UIToolbar
- 一般在View的最上面或者最下面，可以加入UIBarButtonItem
- UIBarItem可以通过storyboard拖拽实现，也可以通过alloc/init方法
UISplitViewController
- 只能在IPad Storyboard使用
- 只能作为base UI element
如何使用？
- 默认藏在bar button后面
- (BOOL)splitViewController:(UISplitViewController *)sender
shouldHideViewController:(UIViewController *)master
inOrientation:(UIInterfaceOrientation)orientation
{
return YES; // always hide it
}
- 永远不藏在bar button 后面
- (BOOL)splitViewController:(UISplitViewController *)sender
shouldHideViewController:(UIViewController *)master
inOrientation:(UIInterfaceOrientation)orientation
{
return NO; // never hide it
}
- 在portrait模式藏在UIViewController后面
- (BOOL)splitViewController:(UISplitViewController *)sender
shouldHideViewController:(UIViewController *)master
inOrientation:(UIInterfaceOrientation)orientation
{
return UIInterfaceOrientationIsPortrait(orientation);
}
Popover
如何设置popover大小:
- 在viewController里面inspect
- 在content VC controller 里面设置
@property (nonatomic) CGSize contentSizeForViewInPopover;
- 给popover controller发送消息
- (void)setPopoverContentSize:(CGSize)size animated:(BOOL)animated;
