这就是我的Firebase数据的样子:
[ {
"adress" : "Högåsstigen 10 332 33 Gislaved",
"helg" : "18:00-02:00",
"latitude" : 57.2985,
"longitude" : 13.54326,
"namn" : "Restaurang Åsen",
"outlet" : 0,
"phone" : "0371-123456",
"star" : 0,
"tag" : "Restaurang",
"vardag" : "10:00-19:30"
}, {
"adress" : "Högåsstigen 12 332 33 Gislaved",
"helg" : "18:00-02:00",
"latitude" : 57.9985,
"longitude" : 13.94326,
"namn" : "Kalles ställe",
"outlet" : 0,
"phone" : "0371-123456",
"star" : 2,
"tag" : "Restaurang",
"vardag" : "10:00-19:30"
}, {
"adress" : "Högåsstigen 15 332 33 Gislaved",
"helg" : "18:00-02:00",
"latitude" : 55.603384,
"longitude" : 13.020619,
"namn" : "Olles Pub",
"outlet" : 0,
"phone" : "0371-123456",
"star" : 1,
"tag" : "Krog",
"vardag" : "10:00-19:30"
} ]
我想从数据库中获取“地址”。
我有问题将我从Firebase获取的数据转换为追加到数组中,以便稍后使用它们。我得到错误“类型'字符串'的值没有成员'生成器'”。
我不知道如何处理我的编码,任何建议?
var adresserArray = [String]()
let ref = Firebase(url: "https://HIDINGMYURL.firebaseio.com/")
ref.observeEventType(.ChildAdded, withBlock: {snapshot in
let adresser = (snapshot.value.objectForKey("adress")) as! String!
for add in adresser{
adresserArray.append(adresser)
}
})
答案 0 :(得分:1)
你试图在这里迭代字符串
let adresser = (snapshot.value.objectForKey("adress")) as! String!
for add in adresser{
adresserArray.append(adresser)
}
尝试用
替换此代码let adresser = (snapshot.value.objectForKey("adress")) as! String
adresserArray.append(adresser)
