添加NSString分类
1.在NSString+Check.h中，添加方法；
-(BOOL)checkPhoneNumInput;
2.在NSString+Check.m文件中；
-(BOOL)checkPhoneNumInput{
NSString * MOBILE = @"^1(3[0-9]|5[0-35-9]|8[025-9]|70|76|77)\d{8}$";
NSString * CM = @"^1(34[0-8]|(3[5-9]|5[017-9]|8[278])\d)\d{7}$";
NSString * CU = @"^1(3[0-2]|5[256]|8[56])\d{8}$";
NSString * CT = @"^1((33|53|8[09])[0-9]|349)\d{7}$";
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;
} else {
return NO;
}
}
3.在需要的地方导入#import "NSString+Check.h"
4.使用方法：
BOOL isPhoneNum = [self.phoneTextField.text checkPhoneNumInput];
