I have a ScrollView with multiple UIImageViews in it which load .jpg images. It runs pretty influently when loading images.
How can I optimize the images to make iOS load them faster? Use which tool? In which specific format and setting? Thank you.
have them as png and pre load them with the “imageNamed” method. This method WILL cache them which makes loading fast. but it also knows how to handle memory which means it will unload them if you are runing low on memory.
Alternatively, depending on the size you can create the thumbnail version of these images for display. This is how the imagepicker manages to display A TON of images very fluently.
