我有19个文本域要上传到firebase数据库。起初我写了这个ref.child("Coupons").child(self.countyyryr.text!).child(self.childx.text!).setValue(["company name" : self.companyname.text, "category" : self.category.text, "email" : self.email.text, "phonenumber" : self.phonenumber.text, "hours" : self.hours.text, "logo" : self.logo.text, "yelplink" : self.yelplink.text, "totaloffer" : self.totaloffer.text, "cp0name" : self.cp0name.text, "cp0code" : self.cp0code.text, "cp0amount" : self.cp0amount.text, "cp0picture" : self.cp0picture.text, "cp1name" : self.cp1name.text, "cp1code" : self.cp1code.text, "cp1amount" : self.cp1amount.text, "cp1picture" : self.cp1picture.text])
和xcode陷入了索引。然后我将上传功能分成两部分：
ref.child("Coupons").child(self.countyyryr.text!).child(self.childx.text!).setValue(["company name" : self.companyname.text, "category" : self.category.text, "email" : self.email.text, "phonenumber" : self.phonenumber.text, "hours" : self.hours.text, "logo" : self.logo.text, "yelplink" : self.yelplink.text, "totaloffer" : self.totaloffer.text])
ref.child("Coupons").child(self.countyyryr.text!).child(self.childx.text!).setValue([""cp0name" : self.cp0name.text, "cp0code" : self.cp0code.text, "cp0amount" : self.cp0amount.text, cp0picture" : self.cp0picture.text, "cp1name" : self.cp1name.text, "cp1code" : self.cp1code.text, "cp1amount" : self.cp1amount.text, "cp1picture" : self.cp1picture.text])
只有第二个功能正在上传。我尝试添加一个延迟来查看互联网连接是否有问题但是，第二个功能仍然是唯一上传的功能。然后我尝试制作3个不同的功能，但现在没有一个上传。以下是我目前的代码，感谢任何帮助。

答案 0 :(得分：0)
两个函数都在执行，但是您通过将值设置为其他值来覆盖路径的值。在设置路径的值后使用b而不是.updateChildValues，或者将更新组合到单个字典中并一次性设置值。
setValue请参阅文档here。
