您好我想在我的应用程序中上下支持肖像,主页按钮我该怎么做?
我转到我的项目设置,检查这两个
我添加下面的代码
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationIsPortrait(interfaceOrientation);
}
我也试过
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}
但似乎没有工作
任何帮助
答案 0 :(得分:2)
试试这个
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
if((interfaceOrientation == UIInterfaceOrientationPortrait) || (interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)){
return YES;
}
return NO;
}
如果它仍然不起作用,你可以尝试这个(只是为了测试)
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
return YES;
}
如果这不起作用,要么您没有弄乱右视图控制器,要么父/根视图控制器已禁用旋转(在rootVC的shouldAutoRotate方法中返回NO)
