ipad - youtube in iframe via uiwebview specify dimensions that don't cut off when rotated to landscape -

i'm making ipad app loads youtube video. able uiwebview load youtube video iframe code found online. need able rotate ipad , not have video cropped when rotated landscape @ same time both landscape , portrait width full width of device. put in iframe? i've tried use

"meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=no"  

but didn't work. tried place in iframe script (not between within . cannot right. ideas? appreciated. here's code below:

.m

#import "viewcontroller.h" #import <avfoundation/avfoundation.h>  @interface viewcontroller ()  @end  @implementation viewcontroller  @synthesize webview;  -(void)viewdidload {     [super viewdidload];    [self embedyoutube];     nslog(@"frame:%@", nsstringfromcgrect(self.view.frame)); // prints frame:{{0, 0}, {768, 1004}}    nslog(@"bounds:%@", nsstringfromcgrect([[self view] bounds])); // prints frame:{{0, 0}, {768, 1004}}  }  -(void)embedyoutube{      avaudiosession *audiosession = [avaudiosession sharedinstance];     bool ok;     nserror *setcategoryerror = nil;     ok = [audiosession setcategory:avaudiosessioncategoryplayback                          error:&setcategoryerror];     if (!ok) {         nslog(@"%s setcategoryerror=%@", __pretty_function__, setcategoryerror); }        nsstring *embedhtml = @"<iframe height=\"700\" width=\"900\" src=\"http://www.youtube.com/embed/qk8mjjjvaes\" frameborder=\"0\" allowfullscreen></iframe>";        nsstring *html = [nsstring stringwithformat:embedhtml];      [webview loadhtmlstring:html baseurl:nil];     [self.view addsubview:webview];  }  - (void)didreceivememorywarning {     [super didreceivememorywarning];     // dispose of resources can recreated. }  @end 

in appdelegate.m file, have:

- (bool)shouldautorotatetointerfaceorientation:(uiinterfaceorientation)interfaceorientation { // support rotation in view controller return yes; } 

.xib

both view , webview have autoresize subviews checked, orientation view portrait, size view none, both mode center , webview scales fit page.

i ended figuring out exact dimensions give xcode aspect ratio calculator.

-(void)embedyoutube{      avaudiosession *audiosession = [avaudiosession sharedinstance];     bool ok;     nserror *setcategoryerror = nil;     ok = [audiosession setcategory:avaudiosessioncategoryplayback                      error:&setcategoryerror];     if (!ok) {     nslog(@"%s setcategoryerror=%@", __pretty_function__, setcategoryerror);     }      nsstring *embedhtml = @"<iframe height=\"548\" width=\"975\" src=\"http://www.youtube.com/embed/qk8mjjjvaes\" frameborder=\"0\" allowfullscreen></iframe>";      nsstring *html = [nsstring stringwithformat:embedhtml];     [webview loadhtmlstring:html baseurl:nil];    [self.view addsubview:webview];  }
