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 is still in use causes corruption of memory along with the malfunction of the given application such as crashing, corrupted data, and many times worse scenario than this.

Not clearing data that are no more in use may lead to a 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 the 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 the 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. Similarly, sub-objects belonging to any object will clear when it’s cleared on a whole.

Memory Management Tools
