Question

我有两个UIPickerViews从数组中提取数据虽然我似乎无法单独编程。这是我用于UIPickerViews的代码：

-(NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
    return [treatments count];
}

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
    return 1;
}

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
      return[[treatments objectAtIndex:row]valueForKey:@"treatmentName"];
}

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
    _buttonText.text = [[treatments objectAtIndex:row]valueForKey:@"treatmentName"];
    if (![_buttonText.text isEqual: @"Pick a Treatment Name"]) {
        _buttonText.textColor = [UIColor blackColor];
    }
}

-(NSInteger)nursePicker:(UIPickerView *)nursePicker numberOfRowsInComponent:(NSInteger)component {
    return [nurses count];
}

- (NSString *)nursePicker:(UIPickerView *)nursePicker titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
    return[[nurses objectAtIndex:row]valueForKey:@"nurseName"];
}

当我运行代码时，选择器显示相同的数据

您应该使用BOOL来检查数据。创建一个名为treatment的BOOL，当第一个选择器可用时，将BOOL设置为YES，当第二个选择器可用时，将BOOL设置为NO。然后检查你的方法，看看哪个选择器是他们的，并放入数据。

@interface NotesViewController ()
{
    BOOL treatment; 
}

- (void)firstPickerComesUP
{
    treatment = YES;
} 

- (void)secondPickerComesUP
{
    treatment = NO;
}

设置多个UIPickerView的数据
