My requirement is not to use images in multicolumn, but rather use it more like a spreadsheet, with 6 columns and variable rows and with alternating color
举个例子,当我们在用网易新闻App时,看着那么多的新闻,并不是所有的都是我们感兴趣的,有的时候我们只是很快的滑过,想要快速的略过不喜欢的内容,但是只要滑动经过了,图片就开始加载了,这样用户体验就不太好,而且浪费内存. 这个时候,我们就可以利用l
学习如何在你的app中使用NSOperations! 这篇博客是由iOS个人开发者Soheil Moayedi Azarpour发布的。 每个人都会在使用iOS或者Mac app，点击按钮或者输入文本时，有过让人沮丧的经历，突然间，用户交互界面停止了响应。 你真幸运 - 你只能盯着沙漏或者旋转的风火轮一段时间直到能够再次和UI界面交互为止! imageView.frame = CGRectMake(borderWidth, borderWidth, blackBG.frame.size.width-borderWidth*2, blackBG.frame.size.height-borderWidth*2); 双列表联动 用过了那么多的外卖App，总结出一个规律，那就是"所有的外卖App都有双列表联动功能"。哈哈哈哈，这是一个玩笑。 这次我也需要开发具有联动效果的双列表。也是首次开发这种类型的UI，记录下步骤与心得 一、关键思路 懒加载左右2个UITableView 根据需要自定义Cell 2个UITableView加载到 Adding chat to your app can be a quick way of going from having just another mobile app to an app that allows users to connect with one another. Whether your app is about connecting employers with job hunters, sellers with buyers, daters with one another, or something else entirely - your users will surely apprecaite the easier and more direct communication.

But it doesn't do anything when the user scrolls down the list. Here's where the Prefetching API comes to the rescue. 附上效果图 第一步 要想看到tableview的多选模式，这两句代码必不可少 1.设置为编辑模式 [self.tableView setEditing:YES animated:NO]; 2.设置编辑样式为多选（两个属性加起来就是这么神奇） -(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingSt
the cell in aviewcontrller indexpath(get notification posted bviewcontroller)**is invisible. you can reload whole table view in viewdidappeare method. work every time go bviewcontroller.or keep performance in mind can reload visible rows:[tableview reloadrowsatindexpaths:[tableview indexpathsforvisiblerows] withrowanimation
indexPathsForVisibleRows returns [AnyObject]?, but you are trying to assign to a non optional [NSIndexPath] variable. If you just let type inference do the job the code compiles: let visibleIndexPaths = self.tableView.indexPathsForVisibleRows() That returns an array of AnyObject, so probably you want to downcast to the proper type, but in this Say you have a view controller with a table view, and you want to load 100 rows of data into it, these data are retrieved from a web API, how would you approach this?
