Hi.
some body on itunes, post that my app stop when runing.

my question is, why app some times stop.
is there a Device problem , or app problem managin memory ?

if I use more than 30 UIView, and jumping between them using buttons to show text and png.

how can I clean the memory (the easy way)

I appreciate very much your answers.

Since you're not very experienced your app will contain lots of bugs.
Use XCode's debugger and Instruments and fix all the bugs you find.

thanks...
but if I run instrumens, which i have to run ?
activity monitor ? leaks ?...
please help !
i dont know how to use instruments please !
or if ther is a link to guidme please

thanks a lot !
