handleWatchKitExtensionRequest 限制

Question

您在 handleWatchKitExtensionRequest 中可以做什么有限制吗？我尝试从资源包中返回 UIImage，但收到 nil 回复。

这个有效：

-(void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply
{
    reply(@{@"Returning the number 1":@(1)});
}

这失败了：

-(void)application:(UIApplication *)application handleWatchKitExtensionRequest:(NSDictionary *)userInfo reply:(void (^)(NSDictionary *))reply
{
    UIImage *image = [UIImage imageNamed:@"icon-152x152.png"];
    reply(@{@"image":image});
}

您传递的字典必须符合属性列表，这意味着您需要在发送之前将类不是字符串、数字、字典和数组的内容转换为 NSData . How to convert UIImage to NSData.
