ios - 从tableview单元格更新文本并刷新后关闭键盘

Question

嗨，我在customtableviewcell中有一个UILABEL和UITEXTFIELD。每次更改字符时我都需要更新UILABEL。当我更新文本字段键盘中的每个字符时，就关闭了..我什至尝试使用Notification Center。任何快速的帮助将是感激的

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    NSString *rateValue=[textField.text stringByReplacingCharactersInRange:range withString:string];

    NSCharacterSet *notAllowedChars = [[NSCharacterSet characterSetWithCharactersInString:@"1234567890"] invertedSet];

    NSString *resultString = [[rateValue componentsSeparatedByCharactersInSet:notAllowedChars] componentsJoinedByString:@""];

    [arrayRates replaceObjectAtIndex:textField.tag withObject:resultString];
    selectedTextField=textField;
    selectedTxtFieldPath = [NSIndexPath indexPathForRow:textField.tag inSection:0];
    [self.tableViewSkuVoids beginUpdates];
    [self.tableViewSkuVoids reloadRowsAtIndexPaths:@[selectedTxtFieldPath] withRowAnimation:UITableViewRowAnimationFade];
    [self.tableViewSkuVoids endUpdates];
    [[self.tableViewSkuVoids superview]  endEditing:NO];

   [[NSNotificationCenter defaultCenter] postNotificationName:@"keyboardWillShow" object:nil userInfo:nil];

   [selectedTextField becomeFirstResponder];
   return YES;
}

Answer 1

当您用
[self.tableViewSkuVoids reloadRowsAtIndexPaths:@[selectedTxtFieldPath] withRowAnimation:UITableViewRowAnimationFade];
它将为您的文本字段resignFirstResponder并关闭键盘

唯一的解决方案是手动调整单元格高度和表格内容高度https://stackoverflow.com/a/33621733/1060785
