moveRowAtIndexPath doesn't refresh the cell's content

问题 iOS 5 finally added a moveRowAtIndexPath:toIndexPath: method to UITableView . Problem is, calling it only moves the row, it doesn't update/redraws it. The only way to do so seems to be by finding the cell and calling setNeedsDisplay directly. But this is tricky since you never know whether the cell already got moved or not. I can't call reloadRowsAtIndexPaths: either, since I'm not allowed to have 2 animations applied to a single row inside the same beginUpdates-endUpdates block. There are

Best Practices: Fast UITableView Scrolling?

问题 I know there has been a lot of discussion around fast scrolling. Apple provides excellent examples: http://developer.apple.com/library/ios/#samplecode/TableViewSuite/Introduction/Intro.html I will have a custom UITableViewCell that has 2 UIImageView's and 3 UILabels as subviews. If I just add them as subviews to the content view will my scrolling be slow? Would it be best to just draw these? 回答1: The answer I got from the UIKit guys at WWDC this year was "it kinda depends on what you're doing

由 巧了我就是萌 提交于 2020-02-03 00:48:43
苹果WWDC开发者大会上，终于发布了大家期待已久的iOS 11，有些新特性功能确实出人意料。不过大的方面苹果貌似也就 AR 和 GM 机器学习了，9月13日凌晨1点，苹果开了新品发布会，相信大家都已经知道Phone X 的刘海了，看起来不是很雅观，对于iOS开发者来说，适配工作也带来了麻烦，iOS11在新旧API 方面做了新的改动，未来App Store就会出现很多大量的APP更新，针对iOS11和iPhone X的适配。 下面针对已经了解的出现的问题进行适配的说明。 屏幕未充满？ 相信一部分开发者已经在着手适配iPhone X 和iOS11 了，xcode9测试版运行自己的项目会发现项目没有充满屏幕，上下会有黑色区域的情况，大家别慌，这是没有设置对应的启动图，iPhone X对应像素 1125 * 2436 大家可以自己添加图片或者准备一张尺寸:1125 * 2436的启动图片, 移动到LaunchImage的Finder目录中, 并在LaunchImage中的Contents.json文件中增加 (注意Json格式): { "extent" : "full-screen", "idiom" : "iphone", "subtype" : "2436h", "filename" : "图片名字.png", "minimum-system-version" : "11.0",
