What is the largest amount of memory, in bytes, that I can safely allocate in one block on an iOS device?
It’s not a fixed number – it depends on phone model and SDK version. It also depends on how many other app’s are running on the device and at what point during the program execution that the request was made (memory spikes tend to get your application terminated quickly). To be frank, it’s impossible to give a definitive number but it ranges from 20 to 100MB.
