ios - How to put an image in the center of navigationBar of a UIViewController? -

-

i have snippet of code used in viewdidload of uiviewcontroller. i'va no errors. images exists. background not image. image sort of logo.

if ([self.navigationcontroller.navigationbar respondstoselector:@selector(setbackgroundimage:forbarmetrics:)] ) {      /* background of navigationbar. */     uiimage * navigationbarimage = [uiimage imagenamed:@"01_navbar_portrait.png"];     [self.navigationcontroller.navigationbar setbackgroundimage:navigationbarimage forbarmetrics:uibarmetricsdefault];      /* image in navigationbar */     uiimage * logoinnavigationbar = [uiimage imagenamed:@"01_logo.png"];     uiimageview * logoview = [[uiimageview alloc] init];     [logoview setimage:logoinnavigationbar];     self.navigationcontroller.navigationitem.titleview = logoview;  }

the uinavigationcontroller manages navigation bar looking @ navigationitem property of top-most view controller on navigation stack. change view logo, need set in view controller uses logo (i.e. root view controller or 1 gets pushed on stack).

do in viewdidload of view controller:

uiimage* logoimage = [uiimage imagenamed:@"logo.png"]; self.navigationitem.titleview = [[uiimageview alloc] initwithimage:logoimage];

in case, setting wrong navigation item:

// oops... self.navigationcontroller.navigationitem.titleview = logoview; // should this: self.navigationitem.titleview = logoview;
