iOS开发中杂七杂八的东西

1、实现APP直接跳转到App Store搜索界面

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms-apps://itunes.apple.com/WebObjects/MZStore.woa/wa/search?"]];

2、去掉UITabBarController顶部黑线

UIImage *image = [UIImage imageNamed:@"white"];

[tabBarController.tabBar setBackgroundImage:image];

[tabBarController.tabBar setShadowImage:image];
