Development on mobile phone，Currently popular on the network mainly two development software，Is a well-known unity (after all, the year 4399 above the game online edition of Minecraft developed by it，3d engine without any software beyond it)，Another is the relatively small minority of the cocos。cocos occupy a major position 2d game，And unity has occupied a major position 3d game。And we are talking about the same as coronasdk and cocos 2d game engine (coronasdk not been known before 2010 mainly due to charges[……]
Recently received a project，Demand is to do a special project Andrews board serial read and write in order to achieve some specific external devices to interact with - yes you read right，Andrews is also a board can have serial port!
Many friends do mobile development may not come into contact with - in fact, before I did not come into contact with。He stepped on seven or eight hours a pit，Finally climb out，Here to do a summary，Each board may project different circumstances，We must improvise。
First of all you need to know

Excellent input method，We came another excellent platform!
Although it lacks many features，But I can not wait to share these good things to you，He pocketed finally embarked on the input method macOS，over the years，Enter Larry is a nightmare in macOS，Now，This nightmare can end up。
In addition to incomplete abandoned pit I do not know when it can not be used palms input method for Mac、An outer substantially non-professionals can not be input with the Rime，You have one more choice，Pocketed input macOS version。

When developing pocketed input method，I met such a thing，That is, as a candidate bar window will go beyond the screen when the edge of the screen! and so，In the display window when I do extra check the coordinates：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
if visiableCandidateCells.isEmpty { if let screenframe = NSScreen.main?.visibleFrame { if screenframe.width < location.x + size.width { location.x -= location.x + size.width - screenframe.width } } } else { if let screenframe = NSScreen.main?.visibleFrame { if screenframe.width < location.x + self.window!.frame.size.width { location.x -= location.x + self.window!.frame.size.width - screenframe.width } } } if location.y < 50 { location.y += 35 + 35 } |
In short，That is, if you count the coordinates of their width exceeds the width of the screen，Norway put it back。
but，Such treatment does not work well in a multi-monitor，This case, since the multi display coordinate caused：

Among write off the grid input method the Mac version of the process，I encountered such a problem，Article candidate system API disrepair，Many API functions exists but is essentially useless，such as：

/*! @method @abstract Sets the "style" attributes for the candidates window. The keys for the attributes dictionary and the values are: NSFontAttributeName (value = NSFont) Setting the font attribute sets the font that is used to draw Candidates. It does not effect the selection keys which are always drawn in the same font. Note that to set the font size you should use this key/value pair. IMKCandidatesOpacityAttributeName (value = NSNumber with a float value between 0 and 1). Sets the opacity level to transparent (0.0) to completely opaque (1.0). The default opacity is 1.0. This constant is declared above. NSForegroundColorAttributeName (value = NSColor) Sets the text color used for the candidate text. By default it is black. NSBackgroundColorDocumentAttribute (value = NSColor). Set the background color that is drawn behind the candidate text. IMKCandidatesSendServerKeyEventFirst (value = NSNumber). NO (default) gives the candidate window first chance at key events. YES causes events to first be routed to the current IMKInputController. In that case, if the event is not handled, it will then be sent to the candidate window. */ open func setAttributes(_ attributes: [AnyHashable : Any]!) |
This method is used to set the style of a candidate bar，In addition to the default inside IMKCandidatesSendServerKeyEventFirst This can take effect outside，The other not ignore。

In the Swift，We often used to initialize a URL path，For example, links to web pages。For example, this：

1 2 3 4 5 6 |
…… @IBAction func goToWeb(_ sender: NSButton) { let url = URL(string: "https://v2mm.tech/category/80/logcg-input-method") NSWorkspace.shared.open(url!) } …… |
When the user clicks the button (for example, the Help button)，Then all of a sudden will help the user to open the default browser，And opens the specified page (here's a forum)。
Then，If this is your link： "https://How gracefully v2mm.tech/topic/618/ use pocketed input method dashed function" Then it is unfortunate，collapse。

China's Internet is monopoly，Most Internet users daily access are not escape those few manufacturers of service，Another point of view，They do not require services outside of these manufacturers。Because daily Internet services are monopolized by manufacturers，As an independent developer，You do not have enough human and material resources，Not thinking focus、Research does not expect users，The temerity to contend against the wind and manufacturers，So the next failure is inevitable。
Previous articleWe discussed the importance of market segmentation for independent developers，So this time we take a look，No money, no team did a designer of independent developers，How[……]

As the saying goes，A good beginning is half the battle。
I find a lot of friends to chat，He says wants independent developers，Say you have an idea or project。And so they opened their mouths，I knew he was the end result is going to vote resume。
Many independent developers from the outset doomed (more likely than others) fail。 Why do you say? Many developers try to do independent development，Finally, you find yourself doing the app with no one。Eventually leading to frustrated，Back office。
Independent developers and companies to develop different，You do independent development，Then you are a person must wear many hats，But the most essential[……]
IOS app backend server to do，It needs to be done to support the ipv6，although 6 Almost do not use in China，Unfortunately Apple is now requiring all shelves app needs to support pure ipv6 network，so，At least our server to be up and running in under an environment ipv6。

With the upgrade version of Xcode，speedMore slowly，In particular, Yiyanbuge "Whiteboard"I believe we will have problems encountered。
This is the very thing affecting development efficiency。If it is possible，Then we will Xcode cache file into memory，It should be much faster speed。(Although rmbp of ssd have a very fast，But compared to memory，Or far worse -For older machines for mechanical hard drives，Speed will be more apparent。）
