Crashes with large test files

Open Boyeen opened this issue 10 years ago • 6 comments

I noticed this in my own code but also in the demo. Everything works fine for small snippets but a largish file, say 100+ lines of code, allocates more and more memory then ultimately is terminated after scrolling a while. In fairness, I'm convinced this is due to memory leaks with UITextView in iOS7. I'm just wondering if anyone has found a workaround. It makes CYRTextView unusable for my purpose.

Hi Boyeen,

Good catch. I'll investigate this issue and see what I can find.

Hi Ilya,

Any further insight? As I'm sure you have found, iOS7 has some horrible bugs. The worst seems to me the poor memory deallocation algorithm. I am certain the bug I reported to you is not in your code, I see it in a regular UITextView with 1000 lines of code. I think it is related to ARC and the ongoing crashes of Springboard, especially in A7 devices. iOS7.1 helped a little but nowhere near enough. So, I would welcome your input.

BTW I really love the look of CYRTextView and plan to use it in my own app when I can reliably scroll 1000 lines of code.

Boyeen, did you fix the issue with large files?

Nope. It's very frustrating. It seems to be a problem in ARC/iOS7. If you try, you can recreate it using a totally standard UITextView although the memory usage doesn't grow as fast without the annotated strings.

Boyeen, what do you think about the following issue? https://github.com/illyabusigin/CYRTextView/issues/17

hey @Boyeen , so, I have the same issue and noticed big performances issues when opening a large file , and scrolling.

If you shortcut the drawRect method (it only makes the line gutter fancy), the scrolling problem will go away. I'm planning on working on a PR to improve the perf of the drawRect.

For the problem of opening big files (it takes a while to process and display it) I'm still investigating what is the issue.
