我需要验证国际电话号码。
我知道验证国际电话号码很困难，所以我将保持简单：
+或 00 然后 6-14 个数字
由于某种我无法解决的原因，我当前使用正则表达式的代码无法正常工作。它只是说它无法打开正则表达式并崩溃。
这是我当前的代码：
NSString *phoneRegex = @"^[\+(00)][0-9]{6,14}$";
NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", phoneRegex];
BOOL phoneValidates = [phoneTest evaluateWithObject:phoneNumber];
我哪里错了？
谢谢！
NSString *phoneRegex = @"^((\\+)|(00))[0-9]{6,14}$";
这种方式好一点。如果您转义“\”，您的代码也可以正常工作。
复制和粘贴方法来验证电话号码：
- (BOOL)validatePhone:(NSString *)phoneNumber
{
NSString *phoneRegex = @"^((\\+)|(00))[0-9]{6,14}$";
NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", phoneRegex];
return [phoneTest evaluateWithObject:phoneNumber];
}
或用于验证电话号码的开源库
好吧，这取决于您想要的严格程度，这个正则表达式似乎并不是特别严格。这个正则表达式说：
从行首开始匹配一个 +（或者可能是 1 或 0），这似乎模棱两可（但可能不取决于实现），因为捕获括号：() 打破了 + 和 ? 可能放错了位置：匹配任何数字 0-9 1 或 0 次 6-14 次，然后是一个数字 0-9，然后是行尾。您还注意到，任何反斜杠都必须加倍...... @"\b" 用于单词边界。您可能想尝试类似...
@"\\b[\\d]{3}\\-[\\d]{3}\\-[\\d]{4}\\b"
would I think match your example, but it wouldn't match
(555) 555 - 5555 or
555.555.5555 or
+44 1865 55555
NSString *phoneRegex = @"^((\\+)|(00))[0-9]{6,14}|[0-9]{6,14}$";
这是经过测试的 RegularExpression 这将接受带有国家代码或不带国家代码
txtlpmobile.text 是字符串（手机不输入）
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;
}
验证电话号码的唯一好方法是使用Google 惊人的 LibPhoneNumber。有一个 iOS 端口，或者您可以在隐藏的UIWebView.
（几年前我已经完成了后者，当时他们还没有 iOS 端口。就像一个魅力，即使在旧 iPhone 上也非常快。）
验证电话号码和密码限制的简单方法，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，您可以实现文本文件委托方法“shouldChangeCharactersInRange”，只需编写此代码
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 ALLOWED_NUMBERS 和 kMobileNumberLimit 是
#define kMobileNumberLimit 10
#define ALLOWED_NUMBERS [[NSCharacterSet decimalDigitCharacterSet] invertedSet]
#define minLimit 6
#define maxLimit 17
在迅速 4 -
func ValidateMobileNumber(txtFeid : UITextField, strChk : String, range: NSRange) -> Bool {
if txtFeid.text!.count >= 10 {
return false
}
let formatePre = "^((\\+)|(00))[0-9]{6,14}$"
let resultPredicate : NSPredicate = NSPredicate(format: "SELF MATCHES %@",formatePre)
return resultPredicate.evaluate(with: strChk)
}
-(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;
}
