The height of UITableViewCell calculates the height of uitableviewcell from the beginning of chaos to the intersection of Heaven and Earth.[Original] UITableViewCell height calculation from chaos initial to Tianji jiaotai This article is based on the highly adaptive computing problem of iOS UITableViewCell: The UITableView control may be the most commonly used control in iOS (rolling view, cell reuse, and choppy optimization). Today we are not talking about these high-level topics, today's topi

In the growing number of apple rings, even if the mobile phone application alone, in the screen size judgment is no longer an if can solve the problem. Apple's new Sizeclass on IOS8 is a feature that matches the previous AutoLayout use and perfectly solves the problem of screen adaptation. Sizeclass the width and height of the screen into three situations: compact, arbitrary (any), normal (Regular), 22 combined, 9 categories, so Sizeclass looks like a

new task has just been created on the iPhone? You don't need to think about it. The cost of building a wheel is high and prone to problems. MMWormhole is recommended here. It is a mature and stable third-party open-source library used for communication within the App Group, which is very convenient and easy to use. I will not talk about the principle. If you need it, you can download it and study it. When building the UI, you will find that Apple Watch does not support

self.view.translatesAutoresizingMaskIntoConstraints = NO; Self.view represents all the view you want to add a constraint to2. In a view that uses AutoLayout layout, the code avoids the code that sets its frame-related properties (such as center), but can get its frame;3, when the code for Xib or SB in the view to increase the constraints, try to avoid viewdidload in the execution, preferably in updateviewconstraints[uiviewcontroller] or updateconstra

project's storyboard, not just the iphone 4s-5/5s-6-6 Plus, but also the ipad interface . It introduces a new concept that discards the so-called specific wide-height dimensions that we fit in the traditional sense, The width and height of the screen are divided into two cases :compact-Compact, regular-normal (any-arbitrary, is actually the combination of these 2, so I did not divide into 3 cases). It's 3. * *, that is, regardless of the change, add up to 9 kinds, such as. (However, it is sti

Below, you will create a swift project and then introduce 3 libraries: Snappy simplifying the library of AutoLayout code Alamofire HTTP network library, written by afnetworking authors Sdwebimage picture loading, OBJC project, via header file bridge mode for Swift use Among them, the first two are Swift's library, SDWebImage is OBJC's library.Source code See: Https://github.com/MarshalW/SwiftWith3rdLibDemoThe project runs like t

is, 68/20=102/30. Unfortunately, the flaws in these technologies are also obvious and are an immature technology for two reasons:(1), autoresizingmask scaling is calculated internally by Uikit, and the developer cannot specify the exact value of the zoom scale.(2), the change rule can only be based on the parent-child view, unable to solve the sibling view of the position relationship. So after IOS6 introduced the auto layout technology, Autoresizingmask became a chicken technology. Can use the
