Millistes olukordades ja kohtades peaks kasutama objektide vahemälu?

Object caching in iOS should be used when:

• Data or resources (e.g., images, network request results) are frequently used and their retrieval or computation takes significant time.
• It is necessary to reduce the load on the network or processor.
• Ensuring a smooth and fast user experience is important.

Typical caching locations:

• In memory (e.g., NSCache) for quick access to recently used objects.
• On disk to store large or rarely changing data.

Example: caching images loaded from the network so they do not need to be reloaded upon redisplay.
