如何在Objective C中返回类的实例？

@interface MyClass : NSObject
@property (nonatomic, strong) NSString *name;
@end

@implementation MyClass
@end

@interface MyClass : NSObject
@property (nonatomic, strong) NSString *name;

- (instancetype)initWithName:(NSString *)name;
@end

@implementation MyClass

- (instancetype)initWithName:(NSString *)name {
    self = [super init];
    if (self) {
        self.name = name;
    }
    return self;
}
@end

MyClass *myInstance = [[MyClass alloc] initWithName:@"John Doe"];
NSLog(@"My instance name: %@", myInstance.name);
