Question

我是一个iOS菜鸟，很抱歉。

我提出了a sample Search app (full code here)问题，当我点击搜索栏时，它没有打开键盘

有人可以帮忙吗？

这是我的viewController.swift文件：

class ViewController: UIViewController, UISearchBarDelegate {

    @IBOutlet weak var scrollView: UIScrollView!

    let instagramClientID = "xxxxxx"

    func searchInstagramByHashtag(searchString: String) {
        for subview in self.scrollView.subviews {
            subview.removeFromSuperview()
        }

        let instagramURLString = "https://api.instagram.com/v1/tags/" + searchString + "/media/recent?client_id=" + instagramClientID

        let manager = AFHTTPRequestOperationManager()

       self.scrollView.alpha = 0.0

        let activityIndictorView = UIActivityIndicatorView(activityIndicatorStyle: UIActivityIndicatorViewStyle.Gray)
        activityIndictorView.center = self.view.center
        self.view.addSubview(activityIndictorView)
        activityIndictorView.startAnimating()

        manager.GET( instagramURLString,
            parameters: nil,
            success: { (operation: AFHTTPRequestOperation!,responseObject: AnyObject!) in
                println("JSON: " + responseObject.description)

                if let dataArray = responseObject.valueForKey("data") as? [AnyObject] {
                    self.scrollView.contentSize = CGSizeMake(320, CGFloat(320*dataArray.count))
                    for var i = 0; i < dataArray.count; i++ {
                        let dataObject: AnyObject = dataArray[i]
                        if let imageURLString = dataObject.valueForKeyPath("images.standard_resolution.url") as? String {
                            println("image " + String(i) + " URL is " + imageURLString)



                            let imageView = UIImageView(frame: CGRectMake(0, CGFloat(320*i), 320, 320))
                            self.scrollView.addSubview(imageView)
                            imageView.setImageWithURL( NSURL(string: imageURLString))

                            activityIndictorView.stopAnimating()

                            UIView.animateWithDuration(1.0, animations: {
                                self.scrollView.alpha = 1.0
                                }, completion: {
                                    (value: Bool) in
                                    println("Animation complete!")
                            })

                        }
                    }
                }
            },
            failure: { (operation: AFHTTPRequestOperation!,error: NSError!) in
                println("Error: " + error.localizedDescription)
        })
    }

    func searchBarSearchButtonClicked(searchBar: UISearchBar!) {

        //println("search bar clicked!")

        searchBar.resignFirstResponder()
        searchInstagramByHashtag(searchBar.text)
    }

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

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

}

可以使用iOS模拟器进行设置。转到iOS模拟器 - ＆gt;硬件 - ＆gt;键盘 - ＆gt;取消选择＆＃34;连接硬件键盘＆＃34;或选择＆＃34;切换软件键盘＆＃34;。
