iPhone：如何在iPhone中显示像控制器与图像的弹出视图？

问题描述：

我想在iPhone中使用图像显示小型弹出视图（就像在iPad中弹出视图，但在这里我想在iPhone中）。iPhone：如何在iPhone中显示像控制器与图像的弹出视图？

我该怎么做？

您以前的问题的可能重复：[如何在iPad中实现模态弹出视图？就像Facebook屏幕使用共享包？]（http://*.com/questions/5769035/how-to-implement-modal-popup-view-in-ipad-like-facebook-screen-using-sharekit） – 2011-05-21 17:02:08

@Josh：嘿，我要求包括里面的图像与iPhone的弹出效果。不适用于modalpresentview。 – Devang 2011-05-22 03:25:06

@devang你一定会明白这一点http://iosdevelopertips.com/open-source/ios-open-source-popover-api-for-iphone-wepopover.html

另一种方法是Mehul建议的。如果您遇到与iPad中的UIPopover相对应的内容，请告诉我们。

尼斯链接。但它只会允许文字而不是图像。我想显示图像。 – Devang 2011-05-22 03:16:36

可以动态采取的UIView，然后在此的UIView添加的UIImageView就这样

UIView *tmpView = [[UIView alloc] initWithFrame:CGRectMake(XPosition, YPosition, Width, Height)];  
    UIImage *tmpImg = [UIImage imageNamed:@"YourImageName.png"]; 
    UIImageView *tmpImgView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, tmpImg.size.width, tmpImg.size.height)]; 
    tmpImgView.image = tmpImg; 
    [self.view addSubview:tmpView];

希望这会工作....

但它不会像Popoverview在iPad中给出的效果一样。我想在iPhone中有相同的效果！ – Devang 2011-05-22 03:06:30

CollectionView可以在屏幕上弹出。下面是完整代码显示的CollectionView的弹出和隐藏弹出窗口

import UIKit 

class ViewController: UIViewController , UICollectionViewDataSource, UICollectionViewDelegate { 

    //let popView = UICollectionView.init(frame: CGRect(x:8,y:30,width:304,height:200)) 

    var demoCollectionView:UICollectionView? = nil; 

    @IBOutlet var button: UIButton! 

    override func viewDidLoad() { 
     super.viewDidLoad() 
     // Do any additional setup after loading the view, typically from a nib. 
     self.loadColorCollectionView() 

    } 

    func loadColorCollectionView() { 
     let layout: UICollectionViewFlowLayout = UICollectionViewFlowLayout() 
     layout.sectionInset = UIEdgeInsets(top: 20, left: 10, bottom: 10, right: 10) 
     layout.itemSize = CGSize(width: 30, height: 30) 

     demoCollectionView = UICollectionView(frame: CGRect(x:8,y:20,width:304,height:200), collectionViewLayout: layout) 


     demoCollectionView?.dataSource = self 
     demoCollectionView?.delegate = self 
     demoCollectionView?.register(UICollectionViewCell.self, forCellWithReuseIdentifier: "Cell") 
     demoCollectionView?.backgroundColor = UIColor.white 
    } 

    override func didReceiveMemoryWarning() { 
     super.didReceiveMemoryWarning() 
     // Dispose of any resources that can be recreated. 
    } 

    func numberOfSections(in collectionView: UICollectionView) -> Int { 
     return 1; 
    } 

    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { 
     return 200; 
    } 

    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { 
     let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath); 

     if indexPath.row%2 == 0 { 
     cell.backgroundColor = UIColor.red; 
     } 
     else{ 
      cell.backgroundColor = UIColor.blue; 
     } 
     return cell; 
    } 

    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) { 

     guard let statusBar = UIApplication.shared.value(forKeyPath: "statusBarWindow.statusBar") as? UIView else { return } 

     if indexPath.row%2 == 0 { 
      statusBar.backgroundColor = UIColor.red; 
     } 
     else{ 
      statusBar.backgroundColor = UIColor.blue; 
     } 
     self.demoCollectionView?.removeFromSuperview() 

    } 

    @IBAction func showMessage() { 

     //popView.backgroundColor = UIColor.darkGray; 
     //self.view.addSubview(popView) 


     self.view.addSubview(demoCollectionView!) 
    } 

    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) { 
     //self.popView.removeFromSuperview() 
     self.demoCollectionView?.removeFromSuperview() 


    } 

}

我在ViewController中创建了一个按钮，并呼吁showMessage按钮（）函数，点击它会弹出颜色的CollectionView。在选择颜色弹出将消失。
