问题描述
详细的场景是这样的:
我正在使用循环创建 10 个按钮并将标签设置为 0-9.在点击每个按钮时，我正在调用一个 UIPickerView，我在其中从不同的数组加载数据.直到这里我得到了预期的结果.但我希望从 pickerView 中选择的行应该设置为相应按钮的标题.
I am creating 10 buttons using a loop and setting the tags from 0-9. On tap of each button I am calling a UIPickerView in which I am loading data from different arrays. Till here I am getting the expected results. But I want the selected row from the pickerView should set as the title of respective button.
我尝试过的方式 - 我将选定的行存储在 pickerViewDelegate 方法中的 NSString 中，并尝试像 setTitle 一样:
Way I tried - I stored the selected row in a NSString in the pickerViewDelegate method and trying to setTitle like :
[myButton setTitle:selectedString forState:UIControlStateNormal]
但它没有反映在任何按钮中.
but it's not reflecting in any of the buttons.
知道我错过了什么吗?
谢谢
推荐答案
你的 UIButton 点击动作，
- (IBAction) buttonTaped:(UITapGestureRecognizer *)sender
{
myButton=(UIButton *) sender.view; //It will make reference to tapped button,
//Once you've this, in your picker delegate, you can set title for it
//myButton should be declare in your controller's header file.
}
或
- (IBAction) buttonTaped:(UIButton *)sender
{
myButton=(UIButton *) sender;
}
您的 UIPickerView 委托
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
[myButton setTitle:[yourArray objectAtIndex:row] forState:UIControlStateNormal];
}
