ios - 将字典追加到 Swift 数组

Question

我有这段 Swift 代码，我试图将字典附加到数组中。

        var savedFiles: [Dictionary<String, AnyObject>] = []
        var newEntry =  Dictionary<String,AnyObject>()

        if let audio = receivedAudio?.filePathURL {
            newEntry["url"] = audio
        }
        newEntry["name"] = caption

        savedFiles.append(newEntry! as Dictionary<String,AnyObject>)

这给了我最后一行错误(附加)Cannot invoke 'append' with an argument list of type '(Dictionary<String, AnyObject>)'

有什么想法吗？我也尝试过移除强制展开。

Answer 1

请试试这个:

var savedFiles: [[String: AnyObject]] = []
var newEntry: [String: AnyObject] = [:]

if let audio = receivedAudio?.filePathURL {
    newEntry["url"] = audio
}
newEntry["name"] = caption

savedFiles.append(newEntry)
