iOS自定义NavigationBar

最近忙着搭建页面，昨天网上做选址界面的时候，需要在NavigationBar的title位置放一个UISegmentControl，

于是学习了一下怎样处理，现在学会了与大家分享，放什么控件都行，只要是UIView的子类~

万变不离其宗~ 

        UISegmentedControl *segmentControl = [[UISegmentedControl alloc]initWithFrame:CGRectMake(0, 0, 150, 30)];        segmentControl.tintColor =  [UIColor whiteColor];        [segmentControl insertSegmentWithTitle:@"按地市" atIndex:0 animated:YES];        [segmentControl insertSegmentWithTitle:@"按拼音" atIndex:1 animated:YES];        segmentControl.selectedSegmentIndex = 0;        self.navigationItem.titleView = segmentControl;
