判断是否为URL地址
- (BOOL)isTrueUrl {
NSString *pattern = @"http(s)?://([\\w-]+\\.)+[\\w-]+(/[\\w- ./?%&=]*)?";
NSRegularExpression *regex = [[NSRegularExpression alloc] initWithPattern:pattern options:0 error:nil];
NSArray *regexArray = [regex matchesInString:self options:0 range:NSMakeRange(0, self.length)];
if (regexArray.count > 0) return YES; else return NO;
}
判断是否为手机号----简单判断
- (BOOL)isPhoneNumber {
NSString *reg = @"^(((13[0-9]{1})|(15[0-9]{1})|(18[0-9]{1})|(19[0-9]{1})|(17[0-9]{1})|(14[4-7]{1}))+\\d{8})$";
NSPredicate *regextestcm = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", reg];
return [regextestcm evaluateWithObject:self];
}
判断密码是否输入正确（6-16位）

NSPredicate *pred = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", regex];
BOOL isMatch = [pred evaluateWithObject:self];
return isMatch;
}
手机号中间四位变星
- (NSString *)phoneNumberHiddenCenter {
if (![self isPhoneNumber]) {
return nil;
}
NSString *startStr = [self substringWithRange:NSMakeRange(0, 3)];
NSString *endStr = [self substringWithRange:NSMakeRange(self.length-4, 4)];
NSString *hiddenStr = [NSString stringWithFormat:@"%@****%@",startStr,endStr];
return hiddenStr;
