ios - Most efficient way to check number of CGPoints in CGPathRef -

-

I have to find out that my CGMutablePathRef has more than 3 digits! It will often be checked that I am looking for an efficient solution.

For this reason I need to do this because the user draws the shape in my project. As the user leaves his finger, a CGPint (the finger of the current location) is added to the path and a physical body is added when called touch aded. Now if the user taps the screen then only in CGMutablePathRef One point is this (my argument in my head) and when I use my CGMTable Pathfreck to connect the physical body, I get the following error. Convergence failed: (calculation> = 2), Function CreateChain, File / Sourcecatch / PhysicsKit / PhysicsKit 6.5.4 / Fiskixkit / Box 2D / Coalition / Impact / BCHIHAP, CPPP, Line 45.

I'm trying to create a function to call a CGPath as a parameter and count the digits until it reaches 3 (or If not 3 then the end) and

thanks

If you want to calculate the elements of CGPath , then you have to use CGPathApply , and there is no one to support you all for quick termination. Elements must be calculated. Get it from my Rob_forEachElementOfCGPath function, and use it like this: 

  int numbersopsconfig (CGPathRef path) {__black int calculation = 0; Rob_forEachElementOfCGPath (Path, ^ (Const CGPathElement * element) {if (element-> Type! = KCGPathElementMoveToPoint) {++ count;}}); Calculation of return; }

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

c++ - Qt::make_shared for creating QSharedPtr as std::make_shared for creating std::shared_ptr -

-
As stated in the Barjini Stroustrup's "A Tour of C ++", and a known C ++ 14 practice As such, someone should avoid the naked code in the new and delete . Provides std :: make_shared and std :: make_unique to create smart pointers to store allocated items in the standard library. However, it is not possible to use these routines for non-standard smart pointers, such as QT's own memory management model (with parent), but also smart pointer class like Provides QSharedPointer and QPointer (although later it is not actually a brochure indicator). My question is: Is not it convenient to create Qt analog of std :: make_shared ? To like it, QSharedPtr : Namespace Qt {template & lt; Class T, squares ... Args & gt; QSharedPointer & LT; T & gt; Make_shared (erg & amp; ... args) {return QSharedPointer & lt; T & gt; (New t (std :: forward & lt; ergos & gt; (args) ...)); }} or to create this, QPointer : named place ...
