iOS의 전화 번호 형식
사용자가 데이터를 입력하는 텍스트 필드가 있습니다. 전화 번호 필드입니다. 사용자가를 입력하면 사용자가 입력 1234567890할 때 표시되기를 원합니다 (123)-(456)-7890. 이것이 어떻게 가능한지?
이것은 당신을 도울 것입니다
형식 (xxx) xxx-xxxx
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string

이것은 더 명확하게 느껴지고 원하지 않는 문자를 훨씬 더 멋지게 제거합니다. 1 (###) ### ‑ #### 또는 (###) ### ‑ ####에 대해 올바른 형식

NSUInteger length = decimalString.length;
BOOL hasLeadingOne = length > 0 && [decimalString characterAtIndex:0] == '1';

아래 코드는 제가 일반적으로 사용하는 것입니다. 형식은 다르지만 그림을 얻을 수 있습니다. 이것은 '123df # $ @ $ gdfg45- + 678dfg901'과 같은 입력을 처리하고 '1 (234) 567-8901'을 출력합니다.

switch (phoneString.length) {
case 7: return [NSString stringWithFormat:@"%@-%@", [phoneString substringToIndex:3], [phoneString substringFromIndex:3]];

다른 NSFormatter 서브 클래스처럼 사용할 수 있습니다.
첫 번째 답변 감사 합니다만, 그 방법 -(int)getLength:(NSString*)mobileNumber은 쓸모가 없다고 생각 합니다. 다음과 같이 시도 할 수 있습니다.

이 간단한 방법을 사용할 수 있습니다.
+ (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];

위의 방법이 Contact클래스에 있다고 가정하면 다음과 같은 방법을 사용하십시오.
NSString* phoneNumber = @"085755023455";
NSString* formattedNumber = [Contact formatPhoneNumber:phoneNumber codeLength:3 segmentLength:4];
결과는 다음과 같습니다.
