本文介绍如何使用Objective-C从资源包中加载Plist文件，并解析其内容。此外，还介绍了iOS 7之后引入的新函数，用于动态调整UILabel的高度以适应文本内容。

读取plist文件

NSString *plistPath = [[NSBundle mainBundle] pathForResource:@"testData" ofType:@"plist"];
    NSMutableDictionary *data = [[NSMutableDictionary alloc] initWithContentsOfFile:plistPath];
    _tableItems = [data objectForKey:@"data"];

动态调整uilabel高度

io7之后的新函数

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc]init];
    paragraphStyle.lineBreakMode = NSLineBreakByWordWrapping;
    NSDictionary *attributes = @{NSFontAttributeName:descriptionLabel.font, NSParagraphStyleAttributeName:paragraphStyle.copy};
    CGSize descriptionLabelSize = [descriptionLabel.text boundingRectWithSize:descriptionLabel.frame.size options:NSStringDrawingUsesLineFragmentOrigin attributes:attributes context:nil].size;
    descriptionLabel.frame = CGRectMake(8, CGRectGetMaxY(nameLabel.frame) + 3 + descriptionLabelSize.height, kTABLEVIEW_WIDTH, descriptionLabelSize.height);
