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}$";    /**     * 中国移动:China Mobile     * 134,135,136,137,138,139,150,151,152,157,158,159,182,183,184,187,188,147,178,1705     */    NSString *CM = @"(^1(3[4-9]|4[7]|5[0-27-9]|7[8]|8[2-478])d{8}$)|(^1705d{7}$)";    /**     * 中国联通:China Unicom     * 130,131,132,155,156,185,186,145,176,1709     */    NSString *CU = @"(^1(3[0-2]|4[5]|5[56]|7[6]|8[56])d{8}$)|(^1709d{7}$)";    /**     * 中国电信:China Telecom     * 133,153,180,181,189,177,1700     */    NSString *CT = @"(^1(33|53|77|8[019])d{8}$)|(^1700d{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{    NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+.[A-Za-z]{2,4}";    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判断是否是纯数字[code=js]+ (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 似乎只能去除头尾的特殊字符(不准)

+ (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(本人试过,还挺准的)

+ (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 =@[@"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;

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- (void)stringColorSet {    NSString*string = @"如何使得Label里的字符有不同的颜色?";    NSRange range = [string rangeOfString: @"Label"];    NSMutableAttributedString*attribute = [[NSMutableAttributedString alloc] initWithString: string];    [attribute addAttributes: @{NSForegroundColorAttributeName: [UIColor redColor]}range: range];    [attribute addAttributes: @{NSForegroundColorAttributeName: [UIColor greenColor]}range: NSMakeRange(0, range.location)];    [attribute addAttributes: @{NSForegroundColorAttributeName: [UIColor cyanColor]}range: NSMakeRange(range.location+ range.length, 5)];    UILabel *label = [[UILabel alloc] initWithFrame: CGRectMake(0.0f, 100.0f, 320.0f, 100.0f)];    [label setText: string];    [label setAttributedText: attribute];}
