IOS Autolayout change anchorPoint of view and rotate scale -

-

अगर मैं translatesAutoresizingMaskIntoConstraints सेट करता हूं, तो मैं दृश्य के परत anchorPoint, कंसोल प्रिंट बदलता हूं: एक साथ बाधाओं को संतुष्ट करने में असमर्थ। <पूर्व> सीजीपीईटी एंकर = सीपी पॉइंट मेक ((सेल्फ सोकोलएव्यूफ्रेम.size.width / 2 + self.scrollview.contentOffset.x) /self.imageview.frame.size.width, (self.scrollview.frame .size.height / 2 + self.scrollview.contentOffset.y) /self.imageview.frame.size.height); self.imageview.layer.anchorPoint = लंगर; Self.imageview.layer.position = सीपी पॉइंटमेक (self.scrollview.frame.size.width / 2 + self.scrollview.contentoffset.x, self.scrollview.frame.size.height / 2 + self.scrollview.contentOffset.y) ; CGAffineTransform transform = CGAffineTransformMakeRotation ((slider.value * 100/180)); self.imageview.layer.transform = CATransform3DMakeAffineTransform (बदलना);

इस तरह से कोड मैं इसे छवि व्यू एक बिंदु के आसपास घुमाने के लिए इसका उपयोग नहीं कर सकता ????

मेरे पास एक और सवाल है जब मैं ऑटो लेआउट का उपयोग करता हूं, तो मैं फ़्रेम को सीधे बदल नहीं सकता। मुझे बाधा को बदलना होगा क्या मैं अपने दृश्य को पुराने कोड का उपयोग नहीं कर सका?

  1. आप स्वत: लेआउट अपनाने के बाद, आपको हमेशा बजाय फ्रेम की बाधाओं को संशोधित करें आप अपने दृश्य को पुराने फ्रेम संशोधित कोड के साथ नहीं सजीव कर सकते हैं।

  2. मेरी सिफारिश हमेशा सेट की जाती है translatesAutoresizingMaskIntoConstraints से नहीं और सेट अप करें कोड या xib के माध्यम से आपकी बाध्यता।

I'm trying to call the Python using the Java program py4j . I've been installing the plug-in Eclipse and test name Piidvi project.

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 ...
