我目前在从db中提取所有数据时遇到问题,即1参数为TRUE.

我正在使用NSPredicate,下面是一个示例代码

NSManagedObjectContext *context = managedObjectContext_;

if (!context) {
    // Handle the error.
    NSLog(@"ERROR CONTEXT IS NIL");
}

NSEntityDescription *entity = [NSEntityDescription entityForName:@"tblcontent" inManagedObjectContext:managedObjectContext_];

NSFetchRequest *request = [[NSFetchRequest alloc] init];

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"bookmarked == YES"];

[request setPredicate:predicate];

我尝试将predicatewithformat设置为几乎所有内容,但它仍然没有拉出具有YES值的书签.

我甚至试过(@"bookmarked == %d",YES)但没有运气.我不想得到整个数组,然后通过做if(object.bookmarked == YES)..... blabla 手动过滤它.

我真的很感激一些帮助.

非常感谢.

我在9.3更新中遇到此崩溃,在9.2上一切正常.它能是什么？通过任何来源登录时出现错误(登录通行证,VK,谷歌)
