所以我试图改变我所制作的NSMutableArray中的所有布尔值.

我有:

@property (nonatomic, retain) NSMutableArray *isDinosaurTapped;

并合成:

@synthesize isDinosaurTapped;

并设置[EDITED to show isDinosaurTapped]:

NSMutableArray *newDinosaurTaps = [[NSMutableArray alloc] init];
    for( int i = 0; i < [dinoSprites count]; i++ )
    {
        NSNumber *isTapped = [posPlist valueForKeyPath:[NSString stringWithFormat:@"Dinosaurs.Dinosaur_%i.isTapped", i]];
        [newDinosaurTaps addObject:isTapped];
    }
    self.isDinosaurTapped = [newDinosaurTaps copy];


    for( int i = 0; i < [isDinosaurTapped count]; i++ )
    {
        [isDinosaurTapped replaceObjectAtIndex:i withObject:[NSNumber numberWithBool:NO]];
    }

当我构建它的时候很好,但是当我实际构建并运行时,我不断得到一个SIGABRT:' - [__ NSArrayI replaceObjectAtIndex:withObject:]:发送到实例的无法识别的选择器.

我是否错误地设置了NSMutableArray的属性？但根据这个,我的属性应该没问题.

非常感谢任何反馈!:d
