My application contains more than 开发者_开发知识库200 images each with size approx. 15 KB. I want to flip these image one by one. Is there will be any time lag for loading images? Is there any alternate method for doing that?

Anyone please help!

OK.

Is there will be any time lag for loading images?

Maybe. Try it and see. If there is, run your app under Instruments to see what really caused it.

Is there any alternate method for doing that?

You haven't proposed a primary method to be alternate to.

The main thing is that, since this is an iPhone app, you're probably not going to need 200 images loaded at once. Consider the Home screen: Those icons are about as small as is practical, and there are only 20 (24 on the iPad) of them on the screen at one time.

Assuming you want to allow scrolling or paging through the list, you'll probably want to keep a pageful up and a pageful down already loaded and flipped and ready to display, to make scrolling/paging faster. That's still only 60–72 images, and you can do half to two-thirds of them after displaying the visible 20–36.

Moreover, are the images always flipped? If so, then flip them at build time and copy the flipped images into your app, and do no flips at runtime. Then you're just displaying images.
