我正在创建一个客户。选择一个帐户并且该帐户通过（通过segue）。想知道它是如何做到的。obs ** 数据传递是用户选择的选择器的数组（帐户）。
这将返回选择器视图：
-(NSString*)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
ACAccount *acct = [arrayOfAccounts objectAtIndex:row];
return [acct username];
}
必须将用户选择的选项（数组）传递给另一个视图以用作帐户（Twitter）
我设法用 TableView 做了一次（但我认为界面很糟糕）并决定制作pickerview。问题仅在于传递此数据（如下），不等于 tableview
Are you using a Segue to pass the data to the next view? i think that would be the best way to do that. When passing the data from the pickerview, in your segue you can do this
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
// Make sure your segue name in storyboard is the same as this line
if ([[segue identifier] isEqualToString:@"moreinfosegue"])
{
// Get reference to the destination view controller
NextViewController *nextViewC = [segue destinationViewController];
// Pass any objects to the view controller here, like...
ACAccount *acct = [self.arrayOfAccounts objectAtIndex:[_yourPickerView selectedRowInComponent:0]];
[nextViewC setACAccountValueInOtherView:acct];
}
}
Just remember that the selectedRowInComponent is set to whatever component you are taking it from the UIPickerView.
I hope this helps.
我希望我能理解你，你的描述/拼写有点模糊。
您需要实现此委托方法：
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
我不建议在选择器视图上选择时切换视图，如果您使用按钮执行 segue 会更好。您可以将选择保存在私有属性中，并使用它prepareForSegue:来将其传递给另一个视图控制器。
