Ios 在我将UIVIew连接到我的代码后，它崩溃了，为什么？
我按下CONTROL并将AppView.xib中的UIImageVIew和UILabel拖到名为“AppView.h”的代码文件中。在连接运行正常的两个UI小部件之前，我想知道导致崩溃的原因。非常感谢您的回答。 @财产 代码如下：Ios 在我将UIVIew连接到我的代码后，它崩溃了，为什么？,ios,objective-c,uiview,xib,Ios,Objective C,Uiview,Xib,我按下CONTROL并将AppView.xib中的UIImageVIew和UILabel拖到名为“AppView.h”的代码文件中。在连接运行正常的两个UI小部件之前，我想知道导致崩溃的原因。非常感谢您的回答。 @财产 代码如下： #import <UIKit/UIKit.h> @interface AppView : UIView @property (weak, nonatomic) IBOutlet UIImageView *icon; @property (weak, n
