iOS 11 App Development Essentials: Learn to Develop Ios 11 Apps With Xcode 9 and Swift 4

為了解決Xcode download的問題，作者Smyth, Neil 這樣論述：

iOS 11 App Development Essentials, the latest edition of this popular book series, has now been fully updated for the iOS 11 SDK, Xcode 9 and the Swift 4 programming language. This publication is available for purchase in print and Kindle editions. The print edition consists of 100 chapters and inc

ludes a free download of the color PDF of the book with 16 additional chapters. The Kindle edition contains all 116 chapters. Beginning with the basics, this book provides an outline of the steps necessary to set up an iOS development environment. An introduction to the architecture of iOS 11 and p

rogramming in Swift 4 is provided, followed by an in-depth look at the design of iOS applications and user interfaces. More advanced topics such as file handling, database management, graphics drawing and animation are also covered, as are touch screen handling, gesture recognition, multitasking, l

ocation management, local notifications, camera access and video playback support. Other features are also covered including Auto Layout, local map search, user interface animation using UIKit dynamics, Siri integration, iMessage app development, CloudKit sharing, biometric authentication, SpriteKit

games development and audio to text transcription. Additional features of iOS development using Xcode are also covered, including Swift playgrounds, universal user interface design using size classes, app extensions, Interface Builder Live Views, embedded frameworks, collection and stack layouts a

nd CloudKit data storage. The key new features of iOS 11 and Xcode 9 are also covered in detail, including Swift 4, drag and drop integration and the document browser. The aim of this book, therefore, is to teach you the skills necessary to build your own apps for iOS 11. Assuming you are ready to

download the iOS 11 SDK and Xcode 9, have an Intel-based Mac and ideas for some apps to develop, you are ready to get started.

開發一智慧型手機結合紙基晶片檢測系統用於檢測酪氨酸羥化酶缺乏症

為了解決Xcode download的問題，作者林俊毅 這樣論述：

酪氨酸羥化酶是一種關鍵酶，參與人體內酪氨酸向左旋多巴的轉化。它是一種罕見的常染色體隱性遺傳病，導致腦兒茶酚胺的缺乏，進而造成抑鬱、運動障礙和發育受損的症狀。左旋多巴是兒茶酚胺神經遞質的常見前體，因此如何快速、準確、同時測定生物基質中左旋多巴與酪氨酸的比例，對臨床診斷疾病具有重要意義。本研究利用易於取得且成本低廉的纖維素紙張，配合使用簡易的微影製程設備、材料、方法及平台，製作出一種低成本、精確、易於使用和便攜式的即時檢測系統。此系統包括一個光固化3D列印紙基微流體晶片作為反應平台，用高碘酸鈉進行表面改性以提高檢測性能、一個透過積層製造封閉外殼的檢測環境及一個 iOS APP 來驅動智慧型手機的

成像以同時量化左旋多巴、肌酐和酪氨酸。本研究透過四個實驗以測試此系統之性能：(1)為了找出替代蠟的疏水性材料，本實驗測試三種光固化樹脂，透過光固化列印圖案在紙張上，觀察樹脂在紙基晶片上的結構強度是否足夠，以及滴定化學藥品在紙基上的呈色效果是否明顯，藉此來選用最適合本研究的疏水性材料；(2)利用一次一因子實驗法，透過設定曝光時間、後固化時間和後固化溫度參數列印紙基晶片，再透過滴定化學物質顯色進行RGB分析後，建立顏色量化強度後的校正曲線，以找出製程中最佳參數；(3)在本研究設計的模具平台內建立光源環境作為系統的量測基準；(4)為了證明本研究開發系統的測量精度和準確性，與其他APP做比較。實驗結果

表明，左旋多巴、肌酐和酪氨酸可通過已建立的系統快速地定量，且具有高可靠性和可重複性，展示了一種有效常規檢查酪氨酸羟化酶缺陷患者的新工具。

Metal Programming Guide: Tutorial and Reference Via Swift

為了解決Xcode download的問題，作者Clayton, Janie 這樣論述：

Master Metal: The Next-Generation Graphics and GPU Programming Platform for Apple Developers Metal enables Apple developers to maximize performance in demanding tasks like 3D graphics, games, scientific programming, visualization, and GPU-accelerated machine learning. Metal(R) Programming Guide is t

he authoritative, practical guide to Metal for all iOS programmers who are interested in graphics programming but don't know where to start. Pioneering Apple developer Janie Clayton covers everything from basic draw calls to advanced parallel computing, combining easy-to-understand conceptual explan

ations with well-tested Swift 4/Xcode 9 sample code (available for download at GitHub). Clayton introduces the essential Metal, graphics, and math concepts every graphics programmer needs to know. She also discusses key graphics-specific libraries, concepts, and Metal Classes, presenting techniques

and examples you'll find valuable for both graphics and data processing. Clayton also provides coverage of the Metal Compute Pipeline, demonstrating practical GPU programming applications ranging from image processing to neural networking.

基於智慧手錶實作的三自由度體感遊戲控制器與其功能 - 以空間解謎虛擬實境遊戲為例

為了解決Xcode download的問題，作者黃建豪 這樣論述：

2016 年起智慧手錶在穿戴式市場中嶄露頭角，發展至今日不論是硬體的進步、使用者介面的完善，當中提供的服務越來越多也越來越豐富；智慧手錶作為一感應器豐富的穿戴設備或許在體感遊戲方面可以找到一個全新領域的發展空間。本研究的核心目的，在於協助體感裝置與虛擬實境等技術普及，使用戶能如同 Google Cardboard 利用隨手可及的設備，借助逐漸於市場普及的智慧手錶，使用者將不需額外購置裝置即可享受新科技所帶來便利及創新體驗。最終，本研究使用 ARKit 空間定位的技術在 Google Cardboard 相容裝置上製作具備六自由度的實境遊戲作品，此外搭配智慧手錶，藉由其內置的六軸陀螺儀與加速度

計、觸控螢幕等設備，做為控制訊號媒介，讓使用者可以不須額外準備控制器、搖桿等設備便能於虛擬實境中進行體感操作的遊玩體驗，提供未來相關作品一個設計的參考方向與方法。
