objective-c - UITabBar自定义

Question

这看起来不太可能，但有没有人知道一种方法:

1. 在屏幕顶部放置一个 UITabBar
2. 改变它的高度

欢迎大家推荐私有(private)API方法

Answer 1

您不需要私有(private) API，只需在您的 applicationDidFinishLaunching 方法中尝试即可。

controller = [[UITabBarController alloc] initWithNibName:nil bundle:nil];

HeadlinesViewController *headlines = [[HeadlinesViewController alloc] init];
OpinionsViewController *opinions = [[OpinionsViewController alloc] init];

controller.viewControllers = [NSArray arrayWithObjects:headlines, opinions, nil];

    // set your position , width and height there
controller.tabBar.frame = CGRectMake(0, 20, 320, 50);
[window addSubview:controller.view ];
[window makeKeyAndVisible];
