Nov 22, 2008, 07:00 AM
Hi, i just want to know if some one here can help me to free memory runing my app.

I am working books (app) with more than 45 UIViews jumping with buttons between UIViews.......and every UIView have a background 320x480 png picture.

here show 2 graphics how i am using:



then my 2 questions are:

first, what code i have to put to remove from super view and free more memory removing UIViews

and second: where i have to put that xcode.

some people give me this next code: but i dont know how use it, and where to use it.

myView = [[UIView alloc] init]

or this one:

[UIView imageNamed:@"myImage"]

some idea please ?
thanks a lot brothers.!

You should not have that many UIViews! You can change the image of an UIImageView programatically! You need only have 2 (current, next) or 3 (previous, current, next) views and change the images. That saves a LOT of memory and makes the application MUCH MORE responsive.

[jpg_image1 setHidden:YES];}
