handleWatchKitExtensionRequest限制

Question

handleWatchKitExtensionRequest对您的行为有限制吗？我尝试从资源包中返回UIImage但我收到nil回复。

这有效：

-(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});
}
