UIImage के अधिकतम रिजोल्यूशन क्या है जो कि UIImageView आईओएस डिवाइस में सेट इमेज: विधि का उपयोग कर?

आप किसी भी लोड कर सकते हैं एक UIImageView में छवि के आकार के रूप में लंबे समय तक स्मृति मुक्त है लेकिन यह UIImageView नहीं है जो कि स्मृति को ले रहा है, लेकिन UIImage ।

जैसा कि ऐप्पल आपको बताता है कि निम्नलिखित में लोड नहीं होना चाहिए बड़ी छवि:

आपको UIImage ऑब्जेक्ट्स बनाने से बचना चाहिए जो कि 1024 x 1024 आकार से अधिक हैं। ऐसी छवि को बड़ी मात्रा में मेमोरी के अलावा, आप ओपनजीएल ES में बनावट के रूप में छवि का उपयोग करते समय या छवि को किसी दृश्य या परत पर चित्रित करते समय समस्याओं में चल सकते हैं। यदि आप कोड-आधारित जोड़तोड़ प्रदर्शन कर रहे हैं, तो यह आकार प्रतिबंध लागू नहीं होता है, जैसे 1024 x 1024 पिक्सल की तुलना में किसी छवि का आकार बदलकर उसे बिटमैप बैकड ग्राफिक्स संदर्भ में चित्रित करना। वास्तव में, आपको इस तरह से एक छवि का आकार बदलने की ज़रूरत हो सकती है (या इसे कई छोटे चित्रों में तोड़ सकता है) ताकि आप इसे अपने किसी विचार को आकर्षित कर सकें।

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
