Swift标准库的高级扩展EZSwiftExtensions

对Swift标准库、 Foundation、UIKit 提供了很多高级扩展函数，包括以下内容： 

• NSObject 
• Bool 
• Int 
• Double 
• String 
• NSAttritedString 
• Array 
• Dictioanry 
• NSDate 
• NSTimer 
• CGRect 
• UIViewController 
• UIView 
• UITextView 
• UILabel 
• UIImageView 
• UIImage 
• Block Objects 
• UIDevice 
• NSUserDefauts 
• NSURL EZ function and variables

示例代码：

通过索引获取对象

var myArray = ["charmander","bulbasaur","squirtle"]
print(myArray.get(1)) // "bulbasaur"

随机获取对象

var myArray = ["charmander","bulbasaur","squirtle"]
print(myArray.random()) // bulbasaur or something else

通过对象获取索引

var myArray = ["charmander","bulbasaur","squirtle","charmander"]
print(myArray.indexesOf("charmander")) // [0,3]

检查数组中是否包含另一个数组

var myArray = ["charmander","bulbasaur","squirtle"]
print(myArray.containsArray(["charmander","bulbasaur"])) // true
print(myArray.containsArray(["string"])) // false

切换布尔值

var myBool: Bool = true
print(myBool.toggle()) // false

初始化颜色

let myColor = UIColor(r: 100, g: 100, b: 100) // Default alpha is 1

延迟执行代码

Timer.runThisAfterDelay(seconds: 2) { () -> () in
    print("Prints this 2 seconds later in main queue")
}

每秒执行代码

var count = 0
Timer.runThisEvery(seconds: 1) { (timer) -> Void in
    print("Will print every second")
    if count == 3 {
        timer?.invalidate()
    }
    count += 1
}

获取项目版本信息

print(ez.appVersion) // 0.3
print(ez.appBuild) // 7
print(ez.appVersionAndBuild) // v0.3(7)

检测屏幕截图

ez.detectScreenShot { () -> () in
    print("User took a screen shot")
}
