validation电话号码ios

我需要validation一个国际电话号码。

我知道很难validation国际电话号码，所以我要保持简单：

+或00然后6-14数字

我目前的代码使用正则expression式不工作，由于某些原因，我不能工作。 它只是说，它不能打开正则expression式和崩溃。

这是我现在的代码：

 NSString *phoneRegex = @"^[\+(00)][0-9]{6,14}$"; NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", phoneRegex]; BOOL phoneValidates = [phoneTest evaluateWithObject:phoneNumber]; 

我哪里错了？

谢谢！

Answer 1

 NSString *phoneRegex = @"^((\\+)|(00))[0-9]{6,14}$"; 

这种方式好一点。 如果您转义“\”，您的代码也可以工作。

Answer 2

复制和粘贴方法来validation电话号码：

 - (BOOL)validatePhone:(NSString *)phoneNumber { NSString *phoneRegex = @"^((\\+)|(00))[0-9]{6,14}$"; NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", phoneRegex]; return [phoneTest evaluateWithObject:phoneNumber]; } 

或者用于validation电话号码的开源库

那么这取决于你想成为多严格，看起来不像这个正则expression式特别严格。 这个正则expression式说：

从行匹配的开头开始，一个+（或者可能是1或者0），这似乎是模棱两可的（但可能不取决于实现），因为捕获圆括号:(）分开了+和？ 可能错位：匹配任何数字0-9 1或0次6-14次然后一个数字0-9然后行结束。 你也注意到任何反斜杠都必须加倍… @“\ b”为单词边界。 你可能想尝试像…

 @"\\b[\\d]{3}\\-[\\d]{3}\\-[\\d]{4}\\b" would I think match your example, but it wouldn't match (555) 555 - 5555 or 555.555.5555 or [phone]

txtlpmobile.text是string（移动不，你会进入）

  int length = [self getLength:txtLpMobile.text]; if(length == 10) { if(range.length == 0) return NO; } if(length == 3){ NSString *num = [self formatNumber:txtLpMobile.text]; txtLpMobile.text = [NSString stringWithFormat:@"(%@) ",num]; if(range.length > 0) { txtLpMobile.text = [NSString stringWithFormat:@"%@",[num substringToIndex:3]]; } } else if(length == 6) { NSString *num = [self formatNumber:txtLpMobile.text]; txtLpMobile.text = [NSString stringWithFormat:@"(%@) %@-",[num substringToIndex:3],[num substringFromIndex:3]]; if(range.length > 0) { txtLpMobile.text = [NSString stringWithFormat:@"(%@) %@",[num substringToIndex:3],[num substringFromIndex:3]]; } } NSUInteger newLength; newLength = [txtLpMobile.text length] + [string length] - range.length; NSCharacterSet *cs = [[NSCharacterSet characterSetWithCharactersInString:NUMBERS_ONLY] invertedSet]; NSString *filtered = [[string componentsSeparatedByCharactersInSet:cs] componentsJoinedByString:@""]; return (([string isEqualToString:filtered])&&(newLength <= CHARACTER_LIMIT)); 

用于格式化数字

 -(NSString*)formatNumber:(NSString*)mobileNumber { mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"(" withString:@""]; mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@")" withString:@""]; mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@" " withString:@""]; mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"-" withString:@""]; mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"+" withString:@""]; int length = [mobileNumber length]; if(length > 10) { mobileNumber = [mobileNumber substringFromIndex: length-10]; } return mobileNumber; } 

为了获得长度

 -(int)getLength:(NSString*)mobileNumber { mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"(" withString:@""]; mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@")" withString:@""]; mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@" " withString:@""]; mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"-" withString:@""]; mobileNumber = [mobileNumber stringByReplacingOccurrencesOfString:@"+" withString:@""]; int length = [mobileNumber length]; return length; } 

Answer 5

validation电话号码的唯一好方法是使用Google的惊人LibPhoneNumber 。 有一个iOS端口，或者你可以在隐藏的UIWebView运行JavaScript实现。

（我已经做了后几年，当时他们还没有iOS的端口，作品像一个魅力，即使在旧的iPhone上也非常快。

简单的方法来validation电话号码和密码的限制，只需按照以下过程。

 if ((self.mobileTxtFld.text.length < 10 )) { [_mobileTxtFld becomeFirstResponder]; } else if ((self.passwordTxtFld.text.length < kPasswordCharacterMinLimit) || (self.passwordTxtFld.text.length > kPasswordCharacterMaxLimit)) { // show alert } 

之后，你可以实现textfiled委托方法“shouldChangeCharactersInRange”中只写这个代码

 if (textField == _mobileTxtFld) { if([string rangeOfCharacterFromSet:ALLOWED_NUMBERS].location == NSNotFound){ NSUInteger newLength = [textField.text length] + [string length] - range.length; if(newLength > kMobileNumberLimit - 1){ if(textField.text.length != kMobileNumberLimit){ textField.text = [NSString stringWithFormat:@"%@%@",textField.text,string]; } [textField resignFirstResponder]; return NO; } else{ return YES; } } else{ return NO; } } return YES; 

这里是ALLOWED_NUMBERS和kMobileNumberLimit

 #define kMobileNumberLimit 10 #define ALLOWED_NUMBERS [[NSCharacterSet decimalDigitCharacterSet] invertedSet] #define minLimit 6 #define maxLimit 17 

Answer 7

 -(int)findLength:(NSString*)phoneNumber { phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:@"(" withString:@""]; phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:@")" withString:@""]; phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:@" " withString:@""]; phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:@"-" withString:@""]; phoneNumber = [phoneNumber stringByReplacingOccurrencesOfString:@"+" withString:@""]; int length = [phoneNumber length]; return length;
