问题
I have 200+ uiLabels added to a long (92000px) uiScrollView. I am getting the impression from some of the QAs that one option to improve performance is to pre-render the whole view into one?
I basically add my uiLabels in a for loop inside ViewDidLoad to a scrollview.
Could someone give me a few ideas for how you could go about rendering all those uilabels to a single layer? then add that layer to the uiScrollView?
(I mention single Layer, I don't know anything about layers, I am just making an assumption)
many thanks for any ideas...
