Используете много видов выбора в различных листах действий?

Question

В моем приложении я использую 4 вида выбора в листе действий, в которых я могу получить определенное значение от конкретного сборщика?в котором я использовал метод, чтобы получить его., но мне нужен лучший способ получить его., PLZ, помогите мне.,

    NSLog(@"pickerView");
    return [pickerArray count];

    return [pickerArray objectAtIndex:row];
}

- (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {

    if (validateButton == 0){

        NSInteger temp = (row*5);
        minAsleepInt = temp;
        minAsleepLable.text = [NSString stringWithFormat:@"%d",temp];
    }
    else if(validateButton == 1){

        noOptInt = row+1;
        noOptLable.text = [pickerArray objectAtIndex:row];
    }

Answer 1

Как вы уже сделали, вам нужно настроить следующие методы делегата:

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
    return PICKER_COMPONENTS;
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component {
    return [self.pickerOptions count];
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
    return [self.pickerOptions objectAtIndex:row];
}

Теперь, что касается ответа на выбор каждого сборщика, я бы рекомендовал использовать EAActionSheetPicker . Он имеет следующий необязательный метод делегата, который облегчает жизнь

-(void)EAActionSheetPicker:(EAActionSheetPicker *)actionSheet
   didDismissWithSelection:(id)selection
               inTextField:(UITextField *)textField{
    // respond to your selection here
}

Вам просто нужно правильно настроить его, подключив каждый pickerView с соответствующим ответом textField. Посмотрите пример проекта в репо, чтобы понять, о чем я говорю.

Answer 2

вы можете установить тег для каждого сборщика.И получить конкретное значение из конкретного сборщика, используя значение TAG.
