Popover view for iPhone using XCode 5
提问by Sèb
I wanted to reuse the popover for iPhone described in this videowhich is exactly what I need.
我想重用本视频中描述的 iPhone 弹出窗口，这正是我所需要的。
The problem is that I couldn't bind a UIViewControllerproperty to the popover's UIViewControllerlike in the video.
问题是我无法将UIViewController属性绑定到UIViewController视频中的弹出窗口。
One difference with the video is that it has been made using XCode 4.2 and I'm using XCode 5.
与视频的一个区别是它是使用 XCode 4.2 制作的，而我使用的是 XCode 5。
So the question is: How to make a popover for iPhone like in the videoon XCode 5?
所以问题是：如何像XCode 5 上的视频那样为 iPhone 制作一个弹出框？

I figured out a way to get popover to work on iPhone and iPad programmatically !
我想出了一种让 popover 以编程方式在 iPhone 和 iPad 上工作的方法！
Create a category to make popover available on iPhone (more details here)
//UIPopover+Iphone.h @interface UIPopoverController (overrides) + (BOOL)_popoversDisabled; @end //UIPopover+Iphone.m @implementation UIPopoverController (overrides) + (BOOL)_popoversDisabled { return NO; } @endCreate the button which will show the popover and implement the method it calls
创建一个类别以使 iPhone 上的 popover 可用（更多详细信息在这里）
//UIPopover+Iphone.h @interface UIPopoverController (overrides) + (BOOL)_popoversDisabled; @end //UIPopover+Iphone.m @implementation UIPopoverController (overrides) + (BOOL)_popoversDisabled { return NO; } @end创建将显示弹出窗口的按钮并实现它调用的方法
ExampleUIViewController.h
示例UIViewController.h
@interface ExampleViewController : UIViewController <UIPopoverControllerDelegate>
@property (strong, nonatomic) UIButton *detailButton;
@property (nonatomic, retain) IBOutlet UIPopoverController *poc;
UIPopoverController poc has to be held in an instance variable, more details here.
UIPopoverController poc 必须保存在一个实例变量中，更多细节在这里。
ExampleUIViewController.m
示例UIViewController.m
- (void)viewDidLoad {
_detailButton = [UIButton buttonWithType:UIButtonTypeCustom];
[_detailButton addTarget:self
action:@selector(showPop:)
forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:_detailButton];
}
-(void)showPop:(UIButton *)button {
UIViewController *detailsViewController = [[DetailsViewController alloc] initWithNibName:@"DetailsViewController" bundle:nil];
self.poc = [[UIPopoverController alloc] initWithContentViewController:detailsViewController];
[self.poc setDelegate:self];
[self.poc presentPopoverFromRect:_detailButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];
}
- Create the UIViewController that will contain what's displayed inside the popover (called DetailsViewController in the example)
- 创建 UIViewController ，它将包含弹出框内显示的内容（在示例中称为 DetailsViewController）
Simply create it in your project by a right click -> New File -> Objective c class -> UIViewController and tick the box "With XIB".
只需通过右键单击 -> 新建文件 -> Objective c 类 -> UIViewController 在您的项目中创建它，然后勾选“With XIB”框。
Then a popover will appear right next to the button when tapped.
然后点击时按钮旁边会出现一个弹出窗口。
Tested OK on iOs5 and above.
在 iOs5 及更高版本上测试正常。
