按设定的时间间隔创建 UIImageView？
所以我正在为一堂课制作一个简单的基于 UIKit 的 iphone 游戏。如果有人熟悉的话，它与 Sky Burger 类似。如果没有，游戏中的物体将从屏幕顶部掉落，并且屏幕底部的加速计控制的角色将接住它们。
我已经完成了游戏循环和角色移动。我知道如何为 ImageViews 下落设置动画（如果我可以创建它们的话）。我只是不知道如何创建每 1-3 秒左右创建一次的多个 UIImage 视图。
如果有人能给我指出正确的方向，或者对我应该开始寻找的地方有任何建议，我将不胜感激。
另外，如果我不清楚，请告诉我，我会尽力详细说明。
So I'm making a simple UIKit based iphone game for a class. It's similar to Sky Burger if anyone is familiar. If not, the game will be objects falling from the top of the screen and there will be a character that is controlled by the accelerometer at the bottom of the screen that will catch them.
I have the game loop and character movement all done. I know how to animate the ImageViews falling (if i could create them that is). I just cant figure out how to create multiple UIImage views that are created every 1-3 seconds or so.
If anyone could point me in the right direction or has any suggestions of places where I should start looking it would be greatly appreciated.
Also if I'm being unclear just let me know and I'll try to elaborate.

创建一个 NSTimer，每隔 1-3 秒左右安排一次，然后在计时器的操作方法中创建图像视图 (
[[UIImageView alloc] initWithImage:])，定位它们并将它们添加到您的主视图中 (-addSubview:)。不要忘记删除那些不再需要的图像视图，否则您将很快建立太多视图，导致应用程序崩溃。
Create an
NSTimer, schedule it every 1-3 seconds or so, and in the timer's action method, create the image views ([[UIImageView alloc] initWithImage:]), position them and add them to your main view (-addSubview:).Don't forget to remove those image views you no longer need or you'll quickly build up so many views that your app will crash.
