描述：在类里添加此方法，用的时候直接调用即可。

//检测手机号码
- (BOOL)isMobileNumber:(NSString *)mobileNum
{

NSString * MOBILE = @"^1(3[0-9]|5[0-35-9]|8[025-9])\\d{8}$";
//移动
NSString * CM = @"^1(34[0-8]|(3[5-9]|5[017-9]|8[278])\\d)\\d{7}$";
//联通
NSString * CU = @"^1(3[0-2]|5[256]|8[56])\\d{8}$";
//电信
NSString * CT = @"^1((33|53|8[09])[0-9]|349)\\d{7}$";

NSPredicate *regextestmobile = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", MOBILE];
