如何在Objective-C头文件中定义数组？

#import<Foundation/Foundation.h>

@interface MyClass : NSObject

@property (nonatomic, strong) NSArray *myArray;

@end

#import "MyClass.h"

@implementation MyClass

- (instancetype)init {
    self = [super init];
    if (self) {
        self.myArray = @[@1, @"two", @{@"key": @"value"}];
    }
    return self;
}

- (void)doSomething {
    NSLog(@"Array count: %lu", (unsigned long)self.myArray.count);
    NSLog(@"First object: %@", self.myArray[0]);
}

@end
