Why Splash Screen takes long time to launch [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 11 years ago.

In my apps why Splash screen takes long time for launching. Any one tell me please.

Thanks in Advance :) .h file code is:
