所以我正在从Firebase获取配置数据,并尝试进行操作。
这是我的结构体:
这是我的解析器方法:
这是我的结构体:
```
struct FireBaseConfiguration: Codable {
var updateTime: String = ""
var iOSMinVersionForceUpdate: String = ""
var iOSMinVersionMessageUpdate: String = ""
var iOSMinFirmwareVersion: String = ""
var privacyPolicyUrlFireBase: String = ""
var termOfUseUrlFireBase: String = ""
}
这是我的解析器方法:
func fireBaseConfigVersionMapParser(dataString: String, version: String) -> FireBaseConfiguration? {
var fireBaseConfiguration: FireBaseConfiguration?
let data = dataString.data(using: .utf8)!
do {
if let jsonArray = try JSONSerialization.jsonObject(with: data, options : .allowFragments) as? NSDictionary {
let model = jsonArray.object(forKey: version)
let data = try JSONSerialization.data(withJSONObject: model!, options: .prettyPrinted)
do {
let parsedModel = try JSONDecoder().decode(FireBaseConfiguration.self, from: data)
print("parsedModel is: \(parsedModel)")
fireBaseConfiguration = parsedModel
} catch let error{
print(error)
}
} else {
print("bad json")
}
} catch let error{
print(error)
}
return fireBaseConfiguration
}
以下是vc中的实现:
self.remoteConfig?.fetch(withExpirationDuration: 0, completionHandler: { [unowned self] (status, error) in
if status == .success {
self.remoteConfig?.activateFetched()
guard let configVersionMap = self.remoteConfig?.configValue(forKey: "iOSConfigVersionMap").stringValue else { return }
if let configModel = self.parser.fireBaseConfigVersionMapParser(dataString: configVersionMap, version: self.getCurrentAppVersion()!) {
print(configModel)
print(configModel.iOSMinVersionForceUpdate)
print(configModel.iOSMinVersionMessageUpdate)
var doubleForceUpdate = Double(configModel.iOSMinVersionForceUpdate)
var doubleMessageUpdate = Double(configModel.iOSMinVersionMessageUpdate)
print(doubleForceUpdate)
print(doubleMessageUpdate)
}
} else {
print("Config not fetched")
print("Error: \(error?.localizedDescription ?? "No error available.")")
}
})
因此,这些打印如下:
FireBaseConfiguration(updateTime: "2018年7月13日", iOSMinVersionForceUpdate: "1.0.2", iOSMinVersionMessageUpdate: "1.0.2", iOSMinFirmwareVersion: "1.0.1", privacyPolicyUrlFireBase: "https://www.name.com/corporate/privacy-policy", termOfUseUrlFireBase: "https://www.name.com/corporate/terms-of-use")

有什么想法吗?

数值没有两个小数点。我认为你可能在寻找的是:在Swift中比较两个版本字符串。 - Scriptable
