超级猜图swift

代码太多，贴几个重点吧

通过plist初始化(kvc),可以很方便的对类的属性进行赋值

import UIKit

class Question: NSObject {
    var answer:NSString!
    var icon:NSString!
    var title:NSString!
    var options:NSArray!
    //加载文件，初始化对象数组
    class func loadQuestionOfFile()->[Question]
    {
        let datas:NSArray! = NSArray(contentsOfFile: NSBundle.mainBundle().pathForResource("questions", ofType: "plist")!)
        var temp:[Question] = []
        for data in datas
        {
            temp.append(Question.instance(data as! NSDictionary))
        }
        return temp
    }
    //传入字典，初始化对象
    class func instance(questionData:NSDictionary)->Question
    {
//        var temp = Question(answer:questionData["answer"] as! NSString,title:questionData["title"] as! NSString,icon:questionData["icon"] as! NSString,option:questionData["option"] as! NSArray)
//        self.init(answer:questionData["answer"] as! NSString,title:questionData["title"] as! NSString,icon:questionData["icon"] as! NSString,option:questionData["options"] as! NSArray)
        let temp = Question()
        //直接使用字典的键值对队完成对对象属性的肤赋值
        temp.setValuesForKeysWithDictionary(questionData as! [String : AnyObject])
        return temp
    }
}

kvc其它用法

//取出对象数组中对象的icon值
print((self.questions as NSArray).valueForKeyPath("icon")!)
//取出对象数组中对象的book值(是一个类)的name属性，这里执行会报错,oc使用点分割swift呢？
print(self.questions[0].valueForKeyPath("book.name"))

隐藏程序界面状态栏

override func prefersStatusBarHidden() -> Bool {
     return true
}

隐藏启动界面状态栏

General>Deployment Info>Hide status bar勾选就好了

修改状态栏 style

override func preferredStatusBarStyle() -> UIStatusBarStyle {
    return UIStatusBarStyle.LightContent//居中
}

删除子控件

self.answerButtonView.subviews.forEach({$0.removeFromSuperview()})

弹出框

var alert = UIAlertView(title: "提示", message: "后面没有题了", delegate: nil, cancelButtonTitle: "取消", otherButtonTitles: "确认", "测试A","测试B")

控件放到最顶层

self.view.bringSubviewToFront(self.imageView)
