我有一个标签显示一个数字,我想将其更改为更高的数字,但是,我想为它添加一些耀斑.我想通过一个易于进出的曲线将数字增加到更高的数字,以便加速然后减慢速度.请问,如何在swift中实现这一点,这是我的代码.谢谢.

 let newValue : Double = 1000 
 let oldValue : Double = 500 

 timer = NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: Selector("countAnimation:"), userInfo: ["oldValue":oldValue, "newValue": newValue],  repeats: true)

func countAnimation(timer: NSTimer)
{
    let dict = timer.userInfo as? [String:AnyObject]
    var OldTotalValue : Double = (dict!["oldValue"] as? Double)!
    let newTotalValue : Double = (dict!["newValue"] as? Double)!

    OldTotalValue = OldTotalValue + 10


    if newTotalValue < OldTotalValue
    {
        timer.invalidate()
    }
  else

    {
         mylabel.text =  String(OldTotalValue)
    }
}

我有一个RSA公钥,看起来像

-----BEGIN PUBLIC KEY-----
MIIBIDANBgkqhkiG9w0BAQEFAAOCAQ0AMIIBCAKCAQEAvm0WYXg6mJc5GOWJ+5jk

EQIBAw==
-----END PUBLIC KEY-----

我想在python中找出这个键的模N和指数E是什么？

使用pycrypto包我可以这样加载到密钥:

from Crypto.PublicKey import RSA

# read the public key in:
public_key = RSA.importKey(open('key.pub', 'r').read())

但是遵循pycrypto的rsa模块的文档还不清楚如何提取较小的组件.我该怎么做呢？
