根据文字计算label的宽度和高度

// 滚动条中的描述文字

UILabel *desLabel = (UILabel *)[appCell.mAppDescription viewWithTag:101];

　　　desLabel.numberOfLine = 0;

desLabel.text = _appDetailModel.mDescription;

NSLog(@"desLabel.text = %@", desLabel.text);

UIFont *font = [UIFont fontWithName:@"Arial" size:10];//跟label的字体大小一样

CGSize size = CGSizeMake(300, 29999);//跟label的宽设置一样

NSDictionary * dic = [NSDictionary dictionaryWithObjectsAndKeys:font, NSFontAttributeName,nil];

size =[desLabel.text boundingRectWithSize:size options:NSStringDrawingUsesLineFragmentOrigin |NSStringDrawingUsesFontLeading attributes:dic context:nil].size;

appCell.mAppDescription.contentSize = size;

// 徽章不隐藏
