Memory leak or some other issues in my iPad application?

I am fa开发者_如何学运维cing problems with my iPad application some times it gets hang-up my application and still I am not able to figure out the issues why it is happening again and again with my application. I have tested application through instrument. Please help me out how can I figure out what is the problem with my application or how to prevent memory related issues.

There are many tools to help find memory leaks in Objective C programs, some integrated nicely on the OS X platform. Look for "instruments", "clang static analyzer", or "Leaks".
