如何修改tabBar的高度

在TabBarViewController里面设置

@implementation SuerTabBarViewController

- (void)viewWillLayoutSubviews{

CGRect tabFrame = self.tabBar.frame; self.TabBar is IBOutlet of your TabBar

tabFrame.size.height = 80;//高度80可以修改

tabFrame.origin.y = self.view.frame.size.height - 80;

self.tabBar.frame = tabFrame;

}
