iOS – Memory Management
This was generally a non- Automatic Reference Counting for retaining along with the release of objects. It also aids ARC which made the user free form retaining and release of objects.
Issues related to Memory Management
Get the current market trends updates from the industrial experts by joining our IOS Course in Chennai. Two issues are critical in memory management:
· Overwriting also known as freeing of data that are still in use that causes corruption of memory along with the malfunction of the given application such as crashing, corrupted data and many times worst scenario than this.
· Not clearing data that are no more in use may lead to memory leak. It is necessary to free the memory allocated for any data that is idle for time being in order to accomplish the other process smoothly. If not done on time this may lead to poor performance of the system and further affect the whole process.
Memory management rules
· The objects we create are the ones we own followed by its release when there is not any more requirement of this.
· Deployment of ownership when we do not create the object.
· Avoid release of objects that are not owned by you.
Handling Memory in ARC
It is not necessary to release along with retention when the object is not under usage. Thus, every single view controller is released during its removal. In a similar manner, sub-objects belonging to any object will cleared when its cleared on a whole.
Memory Management Tools
It is possible to analyze the memory usage with usage of Xcode tool instruments that consists of tools namely Allocations, Zombies, Activity Monitor, Leaks, and many more. Get thorough information related to IOS by joining Mobile Application Development Training in Chennai.
iOS – Application Debugging
It is usual to commit mistakes as we are humans and committing mistake is our nature. When the mistake occurs during the process of developing of any application, it may lead to various errors. Thus, in order to fix the errors it is necessary to debug the entire application, which will lead to the proper functioning of the application.
Selection of a Debugger
The Xcode consists of two debugger called GDB and LLDB. The GDB is considered to be selected by default. The selection of LLDB debugger is a part of LLVM open-source compiler. Here the user is able change debugger by simply making use of “edit active schemes” option. Enroll yourself into one of the leading IOS Training Institute in Chennai.
How to Find Coding Errors?
In order to locate errors related to coding the user need to build any application that will be able to compile the code. In such case code consists of errors, and the compiler is able to display all errors, messages, along with warnings with possible reasons.
Setting up of Breakpoints
The deployment of Breakpoints help the user to know various states of any application objects that aids the user in identifying several flaws that includes logical issues as well. The user needs to click the line number in order to create breakpoint. For the removal of breakpoint user just needs to click and drag it out.
The presence of exception breakpoints is to trigger any application in order to stop the location in which the exception takes place. Thus, join IOS Training in Velachery for further clarifications.
