一些經常使用的正則表達式（手機號、身份證號、郵箱等判斷）
1. 判斷手機號碼格式是否正確，利用正則表達式驗證git
+ (BOOL)isMobileNumber:(NSString *)mobileNum
{
if
(mobileNum.length != 11)
{
return
NO;
}
/**
* 手機號碼:
* 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]
* 移動號段: 134,135,136,137,138,139,150,151,152,157,158,159,182,183,184,187,188,147,178,1705
* 聯通號段: 130,131,132,155,156,185,186,145,176,1709
* 電信號段: 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}$"
;
/**
* 中國移動：China Mobile
* 134,135,136,137,138,139,150,151,152,157,158,159,182,183,184,187,188,147,178,1705
*/
NSString *CM = @
"(^1(3[4-9]|4[7]|5[0-27-9]|7[8]|8[2-478])\d{8}$)|(^1705\d{7}$)"
;
/**
* 中國聯通：China Unicom
* 130,131,132,155,156,185,186,145,176,1709
*/
NSString *CU = @
"(^1(3[0-2]|4[5]|5[56]|7[6]|8[56])\d{8}$)|(^1709\d{7}$)"
;
/**
* 中國電信：China Telecom
* 133,153,180,181,189,177,1700
*/
NSString *CT = @
"(^1(33|53|77|8[019])\d{8}$)|(^1700\d{7}$)"
;
NSPredicate *regextestmobile = [NSPredicate predicateWithFormat:@
"SELF MATCHES %@"
, MOBILE];
NSPredicate *regextestcm = [NSPredicate predicateWithFormat:@
"SELF MATCHES %@"
, CM];
NSPredicate *regextestcu = [NSPredicate predicateWithFormat:@
"SELF MATCHES %@"
, CU];
NSPredicate *regextestct = [NSPredicate predicateWithFormat:@
"SELF MATCHES %@"
, CT];
if
(([regextestmobile evaluateWithObject:mobileNum] == YES)
|| ([regextestcm evaluateWithObject:mobileNum] == YES)
|| ([regextestct evaluateWithObject:mobileNum] == YES)
|| ([regextestcu evaluateWithObject:mobileNum] == YES))
{
return
YES;
}
else
{
return
NO;
}
}
2. 判斷郵箱格式是否正確，利用正則表達式驗證正則表達式
+ (BOOL)isAvailableEmail:(NSString *)email
{
NSString *emailRegex = @
"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}"
;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@
"SELF MATCHES %@"
, emailRegex];
return
[emailTest evaluateWithObject:email];
}
3. 判斷字符串中是否含有空格測試
+ (BOOL)isHaveSpaceInString:(NSString *)string{
NSRange _range = [string rangeOfString:@" "];
if (_range.location != NSNotFound) {
return YES;
}else {
return NO;
}
}
4. 判斷字符串中是否含有中文lua
+ (BOOL)isHaveChineseInString:(NSString *)string
{
for(NSInteger i = 0; i < [string length]; i++){
int a = [string characterAtIndex:i];
if (a > 0x4e00 && a < 0x9fff) {
return YES;
}
}
return NO;
}
5. 判斷字符串是否所有爲數字spa
+ (BOOL)isAllNum:(NSString *)string
{
unichar c;
for (int i=0; i<string.length; i++) { c="[string characterAtIndex:i];" if (!isdigit(c)) {="" return no;="" }="" }="" return yes;="" }<="" pre=""><p>判斷是不是純數字</p><pre class="brush:js;toolbar:false">+ (BOOL)isPureInteger:(NSString *)str {
NSScanner *scanner = [NSScanner scannerWithString:str];
NSInteger val;
return [scanner scanInteger:&val] && [scanner isAtEnd];
}
6. 過濾一些特殊字符
+ (NSString *)filterSpecialWithString:(NSString *)string
{
// 定義一個特殊字符的集合
NSCharacterSet *set = [NSCharacterSet characterSetWithCharactersInString:
@"@／：；: ;（）?「」＂、[]{}#%-*+=_|~＜＞$?^?'@#$%^&*()_+'"];
// 過濾字符串的特殊字符
NSString *newString = [string stringByTrimmingCharactersInSet:set];
return newString;
}
7. 讓iOS應用直接退出
+ (void)backOutApp {
UIWindow *window = [[UIApplication sharedApplication].delegate window];
[UIView animateWithDuration:1.0f animations:^{
window.alpha = 0;
} completion:^(BOOL finished) {
exit(0);
}];
}
8. NSArray 快速求總和、最大值、最小值、平均值
+ (NSString *)caculateArray:(NSArray *)array
{
CGFloat sum = [[array valueForKeyPath:@"@sum.floatValue"] floatValue];
CGFloat avg = [[array valueForKeyPath:@"@avg.floatValue"] floatValue];
CGFloat max =[[array valueForKeyPath:@"@max.floatValue"] floatValue];
CGFloat min =[[array valueForKeyPath:@"@min.floatValue"] floatValue];
NSLog(@"%fn%fn%fn%f",sum,avg,max,min);
return [NSString stringWithFormat:@"%f",sum];
}
9. 驗證身份證
+ (BOOL)checkIdentityCardNo:(NSString*)value {
value = [value stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
NSInteger length =0;
if (!value) {
return NO;
}else {
length = value.length;
if (length !=15 && length !=18) {
return NO;
}
}
// 省份代碼
NSArray *areasArray =@[@"11",@"12", @"13",@"14", @"15",@"21", @"22",@"23", @"31",@"32", @"33",@"34", @"35",@"36", @"37",@"41", @"42",@"43", @"44",@"45", @"46",@"50", @"51",@"52", @"53",@"54", @"61",@"62", @"63",@"64", @"65",@"71", @"81",@"82", @"91"];
NSString *valueStart2 = [value substringToIndex:2];
BOOL areaFlag =NO;
for (NSString *areaCode in areasArray) {
if ([areaCode isEqualToString:valueStart2]) {
areaFlag =YES;
break;
}
}
if (!areaFlag) {
return false;
}
NSRegularExpression *regularExpression;
NSUInteger numberofMatch;
NSInteger year =0;
switch (length) {
case 15:
year = [[value substringWithRange:NSMakeRange(6,2)] integerValue] +1900;
if (year %4 ==0 || (year 0 ==0 && year %4 ==0)) {
regularExpression = [[NSRegularExpression alloc]initWithPattern:@"^[1-9][0-9]{5}[0-9]{2}((01|03|05|07|08|10|12)(0[1-9]|[1-2][0-9]|3[0-1])|(04|06|09|11)(0[1-9]|[1-2][0-9]|30)|02(0[1-9]|[1-2][0-9]))[0-9]{3}$"
options:NSRegularExpressionCaseInsensitive

options:NSRegularExpressionCaseInsensitive
error:nil];//測試出生日期的合法性
}
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]$"

}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];//測試出生日期的合法性
}
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 =@"F";
NSString *JYM =@"10X98765432";
M = [JYM substringWithRange:NSMakeRange(Y,1)];// 判斷校驗位
if ([M isEqualToString:[value substringWithRange:NSMakeRange(17,1)]]) {
return YES;// 檢測ID的校驗位
}else {
return NO;
}
}else {
return NO;
}
default:
return false;
}
}
10. 設置Label裏的字符有不一樣的顏色
//可根據本身的需求進行增刪改
- (void)stringColorSet {
NSString*string = @"如何使得Label裏的字符有不一樣的顏色？";
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];
