Regarding this question I had research lot and got the different suggestion, but non of these 100% works, I have 15 view Controllers and I am releasing all unnecessary objects, variables and dealloc images Data and everything that is unnecessary. My app is not going to crash but got the Received memory warning. Level=1 warning and screens suddenly goes black.

More over I got the below warning after surfing the app for 10-15 minutes if no application is running in back ground. IF More applications are running in background in ipad than i got the error in just 5 mins of surfing the app. 

I had tried the below suggestion From others Answers for this type of questions

1. dealloc and release the objects in `- (void)didReceiveMemoryWarning` Function
2. Change the resolution of MKMapView

Please any one have other solution for this issue than please tell.

Thanx in Advance..!!
