我知道使用 UIDatePicker，您可以使用以下内容:

NSDate *myDate = picker.date;

但我在 View 中使用了 UIPickerView。我怎样才能同样获得选定的值？还是我必须设置 didSelectRow 类型的方法才能做到这一点？

更新: 此代码适用于具有 1 个组件的选择器:

NSInteger row;
NSString *weightSelected;

row = [repPicker selectedRowInComponent:0];
weightSelected = [pickerArray objectAtIndex:row];

我用 2 个组件为我的选择器厌倦了这段代码，但它是卡住的:

NSInteger row1, row2;
NSString *weightSelected1;
NSString *weightSelected2;

row1 = [repPicker selectedRowInComponent:0];
row2 = [repPicker selectedRowInComponent:1];
weightSelected1 = [pickerArray objectAtIndex:row1];
weightSelected2 = [pickerArray objectAtIndex:row2];
NSString *weightSelected = [NSString stringWithFormat:@"%@.%@", weightSelected1, weightSelected2];

最佳答案

您可以通过以下方式获取:

NSInteger row;
NSArray *repeatPickerData;
UIPickerView *repeatPickerView;

row = [repeatPickerView selectedRowInComponent:0];
self.strPrintRepeat = [repeatPickerData objectAtIndex:row];
