iOS - 自定义键盘，更新父视图中的文本字段
我正在实现一个自定义键盘，并且需要在触摸该键盘上的按钮时更新原始文本字段。
我尝试按照这个问题的答案： 使用自定义 inputView 将输入返回到 UITextfield 但我觉得不是很清楚。
在 statViewController 中，我定义了我的 textField xValue，并创建了键盘的一个实例：
DCKeyboard *dckXValue = [[DCKeyboard alloc] initWithNibName:@"DCKeyboard" bundle:nil];
答案的下一行使用 self，所以我认为它建议我应该创建 dckXValue 的属性，即statViewController：
dckXValue.objStatViewController = self;
同样，我遵循答案（添加 @class 行，创建对象/属性），但随后在捕获按钮按下的方法中（在 DCKeyboard.m 中），当我到达该行：
objStatViewController.xValue.text = @"Some value";
当我尝试编译时，出现错误“请求非结构或联合中的成员‘xValue’”。
谁能给我任何关于我可能出错的地方的提示？
谢谢！
I am implementing a custom keyboard and need to update the original textField when buttons are touched on that keyboard.
I have tried following the answer to this question:
Return Inputs to UITextfield with custom inputView
but I don't find it very clear.
In statViewController I have defined my textField xValue, and created an instance of my keyboard:
DCKeyboard *dckXValue = [[DCKeyboard alloc] initWithNibName:@"DCKeyboard" bundle:nil];
The next line of the answer uses self, so I take it that it's suggesting that I should create a property of dckXValue that is a statViewController:
dckXValue.objStatViewController = self;
Again, I follow the answer through (add the @class line, create the object/property) but then in my method that catches my button presses (in DCKeyboard.m), when I reach the line:
objStatViewController.xValue.text = @"Some value";
I am getting the error "Request for member 'xValue' in something not a structure or union" when I try to compile.
Can anyone give me any hints on where I might be going wrong?
Thanks!

这是属性问题，文本字段不是属性。尝试在您的实现文件中#import“StatViewController.h”
It's a problem of property the text field is not a property. Try #import "StatViewController.h" in your implementation file
