ios - Admob banner shown but crashes when tap. Crash only on iPhone, works fine on iPad -

i have universal binary app , start using admob. here code viewcontroller.

the banner shown expected when tap banner, app crashes. strangely, occurs on iphone. no problem ipad.

bannerview_ = [[gadbannerview alloc] initwithadsize:kgadadsizesmartbannerlandscape]; bannerview_.adunitid = @"myid"; cgrect screen_size = [[uiscreen mainscreen] bounds]; bannerview_.frame = cgrectmake(0.0, screen_size.size.width - bannerview_.bounds.size.height, bannerview_.bounds.size.width, bannerview_.bounds.size.height); //2nd line, screen_size.size.width - bannerview_.bounds.size.height works not screen_size.size.height - bannerview_.bounds.size.height bannerview_.rootviewcontroller = self; [self.view addsubview:bannerview_]; [bannerview_ loadrequest:[gadrequest request]];

this log whenever app crahes.
