无法设置 UIViewController ios 的属性 [英] Unable to set property of a UIViewController ios

问题描述

我有一个扩展 UIViewController 的视图控制器.

I have a view controller which extends UIViewController.

@interface MyViewController : UIViewController
    @property (weak, nonatomic) IBOutlet UITextView *phoneTxt;
    @property (nonatomic, strong) NSDictionary *data;
@end

但是，当我尝试通过以下方式设置视图控制器的属性时:

However when I try to set the property of the view controller by:

MyViewController *vvc = (MyViewController *)[sb instantiateViewControllerWithIdentifier:@"MyVC"];
vvc.data = data;

我收到以下错误:

'NSInvalidArgumentException', reason: '-[UIViewController setData:]: unrecognized selector sent to instance 

我已经检查过，视图控制器不是 nil 并且我已经在 MyViewController.m 中合成了属性数据

I have checked, the view controller is not nil and I have synthesized the property data in MyViewController.m

@synthesize data = _data;

为什么我会收到此错误?

Why am I getting this error?

推荐答案

我想你可能忘记在你的故事板/xib 中为你的视图控制器(文件的所有者)设置正确的类，所以它可能被实例化为一个原始的 <代码>UIWievController.

I think you probably forgot to set the proper class for your view controller (File's Owner) in your storyboard/xib, so it probably gets instantiated as a raw UIWievController.
