UILable 的自使用 iOS

注意：要设置uilabel的行数为：不限制行数

设置该字典大小的时候注意：前后的字体的大小都要设置，而且要保持一致。

NSDictionary *dictAttribute = @{NSFontAttributeName:[UIFontsystemFontOfSize:14]};

        CGSize size= [self.filteredCities[indexPath.row]boundingRectWithSize:CGSizeMake(self.view.frame.size.width,40) options:NSStringDrawingTruncatesLastVisibleLine |NSStringDrawingUsesLineFragmentOrigin | NSStringDrawingUsesFontLeading attributes:dictAttributecontext:nil].size;

        CGRect frame1 = self.lbTitle.frame;

        frame1.size = size;

        self.lbTitle.frame = frame1;

        self.lbTitle.text =self.filteredCities[indexPath.row];
