iOS 之常用的正則表達(dá)式
在平時的開發(fā)中,我們會經(jīng)常會用到正則去判斷,下面是一些我經(jīng)常使用到的,如有不足,歡迎大家補(bǔ)充
1.創(chuàng)建一個公共的類
//數(shù)字
+ (BOOL) validateNumber:(NSString*)number;
//金額
+ (BOOL) validateMoney:(NSString*)money;
//郵箱
+ (BOOL) validateEmail:(NSString *)email;
//手機(jī)號碼驗證
+ (BOOL) validateMobile:(NSString *)mobile;
//車牌號驗證
+ (BOOL) validateCarNo:(NSString *)carNo;
//車型
+ (BOOL) validateCarType:(NSString *)CarType;
//用戶名
+ (BOOL) validateUserName:(NSString *)name;
//密碼
+ (BOOL) validatePassword:(NSString *)passWord;
//昵稱
+ (BOOL) validateNickname:(NSString *)nickname;
//身份證號
+ (BOOL) validateIdentityCard: (NSString *)identityCard;
實現(xiàn)方法?
+ (BOOL) validateMoney:(NSString*)money{
NSString *moneyRegex = @"^[0-9]+(.[0-9]{2})?$";
NSPredicate *moneyTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", moneyRegex];
return [moneyTest evaluateWithObject:money];
}
//數(shù)字
+ (BOOL) validateNumber:(NSString*)number
{
BOOL res = YES;
NSCharacterSet* tmpSet = [NSCharacterSet characterSetWithCharactersInString:@"0123456789"];
int i = 0;
while (i < number.length) {
NSString * string = [number substringWithRange:NSMakeRange(i, 1)];
NSRange range = [string rangeOfCharacterFromSet:tmpSet];
if (range.length == 0) {
res = NO;
break;
}
i++;
}
return res;
}
//郵箱
+ (BOOL) validateEmail:(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];
}
//手機(jī)號碼驗證
+ (BOOL) validateMobile:(NSString *)mobile
{
//手機(jī)號以13钝满， 15，18開頭福压，八個 \d 數(shù)字字符
//2015/08/25 添加14扼倘，17開頭
