Objective C - 如何实现自定义回调方法但强制执行特定参数

，并添加案例代码。

objective-c
// 定义回调方法的协议
@protocol CustomDelegate 
- (void)didReceiveCallbackWithParameter:(NSString *)parameter;
@end
// 实现回调方法的类
@interface CustomClass : NSObject
@property (nonatomic, weak) id delegate;
- (void)performCallback;
@end
@implementation CustomClass
- (void)performCallback {
    // 执行回调方法
    NSString *parameter = @"Hello World!";
    [self.delegate didReceiveCallbackWithParameter:parameter];
}
@end
// 使用回调方法的类
@interface OtherClass : NSObject 
@end
@implementation OtherClass
- (void)didReceiveCallbackWithParameter:(NSString *)parameter {
    NSLog(@"Received callback with parameter: %@", parameter);
}
@end
// 在主函数中测试
int main(int argc, const char * argv[]) {
    @autoreleasepool {
        CustomClass *customObj = [[CustomClass alloc] init];
        OtherClass *otherObj = [[OtherClass alloc] init];
        
        customObj.delegate = otherObj;
        [customObj performCallback];
    }
    return 0;
}
