常用正则表达式

一些正则表达式以及objective-c下边的正则判断：

Require : /.+/,  
Email : /^\w+([-+.]\w+)*@\w+([-.]\\w+)*\.\w+([-.]\w+)*$/,  
Phone : /^((\(\d{3}\))|(\d{3}\-))?(\(0\d{2,3}\)|0\d{2,3}-)?[1-9]\d{6,7}$/,  
Mobile : /^((\(\d{3}\))|(\d{3}\-))?13\d{9}$/,  
Url : /^http:\/\/[A-Za-z0-9]+\.[A-Za-z0-9]+[\/=\?%\-&_~`@[\]\':+!]*([^<>""])*$/,  
IdCard : /^\d{15}(\d{2}[A-Za-z0-9])?$/,  
Currency : /^\d+(\.\d+)?$/,
Number : /^\d+$/,  
Zip : /^[1-9]\d{5}$/,  
QQ : /^[1-9]\d{4,8}$/,  
Integer : /^[-\+]?\d+$/,  
Double : /^[-\+]?\d+(\.\d+)?$/,  
English : /^[A-Za-z]+$/,  
Chinese :   /^[\u0391-\uFFE5]+$/,  
UnSafe :/^(([A-Z]*|[a-z]*|\d*|[-_\~!@#\$%\^&\*\.\(\)\[\]\{\}<>\?\\\/\'"]*)|.{0,5})$|\s/,

//验证码4位

    NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", pattern];
    return [pred evaluateWithObject:self];

}
 
//验证邮箱

}
 
//验证密码6-20
-(BOOL)VerPassword
