我正在处理电话号码正则表达式，如XXX XXX-XXXX的电话文字字段，代码工作正常，但它会打扰其他文本字段，如姓名，电子邮件，我应该怎么做才能将名称正则表达式与nameTextFields分开 我写了这样的代码
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
if(textField==txtName){
if (txtName.text.length >2) {
tickFirstName.hidden = NO;
[tickFirstName setTextColor: [UIColor colorWithRed:56.0/255.0 green:234.0/255.0 blue:126.0/255.0 alpha:1]];
}
if (textField.text && textField.text.length == 0)
{
tickFirstName.hidden = YES;
}
else
{
/* what ever */
}
}
if([textField == txtPhone)
{
if ([txtPhone.text length]>0) {
int length = [txtPhone.text length];
NSLog(@"Length = %d ",length);
if([txtPhone.text length] == 12)
{
if(range.length == 0)
return NO;
}
NSString *newString = [txtPhone.text stringByReplacingCharactersInRange:range withString:string];
NSLog(@"-------------%@",string);

error:nil];
NSUInteger numberOfMatches = [regex numberOfMatchesInString:newString
options:0
range:NSMakeRange(0, [newString length])];
NSLog(@"newString::%@",newString);
if (numberOfMatches == 0)
return NO;
if(length == 3)

txtPhone.text = [NSString stringWithFormat:@"%@",num];
if(range.length > 0)
txtPhone.text = [NSString stringWithFormat:@"%@",[num substringToIndex:3]];
}
else if(length == 6)
