为UIViewController的子类抑制Xcode不兼容的指针类型

- (void)someMethod:(id)someObject {
    UIViewController *viewController = (__bridge UIViewController *)someObject;
    // 在这里使用viewController对象
}

- (void)someMethod:(id)someObject {
    UIViewController *viewController = (__bridge_transfer UIViewController *)someObject;
    // 在这里使用viewController对象
}

- (void)someMethod:(id)someObject {
    UIViewController *viewController = (__bridge_retained UIViewController *)someObject;
    // 在这里使用viewController对象
}

- (void)someMethod:(id)someObject {
    UIViewController *viewController = (__autoreleasing UIViewController *)someObject;
    // 在这里使用viewController对象
}
