我的应用程序本质上是一个卡片集合,每个卡片上都有各种消息/信息。人们通过这些卡片,通常向右滑动。我目前得到这个SIG ABRT错误:SIGABRT /无法识别的选择器
#import <UIKit/UIKit.h>
#import "AppDelegate.h"
int main(int argc, char * argv[]) {
@autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}
}
它还版画,这一点:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[filterPageViewController askForPushNotifications]: unrecognized selector sent to instance 0x7f8b6d0acd80'

经过一番调查,我发现有问题的代码。这是我cardSwipedRight方法中的一条线,是我draggableviewbackground类(该类用作甲板,以容纳所有的卡):
[((settingsTableViewController *)([obj.superNavController.viewControllers[obj.profileNum] viewControllers][0])) askForPushNotifications];
这行代码是检查这是否一个if语句中是“注册通知卡”。我感到困惑的是,为什么xcode与askForPushNotifications相关联的filterPageView。 filterPageView不仅没有askForPushNotifications方法,而且我也不会在filterPageView上滑动,也不会在应用程序崩溃时查看它。
您的filterPageViewController是否有一个名为askForPushNotifications的方法? –
不是它不 – Matt
发现这样的错误。你在不应该的地方称呼它。 –
