Question

如果我在iOS模拟器（iPhone 4英寸32位iOS 7.1）中运行我的应用程序，我会收到此错误：

线程1：信号SIGABRT

错误：

int main(int argc, char * argv[])
{
   @autoreleasepool 
   {
       return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
   }
}

我希望有人可以帮助我。

Answer 1

名为ViewController的类中的Filter1不存在。您可能已从代码中删除了插座或某些内容，但忘记从故事板中的实际对象中删除该链接。右键单击链接到Filter1的内容，看看它是否还有旧的（已删除的）连接。

Answer 2

您似乎设置了一个动作为filter1:的按钮，但您从未将filter1:方法添加到ViewController课程。

也许您将方法定义为filter1而不是filter1:。冒号有很大的不同。

如果您的方法确实如此：

- (IBAction)filter1 {
}

然后，您需要更改按钮以使用选择器filter1而不是filter1:。或者将方法更改为：

- (IBAction)filter1:(id)sender {
}

信号SIGABRT错误
