iphone - Rotating a View in iOS causes UIImageView height issues -

i have been writing app ios, , trying implement landscape views. trying support both ios 5 , ios 6, have autolayout disabled. when rotate landscape, layout loades correctly. rotate landscape, , when rotate portrait, uiimageview containing logo stretches underneath button , label.

from viewcontroller.m:

@interface viewcontroller ()  - (ibaction)showmenu:(id)sender;  @end  @implementation viewcontroller  @synthesize start, menubutton, vector_status, login_status, items, recordlength, countdown, change_name, iapi, running, timeover, setupdone, dfm, motionmanager, locationmanager, recorddatatimer, timer, testlength, expnum, sampleinterval, sessionname,geocoder,city,country,address,datatobejsoned,elapsedtime,recordingrate, experiment,firstname,lastinitial,username,usedev,password,session_num,managedobjectcontext,datasaver,x,y,z,mag,image ;

from appdelegate.m:

- (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {     self.window = [[uiwindow alloc] initwithframe:[[uiscreen mainscreen] bounds]];     // override point customization after application launch.     if ([[uidevice currentdevice] userinterfaceidiom] == uiuserinterfaceidiomphone) {         self.viewcontroller = [[viewcontroller alloc] initwithnibname:@"viewcontroller_iphone" bundle:nil];     } else {         self.viewcontroller = [[viewcontroller alloc] initwithnibname:@"viewcontroller_ipad" bundle:nil];     }         uinavigationcontroller *navigation = [[uinavigationcontroller alloc] initwithrootviewcontroller:self.viewcontroller];     navigation.navigationbar.barstyle = uibarstyleblackopaque;     self.window.rootviewcontroller = navigation;     nsuserdefaults *prefs = [nsuserdefaults standarduserdefaults];     [prefs setbool:yes forkey:@"y"];     self.viewcontroller.setupdone = yes;     [self.window makekeyandvisible];     return yes; } 

check autoresizingmask property of uiimageview. should uiviewautoresizingflexibleheight first.
