javascript - Canvas setLineDash and lineDashOffset NOT resetting in iOS/Safari? -


यहाँ बेला देखें:

मेरे पीसी पर, 

  ctx.lineWidth = 20; ctx.setLineDash ([20,30]); ctx.lineDashOffset = 10; ctx.beginPath (); ctx.moveTo (150,150); ctx.lineTo (240,240); ctx.lineTo (180,40); ctx.stroke (); Ctx.closePath ()

वांछित डैश / ऑफ़सेट

अब 

  ctx के साथ लाइनों का पहला सेट देता है। setLineDash ([0,0]); कमांड के अगले बैच में ctx.lineDashOffset = 0

: 

  ctx.beginPath (); // रीसेट करता है डैश ... IOS सफारी को छोड़कर ऐसा लगता है ... ctx.setLineDash ([0,0]); ctx.lineDashOffset = 0; ctx.moveTo (0300); ctx.lineTo (0,250); ctx.lineTo (100,400); ctx.lineTo (200,300); ctx.stroke (); Ctx.closePath ()

लाइनों के पहले सेट के बाद कोई डैश गुण रीसेट करने लगता है। फिर से ठोस लाइनें प्राप्त करें

एक iPad2 चलाने वाले सफारी पर ... ऐसा लगता है कि पूरी तरह से नजरअंदाज कर दिया जाता है, लाइनें धराशायी रहती हैं। ऐसा क्यों है? इसके अलावा, क्या लाइन डैश ठीक से रीसेट करने के लिए कुछ अन्य विधि है ...?

इस संकेतन का उपयोग करें, यह सभी ब्राउज़रों में काम करेगा जो setLineDash का समर्थन करता है 

  ctx.setLineDash ([]);

ios - How to determine if NSLayoutConstraint is horizontal or vertical? -

The only way to try to make this difference is by [constraint description]; Calling and then the resulting string "V:" or "H:" I want to find this information, because of I have around 2 similar restrictions which are prototype storyboard UITableViewCell , the only difference is that supervision is horizontal Describes the distance, and the second vertical. Any suggestion would be very helpful! Edit: I accepted the reply of Grimozoar because its interpretation is a great answer and the way I am working to parse the details, @ kongtomorrow I also want to give credit, answered me here! Thanks for the help! Here is the real code that I used to find the hindrance: NSArray * constraints = [bubble constraints]; (If ([[obstacle first item]], then e-mail: message labels] and [[barrier is second int.] Is aqual: bubble] and amp; a...

c# - Reactive Extensions ControlScheduler -

Well, I'm using Reactive Extension Event Handler to handle my app events, I run the headlines on the Yuri thread. I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control. (Show this language, title, _.EventArgs.UppercaseFirst ());}); The new control scheduler (this) is not to run the code on the UI control thread, so I do not get cross threading exceptions? you should do Observable.FromEventPattern & lt; String & gt; (CC, "UiAlertMessage"). AboveOption (this). Subscribe (_ = & gt; {Alert Control. (Show this language, Titles, _.EventArgs.UppercaseFirst ());}); This is the standard way of sending a scheduler related to specific controls. Passing control scheduler as you have got subsc...
