适用于iPhone模拟器，但不适用于设备

这里我添加了视图（UIImageViews），这一切都可以在模拟器上运行但不在设备上（iOS 4.1）wtf！？

Here I addsubviews (UIImageViews) it all works on the simulator but not on the device (iOS 4.1) wtf!?

- (void)addChips:(int)value {
UIImage *chipImage;
switch (value) {
    case 5:
        chipImage = [UIImage imageNamed:@"5chip"];
        break;
    case 25:
        chipImage = [UIImage imageNamed:@"25chip"];
        break;
    case 100:
        chipImage = [UIImage imageNamed:@"100chip"];
        break;
    case 500:
        chipImage = [UIImage imageNamed:@"500chip"];
        break;
    default:
        break;
}

int chipCount = [chipsOnBet count];
UIImageView *addChip = [[UIImageView alloc] initWithImage:chipImage];
addChip.opaque = YES;
addChip.frame = CGRectMake((kStackOffset * chipCount) + 131, 268, 57, 57);
[self.view addSubview:addChip];
[chipsOnBet addObject:addChip];
[addChip release];
}
