从Uipickerview中选择数据时，如何在Uilabel上显示字符串格式？

Question

  

嗨，我有一个选择器视图。来自Web服务的这个选择器视图来了   加载数据中。这个选择器视图是2部分。选择器视图1.部分是   项目名。和Picker视图2.部分是项目编号。我想要   写在我的标签上相同的选择器视图是1.我想在标签上写的部分   “A1 Unitesi”，我想写在label2“002”，但我的标签上   写“DevamEdenProjelerObje：”0xada6fe0“＆gt;为什么在我的标签上写   “DevamEdenProjelerObje：”0xada6fe0“＆gt;？`你能帮我吗？我怎么能   在我的标签上写着“A1 Unitesi”？

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
        return 2;
    }

    - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
    {

        if (component == 0) {
            return [RaporlarList count];
        }
        return [RaporlarList count];

    }

    #pragma mark Picker Delegate Methods
    - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
    {

        if (component == 0) {
        eObje =  [RaporlarList objectAtIndex:row];
        return  eObje.ProjeAdii;

        }
        eObje = [RaporlarList objectAtIndex:row];
        return eObje.ProjeNoo;
    }

    #pragma mark -
    #pragma mark PickerView Delegate

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

        if (component == 0)
        {
            NSString *resultString = [[NSString alloc] initWithFormat:@"Proje Adı : %@", [RaporlarList objectAtIndex:row]];
            lblProjeAdi.text = [NSString stringWithFormat:@"%@", resultString];

        }
        else
        {
            NSString *resultString = [[NSString alloc] initWithFormat:@"Proje No: %@", [RaporlarList objectAtIndex:row]];
            lblProjeNo.text = resultString;

        }

       }

我不知道我是否理解得好但是不是更好吗？

if (component == 0)
    {
        NSString *resultString = [[NSString alloc] initWithFormat:@"Proje Adı : %@", [[RaporlarList objectAtIndex:row] ProjeAdii]];
        lblProjeAdi.text = [NSString stringWithFormat:@"%@", resultString];

    }
    else
    {
        NSString *resultString = [[NSString alloc] initWithFormat:@"Proje No: %@", [[RaporlarList objectAtIndex:row] ProjeNoo]];
        lblProjeNo.text = resultString;

    }
