IOS之从plist文件中获取数据

               1.定义数组

        NSMutableArray *_foodArray;

        2.从文件中读取plist文件路径（foodData是你plist文件的名字）

        NSString *foodPlistPath =[[NSBundle mainBundle] pathForResource:@"foodData" ofType:@"plist"];

        3.初始化数组

        _foodArray = [[NSMutableArray alloc] initWithContentsOfFile:foodPlistPath];

        4.获取plist文件数据（image，newPrice，oldPrice为plist文件中的key）

        NSString *imageName = [foodArray[i] objectForKey:@"image"];

        NSNumber *newPrice = [foodArray[i] objectForKey:@"newPrice"];

        NSNumber *oldPrice = [foodArray[i] objectForKey:@"oldPrice"];

        5.通过tag获取相关控件的一些属性

        UIImageView *imageView = (UIImageView *)[self viewWithTag:20+i];

        6.对imageView相关属性赋值

        imageView.image = [UIImage imageNamed:imageName];

        UILabel *newPriceLabel = (UILabel *)[self viewWithTag:50+i];

        newPriceLabel.text = [NSString stringWithFormat:@"%@元",newPrice];

        UILabel *oldPriceLabel = (UILabel *)[self viewWithTag:70+i];

        NSString *oldStr = [NSString stringWithFormat:@"%@元",oldPrice];

        //在oldPrice的数据上设置中划线

        NSDictionary *attribtDic = @{NSStrikethroughStyleAttributeName: [NSNumber numberWithInteger:NSUnderlineStyleSingle]};

        NSMutableAttributedString *attribtStr = [[NSMutableAttributedString alloc]initWithString:oldStr attributes:attribtDic];

        oldPriceLabel.attributedText = attribtStr;
