swift 学习字典和函数回调_swift使用block回调一个字典dictionry-优快云博客

这段代码展示了在Swift中如何使用@objc函数处理字典数据，并实现回调函数来获取钱包余额信息。通过遍历钱包地址，获取到HPBBalanceModel对象，并将其转换为NSDictionary进行传递。

@objc func quaryAllBalances(quaryBalances: @escaping (NSDictionary) -> Void){
let allAccounts = HPBUserMannager.shared.walletInfos

        var allAddress: [String] = []
        allAccounts?.forEach {
            allAddress.append($0.addressStr.noneNull)
        }

        HPBMainViewModel.getListBalance(accounts: allAddress, success: { (totalCny,totalUsd,results) in
            var balaces: [String: HPBBalanceModel] = [:]
            results.forEach({
               balaces.updateValue($0, forKey: $0.address)
            })
            var dictionary: [String: Any] = [:]
            for item in balaces {
                var dict: [String: String] = [:]
                let model: HPBBalanceModel = item.value
                dict.updateValue(model.address, forKey: "address")
                dict.updateValue(model.cnyTotalValue, forKey: "cnyTotalValue")
                dict.updateValue(model.usdTotalValue, forKey: "usdTotalValue")
                dictionary.updateValue(dict, forKey: item.key)
            }
            quaryBalances(dictionary as NSDictionary)
        }) { (errorMsg) in
        }
