我的代码

-(void)performActionOnEachTrajetWithBlock:(void (^) (Trajet *trajet,NSArray *prevIoUsTrajets))actionBlock{

    NSMutableArray *prevIoUsTrajets = [NSMutableArray arrayWithArray:@[]];
    for (Trajet *trajet in [Trajet MR_findAllSortedBy:@"isActive,date" ascending:YES]){
        actionBlock(trajet,[NSArray arrayWithArray:prevIoUsTrajets]);
        [prevIoUsTrajets addObject:trajet];
    }
    return;
}

错误

*** Terminating app due to uncaught exception 'NSInvalidArgumentException',reason: 'keypath  date not found in entity <NSsqlEntity Trajet id=2>'

感谢你们对我的帮助.

解决方法

[Trajet MR_findAllSortedBy:@"isActive,date" ascending:YES]
     // remove this space ------------^
