抛出'NSException'实例后终止调用

我突然无法理解我的应用程序发生了什么.这个错误一直在崩溃.我创建了更多试用项目的名称Interface并运行了几次,之后我回去运行我的原始项目.它一直在崩溃.任何人都可以帮助我吗？谢谢

Answer 1

我也有同样的问题.

实际上,我已经为文本创建了一个插座连接.我将其命名为"mytext",由于某些原因我后来决定更改名称,我从标题中删除了@property声明.

事实证明,连接已被删除,编译器继续搜索"mytext".

我不得不进入xib文件并切换"连接浏览器".它表明"mytext"仍然存在.

我从那里开始工作,删除了连接.

上面说你的XIB指向一个项目中不存在的类.

在Interface Builder中,检查类设置.应将所有视图和对象设置为标准类或属于项目一部分的自定义类.这可能是拼写错误......
