根据需求,修改系统TabBar的高度
在继承UITabBarController的控制器中
- (void)viewDidLayoutSubviews {
[super viewDidLayoutSubviews];
CGRect frame = self.tabBar.frame;
frame.size.height = 55;
frame.origin.y = self.view.frame.size.height - frame.size.height;
self.tabBar.frame = frame;
// self.tabBar.backgroundColor = [UIColor whiteColor];
// self.tabBar.barStyle = UIBarStyleBlack;
// 此处需要设置barStyle,否则颜色会分成上下两层
}
