ps做网站 大小,seo培训价格,办理个人公司需要什么手续,深圳网约车哪个平台好今天到UITabBarController 结合 UIPickView, 这里一共有5个实现, 由浅到易。 其实在IB上面使用UITabBarController很简单, 就像平常拖控件一样拖到界面上面, 然后把Tab Bar Item拉到UITabBarController就可以增加底下的tab, 再分别指定底下tab就可以关联到对应的ViewController…

今天到UITabBarController 结合 UIPickView, 这里一共有5个实现, 由浅到易。

其实在IB上面使用UITabBarController很简单, 就像平常拖控件一样拖到界面上面, 然后把Tab Bar Item拉到UITabBarController就可以增加底下的tab, 再分别指定底下tab就可以关联到对应的ViewController。

BIDAppDelegate.h

#import <UIKit/UIKit.h>@interface BIDAppDelegate : UIResponder <UIApplicationDelegate>@property (strong, nonatomic) UIWindow *window;
@property (strong, nonatomic) IBOutlet UITabBarController *rootController;@end

 

BIDAppDelegate.m

#import "BIDAppDelegate.h"@implementation BIDAppDelegate- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];// Override point for customization after application launch.[[NSBundle mainBundle] loadNibNamed:@"TabBarController" owner:self options:nil];    // 因为与IB做了IBOutlet的关联, 所以以这种方式加载xib到对应的controllerself.window.rootViewController = self.rootController;    // 与IB做了IBOutlet的关联self.window.backgroundColor = [UIColor whiteColor];[self.window makeKeyAndVisible];return YES;
}@end
