iPhone 修改navigation bar 字体和颜色

- (void)setTitle:(NSString *) title

{

[super setTitle:title];

UILabel *titleView = (UILabel *)self.navigationItem.titleView;

if(!titleView){

titleView = [[UILabel alloc] initWithFrame:CGRectZero];

titleView.backgroundColor = [UIColor clearColor];

titleView.font = [UIFont boldSystemFontOfSize:20.0];

titleView.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];

titleView.textColor = [UIColor blackColor];

self.navigationItem.titleView = titleView;

}

titleView.text = title;

[titleView sizeToFit];

}
