如何在Objective-C中创建泛型属性？

@interface MyClass : NSObject

@property (nonatomic, strong) id genericProperty;

@end

@implementation MyClass

- (void)someMethod {
    if ([self.genericProperty isKindOfClass:[NSString class]]) {
        NSString *stringValue = (NSString *)self.genericProperty;
        // 进行字符串类型的操作
    } else if ([self.genericProperty isKindOfClass:[NSNumber class]]) {
        NSNumber *numberValue = (NSNumber *)self.genericProperty;
        // 进行数字类型的操作
    }
    // 其他类型的处理
}

@end

#define GenericProperty(type, name) \
@property (nonatomic, strong) type name;

#define GenericMethod(type, name) \
- (void)someMethodWith##name:(type)value;

@interface MyClass : NSObject

GenericProperty(NSString *, stringProperty)
GenericProperty(NSNumber *, numberProperty)

@end

@implementation MyClass

GenericMethod(NSString *, String)
{
    // 进行字符串类型的操作
}

GenericMethod(NSNumber *, Number)
{
    // 进行数字类型的操作
}

@end
