我需要将数据缓存在磁盘上以供脱机查看,我在apollo-ios源中找到了ApolloSQLite,但找不到任何ApolloSQLite文档(我也尝试过Google搜索)。
环境:
Xcode 10.1
macOS 10.14.3
CocoaPods 1.5.3
Apollo (0.9.5)
SQLite.swift (0.11.5)
pod install
之后出现太多错误:
pod 'Apollo'
pod 'Apollo/SQLite'
答案 0 :(得分:0)
当我使用CocoaPods 1.5.3
时,在Apollo/Core
之后缺少源pod install
时,会导致错误。我已经通过将CocoaPods升级到1.6.0修复了它。
顺便说一句,最初的问题是如何使用ApolloSQLite?,因为我没有找到有关ApolloSQLite的任何文档。经过过多的搜索和查询后,我在下面列出了我的步骤,供其他人寻求帮助:
pod 'Apollo' pod 'Apollo/SQLite'
需要一个文件路径来保存用于缓存数据的sqlite文件。粘贴我的代码以供参考:
func temporarySQLiteFileURL() -> URL {
let applicationSupportPath = NSSearchPathForDirectoriesInDomains(.applicationSupportDirectory, .userDomainMask, true).first!
let dbPath = applicationSupportPath + "/com.[special name].cache"
if !FileManager.default.fileExists(atPath: dbPath) {
try? FileManager.default.createDirectory(atPath: dbPath, withIntermediateDirectories: true, attributes: nil)
}
let url = URL(fileURLWithPath: dbPath)
return url.appendingPathComponent("db.sqlite3")
}
配置ApolloClient:
let configuration = URLSessionConfiguration.default
configuration.timeoutIntervalForRequest = 10
let url = URL(string: self.graphQLApiAddress!)!
let networkTransport = HTTPNetworkTransport(url: url, configuration: configuration)
let cache = try? SQLiteNormalizedCache(fileURL: temporarySQLiteFileURL())
let store = ApolloStore(cache: cache ?? InMemoryNormalizedCache())
self.apolloClient = ApolloClient(networkTransport: networkTransport, store: store)
