Answer 1

Set navigation title view like below

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

EDIT:
if you have big image then use below code

UIImage *img = [UIImage imageNamed:@"1.png"];
UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 30, 30)];
[imgView setImage:img];
// setContent mode aspect fit
[imgView setContentMode:UIViewContentModeScaleAspectFit];
self.navigationItem.titleView = imgView;
