Table View memory consumption

I have created a table and populated with some data.

Whilst monitoring the memory consumption of my app I noticed the consumption rise when loading the table with data. When deleting the data from the table and data source the memory consumption of the app did not drop.

If I continued the cycle of load data and then remove data the memory of the app continued to rise and was not released.

At startup the memory allocation was approx 30mb and rose to 40mb through the cycle of adding and deleting data.

Has anyone else noticed this effect and is there a solution.
