iOSでの電話番号のフォーマット
ユーザーがデータを入力するテキストフィールドがあります。電話番号フィールドです。ユーザーが1234567890と入力した場合、ユーザーが入力するときに(123)-(456)-7890として表示されるようにします。これはどのように可能ですか？

これはより明確に感じられ、不要な文字の削除をよりうまく処理します。 1（###）### ‑ ####または（###）### ‑ ####の正しいフォーマット

NSString *decimalString = [components componentsJoinedByString:@""];
NSUInteger length = decimalString.length;
BOOL hasLeadingOne = length > 0 && [decimalString characterAtIndex:0] == '1';

以下のコードは、私が通常使用するものです。形式は異なりますが、画像が表示されます。これにより、「123df＃$ @ $ gdfg45- + 678dfg901」などの入力と「1（234）567-8901」が出力されます。

電話番号用のカスタムNSFormatterサブクラスをここに記述しました： https://github.com/edgecase/PhoneNumberFormatter
他のNSFormatterサブクラスと同様に使用できます。
最初の答えをどうもありがとう。しかし、そのメソッド-(int)getLength:(NSString*)mobileNumberは役に立たないと思います。以下のようなものを試すことができます：
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{
int length = [[self formatNumber:[textField text]] length];
if (length == 10) {
if(range.length == 0) {
return NO;
}
}
if (length == 3) {
NSString *num = [self formatNumber:[textField text]];
textField.text = [NSString stringWithFormat:@"(%@) ",num];
if (range.length > 0) {
[textField setText:[NSString stringWithFormat:@"%@",[num substringToIndex:3]]];
}
}
else if (length == 6) {
NSString *num = [self formatNumber:[textField text]];
[textField setText:[NSString stringWithFormat:@"(%@) %@-",[num substringToIndex:3],[num substringFromIndex:3]]];
if (range.length > 0) {
[textField setText:[NSString stringWithFormat:@"(%@) %@",[num substringToIndex:3],[num substringFromIndex:3]]];
}
}
return YES;
}
- (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;
}

C++、JavaおよびJavaScript実装。
たぶん、あなたはこの簡単な方法を使うことができます：
+ (NSString*) formatPhoneNumber:(NSString *)phoneNumber codeLength:(int) code segmentLength:(int) segment
{
NSString* result = @"";
int length = [phoneNumber length];
NSString* firstSegment = @"";
NSString* restSegment = @"";
for (int i=0; i<length; i++) {
char c = [phoneNumber characterAtIndex:i];
if(i < code)
firstSegment = [firstSegment stringByAppendingFormat:@"%c", c];
else
{
restSegment = [restSegment stringByAppendingFormat:@"%c", c];
int threshold = (i - code) + 1;
if((threshold % segment == 0) && (threshold > 0) && !(threshold > length))
restSegment = [restSegment stringByAppendingFormat:@"%c", '-'];
}
}
result = [result stringByAppendingFormat:@"%@-%@", firstSegment, restSegment];
return result;
}
上記のメソッドがContactクラスにあると仮定して、次のようなメソッドを使用します。
NSString* phoneNumber = @"085755023455";
NSString* formattedNumber = [Contact formatPhoneNumber:phoneNumber codeLength:3 segmentLength:4];
それは次のような結果になります：
085-7550-2345-5

最初に、UITextFieldDelegateを.hファイルに追加し、UITextFieldファイルのnibを委任します。
次に、このコードを.mファイルに追加します。

REFormattedNumberField がおそらく最適です。希望する形式を指定してください。
- すべての数字以外の文字を削除します
- 7桁が残っている場合、123-4567
- 10桁の場合、（123）456-7890
それ以外の場合は、3つのグループ。グループのサイズを調整するには、substrsizeに割り当てられた値を変更します
-(NSString*)formatPhone:(NSString*)phone { NSString *formattedNumber = [[phone componentsSeparatedByCharactersInSet: [[NSCharacterSet decimalDigitCharacterSet] invertedSet]] componentsJoinedByString:@""]; int substrSize = 3; NSMutableArray *t = [[NSMutableArray alloc] initWithCapacity:formattedNumber.length / substrSize + 1]; switch (formattedNumber.length) { case 7: formattedNumber = [NSString stringWithFormat:@"%@-%@", [formattedNumber substringToIndex:3], [formattedNumber substringFromIndex:3]]; break; case 10: formattedNumber = [NSString stringWithFormat:@"(%@) %@-%@", [formattedNumber substringToIndex:3], [formattedNumber substringWithRange:NSMakeRange(3, 3)], [formattedNumber substringFromIndex:6]]; break; default: for (int i = 0; i < formattedNumber.length / substrSize; i++) { [t addObject:[formattedNumber substringWithRange:NSMakeRange(i * substrSize, substrSize)]]; } if (formattedNumber.length % substrSize) { [t addObject:[formattedNumber substringFromIndex:(substrSize * t.count)]]; } formattedNumber = [t componentsJoinedByString:@" "]; break; } return formattedNumber; }
NSString *str=@"[+]+91[0-9]{10}";
NSPredicate *no=[NSPredicate predicateWithFormat:@"SELF MATCHES %@",str];
if([no evaluateWithObject:txtMobileno.text]==NO
{
UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Warning" message:@"Please Enter correct contact no." delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil];
[alert show];
[alert release];
}
したがって、このメソッドは（xxx）xxx-xxxx ...の形式になります。
