Most of the western orchestra's musical instruments originated in Europe. As early as a few centuries ago, the orchestra began to take shape and was generally used to play court music. At first, the band only used some stringy instruments. Later, it gradually added woodwind and brass instruments. In general, the western orchestra is composed of a keyboard inst

Instruments is a dynamic analysis tool. It is integrated with xcode and can be started in xcode through the menu product → profile. Start, instruments has many tracking templates for dynamic analysis and tracking of memory, CPU and file systems. Each trace template has different purposes. leaks can detect memory leaks, and allocations trace templates can view memory usage. Here we will introduce the use of

expression and transmission of parameters in experimental instrumentsOriginal reason Description:In the different experimental instruments, the realization of signal transmission, in fact, can be converted to signal parameters of transmission. Therefore, the synchronization and refresh of each experimental parameter is the key to express the logic relationship of the instrument. The parameters that the instrument needs to pass can be string, double, l

Instruments is a performance tuning tool integrated in Xcode that provides developers with a number of useful features that are now slowly being learned and summarized.Instruments provides many features to view time-consuming, CPU-intensive, memory-leak, and so on, which can help us to optimize the performance of our products.To open instruments, you can use this procedureBelow, I'll start learning to summa

SELF: it seems that this leaks tool is not always correct. I ran into the program for a while and it showed that there was a red column, but it must have been located in the main function. I asked a buddy in the group that he didn't care too much about it. It may be a system problem. Just let me know first! Although the arc mechanism is added to iOS 5.0 and later versions, memory leakage may still exist due to the complicated mutual reference relationship. Therefore, it is important to understa

Hard Canton: "iOS Performance Tuning Series", the second, continuously updated, welcome attention.The first article introduces the static analysis of analyze to the app, can find out the memory leak problem in the application, for some memory leaks can not be solved by static analysis, it could be discovered by dynamic analysis, and the analysis is more targeted.From the beginning of this article, we introduce the powerful analysis tools provided by Xcode in
