显然,此代码适用于iOS 6.顺便说一句,它在iOS 7中存在问题。
我将UIButton添加到UIPickerView中的每一行:
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view
{
UIButton *btnRow=[UIButton buttonWithType:UIButtonTypeSystem];
[btnRow addTarget:self action:@selector(touch:) forControlEvents:UIControlEventTouchUpInside];
btnRow.frame=CGRectMake(0, 0, 320, 30);
int tag= selfTextField.tag/10000 - 1;
[btnRow setTitle:[[pickerArray objectAtIndex:tag] objectAtIndex:row] forState:UIControlStateNormal];
return btnRow;
}
答案 0 :(得分:1)
您无法在选择器视图行上放置按钮。所以我在UIPickerView上面添加了一个工具栏,并在其上添加了一个条形按钮项。我使用行号通过选择器
执行所需的功能- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
....
//get the row number & Perform desired functionality
....
}
您将获得行号并使用它来执行所需的功能。
