UITextField右对齐iOS 7

Question

我有一个问题,当在iOS7上右对齐UITextField时,当用户键入"Space"时,它不会马上出现.如果我输入另一个字符,则会出现空格.

在iOS 6中确实没有发生

有人知道怎么修这个东西吗？

Answer 1

-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
    if (range.location == textField.text.length && [string isEqualToString:@" "]) {
        // ignore replacement string and add your own
        textField.text = [textField.text stringByAppendingString:@"\u00a0"];
        return NO;
    }
    // for all other cases, proceed with replacement
    return YES;
}

从文本中删除代码

self.txtFirstName.text = [self.txtFirstName.text stringByReplacingOccurrencesOfString:@"\u00a0" withString:@" "];
