Question

我的iPad应用程序中的UITableViewCell内部有一个UITextField。如果我输入文字，然后按下解除键盘按钮，它会保存文字，但如果我点击更改视图而不先取消键盘，则表示不保存文字。

我正在使用此代码尝试将textField作为第一响应者重新签名，但没有运气。

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    for (int it=0; it < [self.clinicalChecklist count]; ++it)
    {
        ClinicalChecklistCell *cell = (ClinicalChecklistCell *)[self.tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:it inSection:0]];
        UITouch *touch = [[event allTouches] anyObject];
        if ([cell.col1_singleEntryValue isFirstResponder] && [touch view] != cell.col1_singleEntryValue) {
            [cell.col1_singleEntryValue resignFirstResponder];
        }
        if ([cell.col2_singleEntryValue isFirstResponder] && [touch view] != cell.col2_singleEntryValue) {
            [cell.col2_singleEntryValue resignFirstResponder];
        }
        if ([cell.col1_doubleEntryValue_1 isFirstResponder] && [touch view] != cell.col1_doubleEntryValue_1) {
            [cell.col1_doubleEntryValue_1 resignFirstResponder];
        }
        if ([cell.col1_doubleEntryValue_2 isFirstResponder] && [touch view] != cell.col1_doubleEntryValue_2) {
            [cell.col1_doubleEntryValue_2 resignFirstResponder];
        }
        if ([cell.col2_doubleEntryValue_1 isFirstResponder] && [touch view] != cell.col2_doubleEntryValue_1) {
            [cell.col2_doubleEntryValue_1 resignFirstResponder];
        }
        if ([cell.col2_doubleEntryValue_2 isFirstResponder] && [touch view] != cell.col2_doubleEntryValue_2) {
            [cell.col2_doubleEntryValue_2 resignFirstResponder];
        }
        [super touchesBegan:touches withEvent:event];
    }
}

如果您只想获取UITextField的文本，

[myTextField addTarget:self action:@selector(getText) forControlEvents:UIControlEventEditingChanged];

UITextField委托不工作
