iOS工具 - 判断字符串是否为手机号码

判断字符串是否为手机号码

1 - 在实际开发中，往往需要判定手机号码

2 - 代码封装：我们对  NSString 进行扩展

// - NSString+isPhoneNumber.h

#import <Foundation/Foundation.h>
@interface NSString (isPhoneNumber)

// 判断是否是手机号码
+ (BOOL)isMobileNumber:(NSString *)mobileNum;

@end

// - NSString+isPhoneNumber.m

#import "NSString+isPhoneNumber.h"
@implementation NSString (isPhoneNumber)

// 判断是否是手机号码
+ (BOOL)isMobileNumber:(NSString *)mobileNum{
    
    if (mobileNum.length != 11){
        return NO;
    }
    /**
