So I have asked a similar question before but this one is a little different. Previous conversation: Is there a pointer for each touch point in ios
From this I get the entire touch event information. Which is really nice to have. But the information comes out like this for a single touch event:
<UITouch: 0x7b657920> phase: Began tap count: 1 window: <UIWindow: 0x7b65e150;
frame = (0 0; 768 1024); gestureRecognizers = <NSArray: 0x7b65e590>;
layer = <UIWindowLayer: 0x7b65b940>> view: <UIView: 0x7b660b90;
frame = (0 0; 768 1024); autoresize = W+H; layer = <CALayer: 0x7b660640>>
location in window: {252.00002, 562.00012} previous location in window: {252.00002, 562.00012}
location in view: {252.00002, 562.00012} previous location in view: {252.00002, 562.00012}
I need to figure out a way to just get the information at the beginning. The pointer right after the UITouch: I would prefer not to have to transfer this to a different array of these pointers but if need be I will. I know how to do that. I was just wondering if anyone knew how to get that pointer out of there without having to do all the extra processing.
Thanks.
I assume you have that long list of pointers and information in string format, so to obtain just the "0x7b657920" you could just do something like:
var str = descriptionString //The info from the touch event
let rangeOfPointer = Range(start: advance(str.startIndex, 10),
end: advance(str.startIndex, 20))
let pointerStr = str.substringWithRange(rangeOfPointer)
Hope it helps :)
