iOS Image in navigation Item titleview – Photoshop

I want to add an image in my navigation bar. To do this, i wrote that :

        self.navigationItem.titleView = [[UIImageView alloc] initWithImage: [UIImage imageNamed:@"logo.png"]];

It’s running, but the only problem is the image seems to be blurred.
When i look it on photoshop or other software, the image is perfect.

The size of this image is : 120 x 30px.

Someone to help me ? Thx

    First of all, please, print self.navigationItem.titleView.frame after your viewDidAppear.

    Seems to be, that in some case your titleView is placed with half-pixeled origin.x, or origin.y.

    Try to play with:

    [self.navigationController.navigationBar setTitleVerticalPositionAdjustment:<#(CGFloat)#> forBarMetrics:<#(UIBarMetrics)#>]

    Try to set different values to the first param and observe the result.

    You can change the navigation and status bar background only in iOS7. For this, you can use

    [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"yourImage.png"] forBarMetrics:UIBarMetricsDefault];

    The size should be 320*64 px

    and to change the Navigation Bar title

    self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"yourImage.png"]];
