iPhone的方向不正确？ [英] Improper iPhone orientation?

问题描述

我不知道为什么这不工作。我在写一个游戏，涉及滚动行/列的屏幕周围的块。我的方向严格限制在纵向，但它不会这样的行为。

I can't figure out why this isn't working. I'm writing a game that involves scrolling rows/columns of blocks around the screen. I have my orientation limited strictly to Portrait, but it doesn't behave as so.

当我调用下面的方法，它是从平移的速度。使用日志我可以看到，把我的设备颠倒和平移，就好像我的方向支持人像。

When I call the method below, it is handed the velocity from the pan. Using logs I was able to see that holding my device upside-down and panning around acts as if my orientation supports Portrait. How can I -completely- turn off anything but Portrait?

这里有一些代码可以帮助解释我想做什么，并希望证明我的理智。

Here's some code to help explain what I want to do, and to hopefully justify my sanity.

bool horizontalPan = (fabs(velocity.x) >= (fabs(velocity.y)));
    if (horizontalPan)
    {
        if (fabs(velocity.x) > MAX_VELOCITY)
        {
            if (velocity.x > 0)
                velocity = CGPointMake(MAX_VELOCITY, 0);
            else
                velocity = CGPointMake(-MAX_VELOCITY, 0);
        }
        else
        {
            velocity = CGPointMake(velocity.x, 0);
        }
        velocity = ccpMult(velocity, PAN_SENSITIVITY);
        [self panRow:velocity object:object];
    }
    else
    {
        if (fabs(velocity.y) > MAX_VELOCITY)
        {
            if (velocity.y > 0)
                velocity = CGPointMake(0, MAX_VELOCITY);
            else
                velocity = CGPointMake(0, -MAX_VELOCITY);
        }
        else
        {
            velocity = CGPointMake(0, velocity.y);
        }
        velocity = ccpMult(velocity, PAN_SENSITIVITY);
        [self panColumn:velocity object:object];
    }
}

推荐答案

你是否严格限制肖像'

-(BOOL)shouldAutorotate{
    return NO;
}
