Swift中用正规表达式判断String是否是手机号码

简单地贴个代码就走_{防止以后忘了难找}也希望对不知道的同学们有帮助

func isTelNumber(num:NSString)->Bool
{
    var mobile = "^1(3[0-9]|5[0-35-9]|8[025-9])\\d{8}$"
    var  CM = "^1(34[0-8]|(3[5-9]|5[017-9]|8[278])\\d)\\d{7}$"
    var  CU = "^1(3[0-2]|5[256]|8[56])\\d{8}$"
    var  CT = "^1((33|53|8[09])[0-9]|349)\\d{7}$"
    var regextestmobile = NSPredicate(format: "SELF MATCHES %@",mobile)
    var regextestcm = NSPredicate(format: "SELF MATCHES %@",CM )
    var regextestcu = NSPredicate(format: "SELF MATCHES %@" ,CU)
    var regextestct = NSPredicate(format: "SELF MATCHES %@" ,CT)
    if ((regextestmobile.evaluateWithObject(num) == true)
        || (regextestcm.evaluateWithObject(num)  == true)
        || (regextestct.evaluateWithObject(num) == true)
        || (regextestcu.evaluateWithObject(num) == true))
    {
        return true
    }
    else
    {
        return false
    }  
}
