I m非常新颖的SOS发展公司,我刚刚在我的西比档案中制作了一部<条码>:纳吉特·巴尔<代码>,我想在用户(如照片)利用一部分屏幕时隐藏/how。 我在网上发现了一些幻灯,但我不知道如何使用。
如果有人能向我提供详细信息,说明如何做到这一点,我不胜感激。

在贵方言中,在任何地方都添加这种 to。 这在第一大街上藏匿,在第二大街上再次露面。
- (void)toggleNavBar:(UITapGestureRecognizer *)gesture {
BOOL barsHidden = self.navigationController.navigationBar.hidden;
[self.navigationController setNavigationBarHidden:!barsHidden animated:YES];
}
如果没有导航控制器,将航道与IBOutlet连接起来,替换为
- (void)toggleNavBar:(UITapGestureRecognizer *)gesture {
BOOL barsHidden = self.navBar.hidden;
self.navBar.hidden = !barsHidden;
}
然后在<代码>-(撤销)viewDidLoad中添加以下内容:{}
UITapGestureRecognizer *gesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(toggleNavBar:)];
[self.view addGestureRecognizer:gesture];
[gesture release];
如果要主人的看法是: 观点主计长必须把议定书添加到观点控制器上,并把它作为代表列入<条码> 姿态.delegate = 自我;后添加如下内容:
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer
shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
return YES;
}
之所以需要这一点,是因为国际交易日志管理人已经实施自己的姿态识别器。
归根结底,你要向您的航标发出-setHidden:
。 在您看来,这样做最容易的方式是把Outlet<>m>和Action列入你的控制员。 然后,在您的书目中,将航道与散射线连接起来,并将一些纽州(甚至一个大型、完整的屏幕)与行动联系起来。
Outlets and Actions are basic techniques used over and over in iOS (and Mac) programming, so if you don t understand them, best go read up on them now. Every beginning iOS/Mac programming book covers this topic as does Apple s own Getting Started guide (pay particular attention to the Configuring the View section).
在你的行动中,向散列发出这样的信息:
-(void)myButtonAction:(id)sender{
[[self myNavigationBarOutlet] setHidden:YES];
}
每当你吨被开发时,这将掩盖航道。
(假设有<条码>。) Bar , 如同你所说的那样。 如果你重新使用管理自己的<条码>的“冻结令”/代码,这些指示将有所不同。 Bar
