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);
