我的 iphone 上有一个表单屏幕，我正在尝试复制 Iphone 联系人应用程序，它将自动完成以下电话号码格式：(233)323-2323。
我非常接近我能够在文本字段中看到格式更新，但其他 4 个文本字段现在不起作用。我无法编辑它们。我将其缩小到 shouldchangecharactersinrange 函数。
请看下面的代码。
谢谢。
quick look at the method:
- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{
if(([textField tag] == 2)){
int length = [self getLength:textField.text];
//NSLog(@"Length = %d ",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.text = [NSString stringWithFormat:@"%@",[num substringToIndex:3]];
}
else if(length == 6)
{
NSString *num = [self formatNumber:textField.text];
//NSLog(@"%@",[num substringToIndex:3]);
//NSLog(@"%@",[num substringFromIndex:3]);
textField.text = [NSString stringWithFormat:@"(%@) %@-",[num substringToIndex:3],[num substringFromIndex:3]];
if(range.length > 0)
textField.text = [NSString stringWithFormat:@"(%@) %@",[num substringToIndex:3],[num substringFromIndex:3]];
}
return YES;
}else if([textField tag] != 1){
return NO;
}
}
