因此,我一直在尋找各地的示例如何創建一個uitabbar prpgrammatically。我盡我所能從每個示例中獲取所需的內容,並將我希望我的應用程序的外觀如下所示:在2選項卡欄後面的歡迎屏幕。無法讓我的uitabbar以編程方式設置時出現
我有一個UIButton的歡迎屏幕上移動視圖控制器:
-(IBAction)aMethod:(id)sender {
MyTabProjectViewController *controller = [[MyTabProjectViewController alloc] initWithNibName:nil bundle:nil];
controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:controller animated:YES];
}
Then in my MyTabProjectViewController.m I do this:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
//Setting up the view
UIView *contentView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
contentView.backgroundColor = [UIColor whiteColor];
self.view = contentView;
//Declaring all view controllers
FirstView *first = [[FirstView alloc] init];
SecondView *second = [[SecondView alloc] init];
//Set titles for the view controllers
first.title = @"First";
second.title = @"Second";
UITabBarController *tabBarController = [[UITabBarController alloc] init];
tabBarController.view.frame = CGRectMake(0, 0, 320, 460);
UINavigationController *nvc1 = [[UINavigationController alloc] initWithRootViewController:first];
UINavigationController *nvc2 = [[UINavigationController alloc] initWithRootViewController:second];
nvc1.navigationBar.barStyle = UIBarStyleBlack;
nvc2.navigationBar.barStyle = UIBarStyleBlack;
NSArray *controllers = [[NSArray alloc] initWithObjects:nvc1, nvc2, nil];
self.tabBarController.viewControllers = controllers;
[self.view addSubview:tabBarController.view];
}
從某種原因,沒有什麼作品。當我點擊按鈕去MyTabProjectViewController時,我看到一個空白頁面。
我看到你的方法泄漏,試圖釋放控制器[控制器釋放];後presentModal ... – Mat
使用垃圾收集...沒有泄漏:)謝謝! – TommyG
你必須釋放它,我認爲你必須在contentView,第一,第二,tabBarController,nvc1,nvc2和控制器上調用release;如果你正在實例化一個非ivar,爲什麼你在使用它之後不會釋放它? – Mat
