Size of Image on UINavigationBar

Question

I want to put Custom image on my UINavigationBar,

When i tried this two code snippets,

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

And

    UIButton *logoView = [[UIButton alloc] initWithFrame:CGRectMake(0,0,70,30)];
    [logoView setBackgroundImage:[UIImage imageNamed:@"logo.png"] forState:UIControlStateNormal];
    [logoView setUserInteractionEnabled:NO];
    self.navigationItem.titleView = logoView;

image which i can see on my Device is getting blur or it is getting streched.

I made image with Resolution of 180*40(Width*Height)

I want to know the exact size of Image. what, it would be ?

Thanks in advance.

Answer 1

use this

UIImageView *navigationImage=[[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 98, 34)];
navigationImage.image=[UIImage imageNamed:@"topNav-logo.png"];

UIImageView *workaroundImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 98, 34)];
    [workaroundImageView addSubview:navigationImage];
    self.navigationItem.titleView=workaroundImageView;

hope this helps.
