Apple is one of the leading companies in the world of IT in the market. Why? The reason for their popularity is simple due to their user-friendly features and iPhone application development that come in their products like iPhone, iPad etc. The company provides products in the field of hardware, developer tools and the operating systems. These products can gel easily with each other so that the iPhone developers can make great apps for users.
The X code developer tools provide you with a great, user-friendly, iPhone development environment that includes everything you need to build great Mac OS X and iOS apps.They provide the iPhone developers an environment that makes it convenient for them to develop different applications such as the instruments.
Features in the Instruments
The features in the various instruments are elaborated below.
With this feature, the iPhone users can visualize the various relationships between the different types of data recorded and displayed or the same data collected during the multiple runs.
This unique feature designed by iPhone developer in which the developer and user can see the data spikes on graph and can fix the problem in executing code with the help of Xcode.
With the play back facility an adhoc test is created in which the user interaction with the application is stored and it can be played back to see the effects in the performance by the changed code.
This fascinating feature enables not only users but also iPhone developers to choose any instruments in the library from low level CPU, file activity and network and can shift it to the more advanced and user events instruments.
We all know that the zombies are to find similarly, when there are system crashes or there are invisible application errors or the memory that is no longer accessible. This feature is the remedy to these problems as these errors can be stored in the instruments.
Sometimes when the person is viewing application he wishes to see the source codes to detect the data point or the methods that are consuming more CPU time .This is possible with this feature as the user can use the instruments UI. The user can identify the problem in the application and can rectify it so that the result is there in less time and is error free.
We as the user of new applications in the new iPhone will like to know beforehand the high fidelity of the application in the instrument .With this feature the user can have sample of performance data of the application with a simple press of key with low overhead cost.
The users can build their own instruments by using DTrace and the instruments custom builder according to their needs and requirements to raise their performance graph with minimum errors.
The system trace is the feature with which the instruments records all the information about all the processes in the system and the bottlenecks caused by the various processes interaction with minimum resources.
