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।

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...

Matlab: Transfer variable from GUI to Base Workspace and new Variables (Static Workspace, Script, Creating new Variables) -

-
I am developing a GUI for the current script, which expects some straight values ​​in the base workspace. The GUI will move users' values ​​to the base-workspace and then the script will start and close itself immediately. It sounds very easy and has values ​​that run with Essenin and Evelyn, but I work for days with the problem that if the script takes the values ​​of my post, then I get a message: Try to add var_name View MATLAB programming for static workspace details, see restrictions on assigning at variables. What's the problem? The GUI is closed and the script will use the base-workspace without restriction. How can this be done? The script is untouchable (not mine) and this base expects variables in the workspace, so the GUI is moving the value in the workspace and nothing else. A stable workspace is not required Workspaces will be free of any restrictions. To summarize: I want to delete "Static" in the "static workspace" Specifies the...
