篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了一些常用的正则表达式（手机号身份证号邮箱等判断）相关的知识，希望对你有一定的参考价值。
1. 判断手机号码格式是否正确，利用正则表达式验证
+ (BOOL)isMobileNumber:(NSString *)mobileNum{ if (mobileNum.length != 11) { return NO; } /** * 手机号码: * 13[0-9], 14[5,7], 15[0, 1, 2, 3, 5, 6, 7, 8, 9], 17[6, 7, 8], 18[0-9], 170[0-9] * 移动号段: 134,135,136,137,138,139,150,151,152,157,158,159,182,183,184,187,188,147,178,1705 * 联通号段: 130,131,132,155,156,185,186,145,176,1709 * 电信号段: 133,153,180,181,189,177,1700 */ NSString *MOBILE = @"^1(3[0-9]|4[57]|5[0-35-9]|8[0-9]|70)\d{8}$"; /** * 中国移动：China Mobile * 134,135,136,137,138,139,150,151,152,157,158,159,182,183,184,187,188,147,178,1705 */ NSString *CM = @"(^1(3[4-9]|4[7]|5[0-27-9]|7[8]|8[2-478])\d{8}$)|(^1705\d{7}$)"; /** * 中国联通：China Unicom * 130,131,132,155,156,185,186,145,176,1709 */ NSString *CU = @"(^1(3[0-2]|4[5]|5[56]|7[6]|8[56])\d{8}$)|(^1709\d{7}$)"; /** * 中国电信：China Telecom * 133,153,180,181,189,177,1700 */ NSString *CT = @"(^1(33|53|77|8[019])\d{8}$)|(^1700\d{7}$)"; NSPredicate *regextestmobile = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", MOBILE]; NSPredicate *regextestcm = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CM]; NSPredicate *regextestcu = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CU]; NSPredicate *regextestct = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", CT]; if (([regextestmobile evaluateWithObject:mobileNum] == YES) || ([regextestcm evaluateWithObject:mobileNum] == YES) || ([regextestct evaluateWithObject:mobileNum] == YES) || ([regextestcu evaluateWithObject:mobileNum] == YES)) { return YES; } else { return NO; }}2. 判断邮箱格式是否正确，利用正则表达式验证
+ (BOOL)isAvailableEmail:(NSString *)email{ NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex]; return [emailTest evaluateWithObject:email];}3. 判断字符串中是否含有空格
+ (BOOL)isHaveSpaceInString:(NSString *)string{ NSRange _range = [string rangeOfString:@" "]; if (_range.location != NSNotFound) { return YES; }else { return NO; }}4. 判断字符串中是否含有中文
+ (BOOL)isHaveChineseInString:(NSString *)string{ for(NSInteger i = 0; i < [string length]; i++){ int a = [string characterAtIndex:i]; if (a > 0x4e00 && a < 0x9fff) { return YES; } } return NO;}5. 判断字符串是否全部为数字
+ (BOOL)isAllNum:(NSString *)string{ unichar c; for (int i=0; i<string.length; i++) { c="[string characterAtIndex:i];" if (!isdigit(c)) {="" return no;="" }="" }="" return yes;="" }<="" pre=""><p>判断是否是纯数字</p><pre class="brush:js;toolbar:false">+ (BOOL)isPureInteger:(NSString *)str { NSScanner *scanner = [NSScanner scannerWithString:str]; NSInteger val; return [scanner scanInteger:&val] && [scanner isAtEnd];}6. 过滤一些特殊字符
+ (NSString *)filterSpecialWithString:(NSString *)string{ // 定义一个特殊字符的集合 NSCharacterSet *set = [NSCharacterSet characterSetWithCharactersInString: @"@／：；: ;（）?「」＂、[]{}#%-*+=_|~＜＞$?^?‘@#$%^&*()_+‘"]; // 过滤字符串的特殊字符 NSString *newString = [string stringByTrimmingCharactersInSet:set]; return newString;}7. 让ios应用直接退出
+ (void)backOutApp { UIWindow *window = [[UIApplication sharedApplication].delegate window]; [UIView animateWithDuration:1.0f animations:^{ window.alpha = 0; } completion:^(BOOL finished) { exit(0); }];}8. NSArray 快速求总和、最大值、最小值、平均值
+ (NSString *)caculateArray:(NSArray *)array{ CGFloat sum = [[array valueForKeyPath:@"@sum.floatValue"] floatValue]; CGFloat avg = [[array valueForKeyPath:@"@avg.floatValue"] floatValue]; CGFloat max =[[array valueForKeyPath:@"@max.floatValue"] floatValue]; CGFloat min =[[array valueForKeyPath:@"@min.floatValue"] floatValue]; NSLog(@"%fn%fn%fn%f",sum,avg,max,min); return [NSString stringWithFormat:@"%f",sum];}9. 验证身份证
+ (BOOL)checkIdentityCardNo:(NSString*)value { value = [value stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; NSInteger length =0; if (!value) { return NO; }else { length = value.length; if (length !=15 && length !=18) { return NO; } } // 省份代码 NSArray *areasArray [email protected][@"11",@"12", @"13",@"14", @"15",@"21", @"22",@"23", @"31",@"32", @"33",@"34", @"35",@"36", @"37",@"41", @"42",@"43", @"44",@"45", @"46",@"50", @"51",@"52", @"53",@"54", @"61",@"62", @"63",@"64", @"65",@"71", @"81",@"82", @"91"]; NSString *valueStart2 = [value substringToIndex:2]; BOOL areaFlag =NO; for (NSString *areaCode in areasArray) { if ([areaCode isEqualToString:valueStart2]) { areaFlag =YES; break; } } if (!areaFlag) { return false; } NSRegularExpression *regularExpression; NSUInteger numberofMatch; NSInteger year =0; switch (length) { case 15: year = [[value substringWithRange:NSMakeRange(6,2)] integerValue] +1900; if (year %4 ==0 || (year 0 ==0 && year %4 ==0)) { regularExpression = [[NSRegularExpression alloc]initWithPattern:@"^[1-9][0-9]{5}[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|[1-2][0-9]))[0-9]{3}$" options:NSRegularExpressionCaseInsensitive error:nil];//测试出生日期的合法性 }else { regularExpression = [[NSRegularExpression alloc]initWithPattern:@"^[1-9][0-9]{5}[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|1[0-9]|2[0-8]))[0-9]{3}$" options:NSRegularExpressionCaseInsensitive error:nil];//测试出生日期的合法性 } numberofMatch = [regularExpression numberOfMatchesInString:value options:NSMatchingReportProgress range:NSMakeRange(0, value.length)]; if(numberofMatch >0) { return YES; }else { return NO; } case 18: year = [value substringWithRange:NSMakeRange(6,4)].intValue; if (year %4 ==0 || (year 0 ==0 && year %4 ==0)) { regularExpression = [[NSRegularExpression alloc]initWithPattern:@"^[1-9][0-9]{5}19[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|[1-2][0-9]))[0-9]{3}[0-9Xx]$"options:NSRegularExpressionCaseInsensitive error:nil];//测试出生日期的合法性 }else { regularExpression = [[NSRegularExpression alloc]initWithPattern:@"^[1-9][0-9]{5}19[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|1[0-9]|2[0-8]))[0-9]{3}[0-9Xx]$" options:NSRegularExpressionCaseInsensitive error:nil];//测试出生日期的合法性 } numberofMatch = [regularExpression numberOfMatchesInString:value options:NSMatchingReportProgress range:NSMakeRange(0, value.length)]; if(numberofMatch >0) { int S = ([value substringWithRange:NSMakeRange(0,1)].intValue + [value substringWithRange:NSMakeRange(10,1)].intValue) *7 + ([value substringWithRange:NSMakeRange(1,1)].intValue + [value substringWithRange:NSMakeRange(11,1)].intValue) *9 + ([value substringWithRange:NSMakeRange(2,1)].intValue + [value substringWithRange:NSMakeRange(12,1)].intValue) *10 + ([value substringWithRange:NSMakeRange(3,1)].intValue + [value substringWithRange:NSMakeRange(13,1)].intValue) *5 + ([value substringWithRange:NSMakeRange(4,1)].intValue + [value substringWithRange:NSMakeRange(14,1)].intValue) *8 + ([value substringWithRange:NSMakeRange(5,1)].intValue + [value substringWithRange:NSMakeRange(15,1)].intValue) *4 + ([value substringWithRange:NSMakeRange(6,1)].intValue + [value substringWithRange:NSMakeRange(16,1)].intValue) *2 + [value substringWithRange:NSMakeRange(7,1)].intValue *1 + [value substringWithRange:NSMakeRange(8,1)].intValue *6 + [value substringWithRange:NSMakeRange(9,1)].intValue *3; int Y = S ; NSString *M [email protected]"F"; NSString *JYM [email protected]"10X98765432"; M = [JYM substringWithRange:NSMakeRange(Y,1)];// 判断校验位 if ([M isEqualToString:[value substringWithRange:NSMakeRange(17,1)]]) { return YES;// 检测ID的校验位 }else { return NO; } }else { return NO; } default: return false; }}10. 设置Label里的字符有不同的颜色//可根据自己的需求进行增删改
