在不同的操作表中使用多个选择器视图？

发布于 2024-12-23 04:28:38 字数 7845 浏览 2 评论 0原文

在我的应用程序中，我在操作表中使用 4 个选取器视图，其中我如何从特定选取器获取特定值？ 其中我使用了一种方法来获取它。但是我需要一种更好的方法来获取它。请帮助我。，

-(NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component {
    NSLog(@"pickerView");
    return [pickerArray count];
}

- (NSString *)pickerView:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
    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];
    }
    else if(validateButton == 2){

        ageTypeLable.text = [pickerArray objectAtIndex:row];
    }
    else if(validateButton == 3){

        if([pickerArray objectAtIndex:row] == @"Yes"){
            sleepLessBool = YES;
        }else{

您可以为每个选择器设置一个标签。并使用标签值从特定选择器获取特定值。

you can set a Tag for each picker. And get the particular value from particular picker using the TAG value.

正如您所做的那样，您需要设置以下委托方法：

- (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];
}

现在，就响应每个选择器的选择而言，我建议使用 EAActionSheetPicker。它具有以下可选的委托方法，使生活更轻松。

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

您只需通过将每个 pickerView 与关联的响应文本字段连接起来即可正确设置它。查看存储库中的示例项目以了解我在说什么。

As you've done, you need to setup the following delegate methods:

- (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];
}

Now, as far as responding to each picker's selection, I would recommend using EAActionSheetPicker. It has the following optional delegate method that makes life easier

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

You'll just have to set it up right by hooking up each pickerView with the associated response textField. Check out the example project at the repo to see what I'm talking about.
