从dict获得价值

Question

我跟随json回应。

{
        bufferTime = 15;
        cutOffTime = "02:00";
        shiftId = 1;
        shiftTime = "07:00";
        tripType = PICKUP;
    },
        {
        bufferTime = 15;
        cutOffTime = "02:00";
        shiftId = 2;
        shiftTime = "09:00";
        tripType = PICKUP;
    },

我使用以下命令将响应存储在NSMutable数组中。

   {
        for (int i = 0; i < numberOfItems; i++) {
                        NSDictionary *dict = [res objectAtIndex:i];
                        [shiftIdArray addObject: [dict objectForKey:@"shiftId"]];
                        [shiftTimeArray addObject: [dict objectForKey:@"shiftTime"]];
                        [cutOffTimeArray addObject:[dict objectForKey:@"cutOffTime"]];
                        //NSLog(@"dict : %@",dict);
                    }
    self.dpShiftTimePicker = [[DownPicker alloc] initWithTextField:self.txtShiftTime withData:shiftTimeArray];
                    [self.dpShiftTimePicker addTarget:self
                                              action:@selector(dp_Selected2:)
                                    forControlEvents:UIControlEventValueChanged];
    }

-(void)dp_Selected2:(id)dp{
    NSString* selectedValue = [self.dpShiftTimePicker text];
    NSLog(@"selectedValue: %@",selectedValue);
}

我在我的编程器中传递了 shiftTimeArray ，这是我编程的。现在，在为例如 09:00 选择特定的 shiftTime 时，我希望得到它相应的 shiftId 和 cutOffTime < / strong>并存储在字符串中。请帮助。

试试这个 -

- (void)dp_Selected2:(id)dp
{
     NSString* selectedValue = [self.dpShiftTimePicker text];

     NSString* selectedIDValue =  [shiftIdArray objectAtIndex:[shiftTimeArray indexOfObject:selectedValue]];

     NSString* selectedCutOFFValue  = [cutOffTimeArray objectAtIndex:[shiftTimeArray indexOfObject:selectedValue]];

     NSLog(@"selectedValue: %@",selectedValue);
 }
