也进行了复制...@property (nonatomic, copy) NSMutableArray *mArray;等同于 - (void)setMArray:(NSMutableArray *)mArray...- { _mArray = mArray.copy; } 你的mArray属性就成了NSArray，NSMutableArray只能用strong修饰，不存在有copy修饰的情况
NSMutableArray *arrM = [NSMutableArray arrayWithArray:@[@1,@2]]; id cp1 = [arrM mutableCopy]

NSArray的容量是固定的，而NSMutableArray的容量是可变的，我们可以在NSMutableArray实例化的时候先初始化一个容量，不过这个容量不是固定的，不够的时候会自动增加...(1) NSMutableArray的初始化 NSMutableArray的便利初始化函数：-(id) initWithCapacity : (NSUInteger)...demo: 1 2 3 4 //NSMutableArray的便利初始化 NSMutableArray *array3 = [[NSMutableArray alloc] initWithCapacity...:3]; //NSMutableArray的便利构造器 NSMutableArray *array4 = [NSMutableArray arrayWithCapacity:3]; ...NSMutableArray *array = [NSMutableArray arrayWithObjects:@"111", @"222", @"333", nil]; //添加元素 [array
