Slow load time for custom UIView in Swift

阅读更多关于 Slow load time for custom UIView in Swift

问题 Background In order to make a text view that scrolls horizontally for vertical Mongolian script, I made a custom UIView subclass.

The purpose of sticking everything in a parent UIView is so that Auto layout will work in a storyboard. (See more

Custom font displays in IB but not in simulator

问题 I have set up a UITextView and a UILabel to use a custom font. (It is a vertically mirrored Mongolian font, but I also included English text so that you can see the effect.) The words display in the Interface Builder, but in the simulator most of the characters in the UITextView are just empty boxes. Strangely, in the characters in the UILabel do display correctly in the simulator. How do I get them to display in the UITextView as well? Notes: I am using Xcode version 6.3.2. From this SO Q&A

问题 Background I'm new to iOS development, but in order start making even the most rudimentary apps using the vertical Mongolian script, I need to have a vertical UITextView . I haven't found any other Mongolian app developers sharing their code so I am trying to make it myself.

问题 How do you make vertical (with left-to-right line wrapping) Mongolian script TextViews for Android apps? Background Android has fairly good support for many of the world's languages, even RTL languages like Arabic and Hebrew. However, there is no built in support for top-to-bottom languages like traditional Mongolian (which is still very much alive in Inner Mongolia and not to be confused with Cyrillic Mongolian). The following graphic shows the text direction with English added for clarity.

问题 I am making a vertical EditText for traditional Mongolian. I have successfully implemented it by embedding a slightly modified EditText inside of a rotated ViewGroup . I need to create a completely custom context menu because the system one does not support vertical text and is also not rotated when the ViewGroup is rotated. So I want to disable the system context menu altogether. Note that this is different than these questions that are just trying to disable copy/paste/etc.: How to disable

问题 Explanation of what I am trying to do I'm making a custom in-app keyboard that works on the same principle of this example. However, in my keyboard I'm using popup windows to display extra letter forms. In traditional Mongolian letters have different forms depending on if they are located at the beginning, middle, or end of a word. Usually these can be determined from the context, but sometimes a user needs to choose an alternate form explicitly from the popup key candidates. Lets say that a

Supporting complex text layout with OpenType fonts in Android

阅读更多关于 Supporting complex text layout with OpenType fonts in Android

What I would like I would like to put an OpenType font in my assets folder and use Typeface.createFromAsset to render Unicode text in my Android application for a language that uses complex text layout (CTL) . Background I want to do this for traditional Mongolian script , but it is the same issue (so I hear) for other languages like Thai, Arabic, Indic languages, and many minority languages. An OpenType font already includes the information necessary to properly display the text. The problem is that not all software supports OpenType rendering. Some do , but others don't. From what I can
