ios - SQLite初始化的位置？ (iOS)

Question

我正在为一个开源 iOS 应用程序做贡献，我需要在 SQLite 数据库首次初始化时向其插入行。但是由于我没有任何使用 SQL 的经验，我不知道应该在哪个文件中执行此操作，因此我一直在查看该项目数小时以查找数据传递的位置，但没有成功。这是我要添加行的表。我总共需要 4 行，名称为 avatar_clothes_01(已经存在)、avatar_clothes_02、avatar_clothes_03 和 avatar_clothes_04。提前致谢!

试试这个

Database queue definition

/**
 Database Queue object.
 */
var oDatabaseQueue : FMDatabaseQueue;

Init part

init() {

    let oDirPaths     = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true);
    let sDocsDir      = oDirPaths[0];
    let oDatabasePath = sDocsDir.stringByAppendingPathComponent("databaseName" + ".db");
    self.oDatabase    = FMDatabase(path: oDatabasePath as String);
    self.oDatabaseQueue = FMDatabaseQueue(path: oDatabasePath as String);
}

Inserting in your db, should be better if you pass your model as parameter and adjust the arguments according

func insertTest(id:Int,name:String,points:Int,purchased:Bool){
        self.oDatabaseQueue.inDatabase() { oDatabase in

            if (oDatabase?.open())! {

                var sSql = "INSERT INTO Clothes (";
                sSql = sSql + "ID,";
                sSql = sSql + "Name,";
                sSql = sSql + "Points,";
                sSql = sSql + "Purchased";
                sSql = sSql + ") VALUES (";
                sSql = sSql + "?,";
                sSql = sSql + "?,";
                sSql = sSql + "?,";
                sSql = sSql + "?";
                sSql = sSql + ")";
                Int(purchased)
                let oArguments : [Any] = [
                    id,
                    name,
                    points,
                    Int(purchased)
                ];

                if (database!.executeUpdate(sSql, withArgumentsIn: oArguments)) {

                    database!.commit()
                }
            }
        }
}
