使用Firebase 4.0的GeoFire警告 - 空段传递给＆＃39; @ return＆＃39;命令+其他

Question

我没有任何警告，然后我更新到Firebase 4.0现在我在GeoFire中有两个警告，它们不会消失。

警告

... / Pods / GeoFire / GeoFire / API / GeoFire.h:108:11：空段传递给＆＃39; @ return＆＃39;命令

... / Pods / GeoFire / GeoFire / API / GeoFire.h：108：5：＆＃39; @ return＆＃39;注释中使用的命令附加到返回void的方法

GeoFire代码

- (void)removeKey:(NSString *)key withCompletionBlock:(GFCompletionBlock)block;

/**
 * Gets the current location for a key in GeoFire and calls the callback with the location or nil if there is no
 * location for the key in GeoFire. If an error occurred, the callback will be called with the error and location
 * will be nil.
 *
 * @param key The key to observe the location for
 * @param callback The callback that is called for the current location
 * @return <- WARNINGS GIVEN ON THIS LINE
 */

是否有人有任何关于此的信息或至少如何安全沉默。在试图删除评论时，它表示GeoFire已被锁定以进行编辑。
