iphone - Set UIBarStyle of UIImagePickerController -

-

i set bar style of uiimagepickercontroller following, bar still uibarstyleblacktranslucent. possible set bar style of uiimagepickercontroller? in advance!

uiimagepickercontroller *imagepicker = [[uiimagepickercontroller alloc] init]; imagepicker.sourcetype = uiimagepickercontrollersourcetypephotolibrary;         imagepicker.navigationbar.barstyle = uibarstyleblack;

i can set tint color through:

imagepicker.navigationbar.tintcolor = uicolorfromrgb(0xcc6600);

here's worked me (you need test class of navigationcontroller, not viewcontroller being presented, , need set non-transparent background color seems)

- (void)navigationcontroller:(uinavigationcontroller *)navigationcontroller       willshowviewcontroller:(uiviewcontroller *)viewcontroller                     animated:(bool)animated {     if ([navigationcontroller iskindofclass:[uiimagepickercontroller class]])     {         navigationcontroller.navigationbar.barstyle = uibarstyleblack;         navigationcontroller.navigationbar.backgroundcolor = [uicolor blackcolor];     } }
