release of the iOS 6 system, an AutoLayout technology can be used in iOS development. AutoLayout like a Web page, specify the relative position between the view,button,text, such as how much to the left, how much to the right, how much to center, and so on. For example, a simple layout like the following.Suppose the upper-left corner is View1, the upper-right corner is VIEW2, and the following area is VIEW

IOS development UI layout and iosui Layout This article will be updated on a regular basis. With my in-depth study of the layout, I will constantly add new knowledge, new usage skills, and new understandings. 1. Autoresizing (used in code) First, let's take a look at the following code and the running results on the left. Then, we will rotate the iPhone simulator and then look at the results. Then, we can take a look at the autoresizingMask attribute in the code to see it: After the landscape

This is often the case when using Table view: The contents of the cell in the table view are dynamic, resulting in a cell's height being not known at the time of development, so it is necessary to provide an algorithm for calculating the cell height, each time it is loaded into this cell Calculate the true height of the cell.Prior to IOS 8Without using AutoLayout, you need to implement the TableView (Tableview:uitableview, Heightforrowatindexpath inde

Preface: This essay will be updated frequently, with my deep study on the layout, will continue to add new knowledge, new use skills, new understanding and so on.1. autoresizing (used in code)Just look at the code below, and the effect on the left, then rotate the iphone emulator, then look at the effect, then combine the Autoresizingmask attribute in the code to realize:After a horizontal screen, the default frame (0,0,100,500) on the vertical screen will be placed in the middle of the screen a

need to serialize the data and map the data to the custom domain model object and the storage-understanding format. The "map" chain used to read the data is as follows: db->?raw data format->?custom domain models, and is used to write this: custom domain models->?raw data format- gt;? Db. You can do this here using the Nsmanagedobject or nscoding protocol.Note:The main note here is not aware of the need for these data operations when using the network and storage tiers of the iOS application. T

implicitly gives view some constraints constraints to ensure that the view size does not change. In this example, view is added to the 4 constraints of top,left,width,height.If we need more dynamic resize behavior, we need to customize the constraints within IB. Now that's the problem, is there a better way to do it? It is better to have a method without restraint, but also to achieve a simple resize effect.Now there is a solution to the problem. In Xcode8, we can assign a autoresizing masks to

coordinates have changed, the height increases 568-480 = 88 points, then uses the absolute localization way, will cause the program height is not enough, if the program does not fit, the system will be the extra 88 points will be automatically divided into two parts , making black edges appear up and down. corresponding to different models, screen coordinate size has changed, can no longer be absolutely positioning, in order to solve this problem, iOS has a new technology:AutoLayout.

Today's blog content on the system to discuss the impact of masonry on FSP, and how to better use the masonry. If you are familiar with iOS development, then you should not be unfamiliar with the masonry framework. Simply put, the birth of masonry makes AutoLayout more elegant to use, making the layout of the control more convenient. When you look at a thing with a dialectical perspective, there are two sides to everything, and the use of masonry is n

Turn from: http://www.code4app.com/blog-822717-1471.html For the iphone x adaptation, the main work to be done is to match the upper and lower unsafe areas. In iOS development, there are two ways of Xib and code editing for layout. Both of these methods support absolute layout and AutoLayout two kinds. Next, we'll explain how to automate the iphone x from Xib, code editing, absolute layout, and AutoLayout
