in the There are often problems in iOS concurrent programming, we are not here to explore the specific usage of nsthread, GCD, Nsoperation, Nsoperationqueue, but to explore some easily forgotten dots. I hope that the vast number of iOS developers can play a certain help. Thread coston Wikipedia The explanation of the thread is :A thread of execution is the small
do not need to writeCodeBut this is only applicable to simple UI applications.
2. Adjust the View frame (frame attribute)
Each UI element is defined by a rectangle area on the screen. This rectangle area is the frame attribute of the UI element. You can use the C function cgrectmake (X, Y, width, height) to redefine the frame attribute of a view.
If there are many UI elements, You need to track the size and position of each UI element, and the code design is troublesome.
3. Redesign diff

People with programming experience will basically be exposed to multithreading.
In Java and Android development, a large number of background operations and asynchronous message queues are basically implemented using multithreading.
Similarly, IOS Mobile development and Android are basically similar models.

routines and NSThread classes are recommended to create low-level threads, other C-language-based technologies are also available on Mac OS X. Among them, the only one that can be considered is the Multiprocessing Services, which itself is executed on the POSIX thread. The multi-processing service was developed for earlier Mac OS versions. Later, it was applied to the Carbon application in Mac OS X. If you have code that really has this technology, you can continue to use it, although you shoul

When iOS 8.0 and OS X v10.10 were released, a whole new concept came to our eyes: Application extensions. As the name implies, app extensions allow developers to extend the app's custom features and content, allowing them to use the feature when using other apps. You can develop an application extension to perform certain tasks that users can perform in multiple contexts after they use the extension. For example, you provide an extension that allows u
