I don't think you will get anywhere arguing about loss of view due to trees. You can however go for loss of light into your apartments.
I know with council and development applications, neighbours can complain about any loss of light into their homes but not necessarily view.
Our OC lets owners plant in the common garden areas outside their lots as long as these plants are in keeping with the overall appearance of the complex. The OC also reserves the right to remove trees/plants that are deemed not to be in keeping. Only had to have one tree removed so far.
You could also argue any leaves dropping onto your balcony, blocking any drainage points. Any seeds/fruits that may also drop, stain or be a danger to children. And depending on how high and what type of trees are planted, you could point out that the root systems of these trees may cause problems with plumbing or if too close to the structure, foundations.
Perhaps you could ask the OC to arrange more appropriate plantings that avoid all of the above.
