Introduction to iOS instrumentsIntroduction to iOS instruments When writing code, we often need some tools to help us analyze and locate problems to adapt and optimize the code. In terms of iOS development, XCode provides a series of tools to help us solve the problem. This is instruments. The apple documentation introduces instruments as follows:

Instruments has recently been used to analyze the performance of the entire application. Discover a lot of interesting points, as well as performance optimizations and some techniques for analyzing performance consumption, summarized below.Instruments Tips for useAbout Instruments official has a very useful user to use guide, of course if not accustomed to the official English can be found here in the text

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 understand the principles. How to use instruments to findProgramAnd how to use nszombieenabled. This article assumes that you are familiar with the obj-C memory management mechanism. Development Environment of the experiment: xcode 4.5.2 1. Run the demo. Download

iOS performance optimizations: Instruments toolsPreface: Even if the cow programmer, write the great code still there are many optimizations, not to mention our ordinary programmers write the ordinary code (such as the author) there are many optimizations and bugs need us to debug. So code optimization is the skill we have to master.Today I introduce you to a Code Analysis Optimization tool: Xcode comes with the detection debugging tool instruments.In

I recently used the Instruments tool and found it very helpful for tracking memory leaks in the game. Since I discovered that Instruments are so useful, I think writing an article about how to use it to track memory leaks can also help others.What is memory leakage? Why do I need to care about memory leakage?... This section is omitted...Visit Wikipedia to obtain more information about memory leakage.How do

Is your IOS app running at a fast pace? The students in the gun to worry about, performance optimization We have a wonderful trick. With Xcode Home Debugging tool Instruments, pull out those blocking threads, account for memory, consumption of resources, the problem code, completely break down the fan, let the application elated!For every IOS developer, code performance is a topic to avoid. With the expansion of the project and the increase in functio

Compared with a lot of instruments or found that the foreigner wrote more. So decisive translation. Able to see the original English, encourage everyone to see the original material away from the second-hand tutorial. This is the original.EntryIn order to save everyone's time, provide a demo of the demo to everyone. Code portal.Download and unzip and open with Xcode.After compiling and running the app and entering any words in the search box, click on

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 understand the principles. This article describes how to use Instruments to find memory leaks in the program and how to use NSZombieEnabled without ARC. This article assumes that you are familiar with the Obj-C memory management mechanism. Development Environment of the ex

released and use the object, two is If you use the instruments tool to detect memory leaks, this use of autorelease will also be treated as memory leaks, pay attention to identify .... 8 for Nsmutablearray This kind, when AddObject, when the corresponding is added to the array of the object's reference count will be + 1, when the array itself is released, it will first send a release message to all objects in the array.

Detecting memory leaks: leaks in instrumentsObjectiveIf you want to detect a memory leak, we will use the leaks tool in the XCODE7 instruments to detect.The current development environment is arc, so there are few memory leaks. But we must keep good code of the normative. For example: Use notification, do not forget to remove; Use Presentviewcontroller to eject the new controller, don't forget dismiss and so on.If a memory leak occurs, a third-party f

Reprint: http://www.zhimengzhe.com/IOSkaifa/255950.htmlThe previous article I introduced Instruments's tool classification and basic use method, today I come to you to talk about leaks use method.In the early development of iOS, there was no arc mode, only the MRC mode, the developer must manage the memory, the process is very cumbersome and easy to cause memory leaks, today's iOS development although the basic use of the ARC mode, but in some cases, we need to manage the memory, slightly carele

iOS Development 74-xcode (7.3.1) uses the instruments (7.3.1) test memory leak example (circular reference) to intentionally write a memory leak code, circular reference in the ARC environment. Two objects are strong references and point to each other, resulting in a memory leak. -(void) viewdidload { Leakmodel * Leaka = [[Leakmodel alloc]init]; Leaka.myname = @ "Leaka"; Leakmodel * leakb = [[Leakmodel alloc]init]; Leakb.mynam

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

In iOS 5.0 and later versions, the ARC mechanism is added. However, memory leakage may still exist due to the complicated mutual reference relationship. Therefore, it is important to understand the principles.This article describes how to use Instruments to find memory leaks in the program and how to use NSZombieEnabled without ARC.This article assumes that you are familiar with the Obj-C memory management mechanism.Development Environment of the expe
