Sometimes, we need to dynamically change a value in the AutoLayout in view, such as moving the X-value, or the Y-value, what to do?The following encapsulates a better way to remove: excerpt from Https://github.com/MakeZL/ZLAutoLayout (the framework that encapsulates AutoLayout)The following is used to Zllayoutconstraint is an alias Nslayoutconstrainttypedef Nslayoutconstraint Zllayoutconstraint;------------

Scenario Description: Sometimes we want to update the data for one cell, and it's common practice to update the entire cell with the Reloaddata method. However, it is not applicable to some situations or it is more troublesome to realize it. For example, this simple "point-and-click" cell The hero's profile is replaced with "Click to view Details" and the download button is set to hidden when it is not opened. In this case, if the data is reload the entire table at the point of opening, the tabl

When using AutoLayout, you need to add the following code before the animation Layoutifneeded method Animation AutoLayout can also be combined with the traditional animation method, the overall code structure is as follows. 1: 2: 3: 4: //... update constraints 5: 6: XiOS Development tips--

With more and more Apple models, multi-model adaptation has become a problem, some computing screen size , some with autoresize, personal Feel the best use or Apple provided AutoLayout. Of course, everyone's preferences are different, it depends on their own preferences. The AutoLayout implementation of the multi-model adaptation of the master is used to constrain the position of the control by being able t

When using storyboard and xib, we often use ScrollView, as well as automatic layout autolayout, but ScrollView and AutoLayout are used in a relatively complex sense. According to the practice, I say my understanding, in the storyboard or Xib, ScrollView determines the size of the contentsize based on the size of the view below it.Take a look at the effect1. Create a project, drag a scrollview into the story

If one of its x,y,height,width is not set, it will be an error. The x, y settings can be set for specific data, can be aligned relative to left and right, or can be modulated relative to the horizontal vertical average. Height,wid

Android AutoLayout the new adaptation method is a Terminator. I. Overview I believe that Android Developers are worried about configuration issues. Although Google provides a series of suggestions, it is quite difficult to simply use these suggestions to make the device easy. I also pay more attention to adaptation issues. I have also published several articles on adaptation, which are roughly as follows:Android screen adaptation solution: percent-

perfect adaptation is achieved, and most importantly: No longer need to take the design to figure out how much DP the control's width is going to take. No more need to write multiple dimens for multiple screens You don't have to calculate the percentage anymore (if you use a percent control to complete the adaptation) I don't have to explain to the UI mm what DP is anymore. Next use.Address of this library: Https://github.com/hongyangAndroid/AndroidAutoLayoutIii. usage

(1) Use size Classes in storyboard.We have used AutoLayout before, and now we have a size Classes, which can be seen as AutoLayout settings under different size Classes.Detailed tutorials, http://www.cocoachina.com/ios/20141020/9978.html--Seemingly, storyboard's functions are becoming more powerful. The adaptation of different sizes and screens is enough to make it a pain to hit the code.--Find a lot of blo

Autolayout allows you to assign a value directly to the label without calculating the width and height of the text. The label automatically adjusts the width and height of the text. If you specify the topmargin and left margin of the label The bottom margin is set to> = 300. Then re-set the label content in viewdidload. At this time, you will find that the label will automatically increase dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(

Use Autolayout layout in UIScrollView (1), uiscrollview I have translated how to use UIScrollView (multiple contentviews) in AutoLayout (hereinafter referred to as "how"). This article explains in detail the restrictions and precautions for using automatic layout in UIScrollView. I thought it was clear. However, some readers still say that the examples in this article are feasible, but they cannot achieve t

Autolayout code implementation example-02-use VFL 0. Introduction: VFL stands for visual format language, which can abstract the layout of one or more views. VFL is simpler than autolayout using linear formulas. 1. Example 1 Requirement: create two views, one in blue and one in red. The distance between blue and the top, left, and right of the screen is 20, make the spacing between the top of the red view a

In the second case, if the label adds only the upper left constraint, the text that
