检查一下,我正在将一个模态视图插入另一个模态视图内。但是,我试图在此模态视图中放置一个按钮,但没有运气。
我做错了什么?
谢谢!
CadastroViewController *addController = [[CadastroViewController alloc] initWithNibName:@"CadastroViewController" bundle:nil];
// This is where you wrap the view up nicely in a navigation controller
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:addController];
// You can even set the style of stuff before you show it
navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;
navigationController.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"OK" style:UIBarButtonItemStyleBordered target:self action:@selector(buy)];
// And now you want to present the view in a modal fashion all nice and animated
[self presentModalViewController:navigationController animated:YES];
// make sure you release your stuff
[navigationController release];
[addController release];
最佳答案
您必须将新的 UINavigationItem 添加到实际 View Controller 的导航栏 - 而不是导航 Controller 。
addController.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"OK" style:UIBarButtonItemStyleBordered target:self action:@selector(buy)];
