textFieldDidEndEditing触发“时间太晚"； [英] textFieldDidEndEditing firing "too late"

问题描述

我有一个多视图过程，用户正在输入数据，并且在此过程的每一步都将其保存到模型类属性中.

I have a multiview process the user is entering in data and I'm saving it to the model class properties each step along the way.

我使用textFieldDidEndEditing检查输入是否有效，如果有效，则保存输入的数据.

I use textFieldDidEndEditing to check if the input is valid, and if so, saves the entered data.

在该视图上，我有一个continueButtonClicked事件，该事件检查所有验证是否通过，如果通过，则加载下一个视图.我不在这里设置模型的属性，因为我认为不必这样做，因为每个字段一次都保存到模型1字段中.但是，我注意到了一些问题.

On the view I have a continueButtonClicked event that checks to see if all the validations pass and if so loads the next view. I do NOT set the properties of the model here, because I think I shouldn't have to since each field is saved to the model 1 field at a time. However, I noticed some issues.

如果用户在文本框内并单击继续"按钮，则在textFieldDidEndEditing之前将触发continueButtonClicked事件.最终发生的事情是，在textFieldDidEndEditing中进行保存之前，下一个视图已使用旧"模型填充.

If the user is inside of a textbox and clicks the "Continue" button, the continueButtonClicked event fires BEFORE the textFieldDidEndEditing. What ends up happening is that the next view is populated with the "old" model prior to the save happening in textFieldDidEndEditing.

我想念什么?在继续"上设置所有属性是否合适?如果我正在为网络编程，那将是这样做的方式，但对于本机应用程序似乎并不正确.

What am I missing? Is it proper to set all the properties on the Continue? That's how I would do it if I were programming for the web, but it doesn't seem right for a native app.
