求助一个问题，如何让app启动时同时加载tabbar上其他页面的数据

Answer 1

如果登陆之前所有页面不可预览的话，可以这么做
也就是你所问的登陆成功后怎么跳转tabbar

- (UITabBarController *)tabBarController

{

_tabBarController = [[UITabBarController alloc] init];

_tabBarController.viewControllers = @[NAVIGATION(BXHomeVC),

NAVIGATION(BXProductVC),

NAVIGATION(BXMineVC)];

for (int i = 0; i<_tabBarController.viewControllers.count; i++) {

((UITabBarController *) _tabBarController.viewControllers[i]).tabBarItem.title = @[@"首页",

@"产品",

@"我的"][i];

((UITabBarController *) _tabBarController.viewControllers[i]).tabBarItem.image = [[UIImage imageNamed:[NSString stringWithFormat:@"tb%d",i]] imageWithRenderingMode:UIImageRenderingModeAutomatic];

}

_tabBarController.tabBar.tintColor = MAIN_COLOR;

_tabBarController.delegate = self;

return _tabBarController;

}
BXAppDelegate *delegate = (BXAppDelegate *)[UIApplication sharedApplication].delegate;

delegate.window.rootViewController = delegate.tabBarController;
