Question

I am using a “defensive” code to set a custom image to UINavigationBar bar – it works well on devices with ios5 or later.

After some answers, I am editing the code with a combined answer (see below)

Is this is right & elegant way to do this?

if ([[UINavigationBar class] respondsToSelector:@selector(appearance)]) {
        UIImage *backgroundImage = [UIImage imageNamed:@"tableTitleView.png"];
        [self.navigationController.navigationBar setBackgroundImage:backgroundImage forBarMetrics:UIBarMetricsDefault];
    }
    else
    {

        NSString *barBgPath = [[NSBundle mainBundle] pathForResource:@"tableTitleView" ofType:@"png"];
        [self.navigationController.navigationBar.layer setContents:(id)[UIImage imageWithContentsOfFile: barBgPath].CGImage];
    }

Answer 1

float version = [[[UIDevice currentDevice] systemVersion] floatValue];
        NSLog(@"%f",version);
        if (version >= 5.0) {
            UIImage *backgroundImage = [UIImage imageNamed:@"Myimage.png"];
            [self.navigationController.navigationBar setBackgroundImage:backgroundImage forBarMetrics:UIBarMetricsDefault];
        }
        else
        {

            NSString *barBgPath = [[NSBundle mainBundle] pathForResource:@"Myimage" ofType:@"png"];
            [self.navigationController.navigationBar.layer setContents:(id)[UIImage imageWithContentsOfFile: barBgPath].CGImage];
        }

Maybe it will help you. it works for me.
