NSString * CT = @ "^1 ((33|53|8[09)) [0-9]|349] \\d{7}$";

Nspredicate *regextestmobile = [Nspredicate predicatewithformat:@ "Self MATCHES%@", MOBILE];

Nspredicate *REGEXTESTCM = [Nspredicate predicatewithformat:@ "Self MATCHES%@", CM];

Nspredicate *REGEXTESTCU = [Nspredicate predicatewithformat:@ "Self MATCHES%@", CU];

Nspredicate *REGEXTESTCT = [Nspredicate predicatewithformat:@ "Self MATCHES%@", CT];

BOOL res1 = [Regextestmobile evaluatewithobject:self];

BOOL res2 = [REGEXTESTCM evaluatewithobject:self];

BOOL Res3 = [Regextestcu evaluatewithobject:self];

BOOL res4 = [REGEXTESTCT evaluatewithobject:self];

if (res1 | | res2 | | res3 | | res4) {

return YES;
