我尝试使用 Swift SDK 在 Firebase 中一次更新 8 个位置。不知何故我设法更新了前两个，但其他六个只写入父节点，并丢失了它的对应路径。下面是我的 Firebase 数据库的数据，它更好地说明了这个问题:

如您所见，子节点 postid01 和 second 已更新，创建了一个新的子节点，但对于其他位置，这不会发生。
这是我的代码。我根据 Firebase 指南执行了以下操作:
let ref = FIRDatabase.database().reference()
var newPost = ref.childByAutoId()
let newKey = newPost.key
let dict = ["districts/did01/schools/schoolid01/posts/fifth/\(newKey)" : "test","districts/did01/schools/schoolid01/posts/third/\(newKey)": "test",
"districts/did01/schools/schoolid01/posts/fourth\(newKey)": "test","districts/did01/schools/schoolid01/posts/postid02\(newKey)": "test",
"districts/did01/schools/schoolid01/posts/sixth\(newKey)": "test","districts/did01/schools/schoolid01/posts/seventh\(newKey)": "test",
"districts/did01/schools/schoolid01/posts/eighth\(newKey)": "test", "districts/did01/schools/schoolid01/posts/ninth\(newKey)": "test", "districts/did01/schools/schoolid01/posts/tenth\(newKey)": "test", "districts/did01/schools/schoolid01/posts/eleventh\(newKey)": "test", "districts/did01/schools/schoolid01/posts/postid04\(newKey)" : "test"]
ref.updateChildValues(dict, withCompletionBlock: {(Error,FIRDatabaseReference) in
if(Error == nil){
print("EXITO :)")
}else{
print("PAILA :(")
}
})
最佳答案
我刚发现错误，很简单，我在字典上弄错了。没有更新的位置是这样写的:
"districts/did01/schools/schoolid01/posts/fourth\(newKey)": "test"
如您所见，最后一部分在 newKey 之前缺少一个“/”。
