我尝试创建 CBLModel 对象并将其保存在 couchbase lite 中。文档保存时没有错误，但是从数据库中检索文档时，文档的属性始终为零。

// 模型

class TestModelUser: CBLModel {
    var userName:NSString?
}

// 创建并保存

let userModel:TestModelUser = TestModelUser(newDocumentInDatabase: db)
userModel.userName = "test user name 10"
userModel.setValue(NSStringFromClass(TestModelUser), ofProperty: "type")
let saved = userModel.save(&error)
if saved {
    println("saved")
}else{
    if let err:NSError = error {
        println(err.localizedDescription)
    }
}

// 取回

let dbView:CBLView = db.viewNamed("userView")
dbView.setMapBlock({ (document, emit) -> Void in
    emit(document["_id"], document)
    if let docType = document["type"] as? String {
        if docType == NSStringFromClass(TestModelUser) {
            emit(document["_id"], document)
        }
    }
    }, version: "5")

let queryResult1:CBLQueryEnumerator = db.viewNamed("userView").createQuery().run(&error)
for row:CBLQueryRow in queryResult1.allObjects as [CBLQueryRow] {
    let user:TestModelUser = TestModelUser(forDocument: row.document)
    if let uName = user.userName {
        println(uName)
    }
}

并且 user.userName 始终为零，也许还有另一种保存文档的方法？

解决了。

文档属性应该有 @NSManaged 修饰符：

class UserModel: CBLModel {
    @NSManaged var userName:NSString?
}
