// 感覺應該是用排序的邏輯，desc:前面的比較大 // true: date1 大於 date2 BOOL result = [date1 compare:date2] == NSOrderedDescending; // true: date1 小於 date2 BOOL result = [date1 compare:date2] == NSOrderedAscending; // true: date1 等於 date2 BOOL result = [date1 compare:date2] == NSOrderedSame; // true: date1 大於等於 date2 BOOL result = [date1 compare:date2] == NSOrderedDescending || [date1 compare:date2] == NSOrderedSame;

  問題描述︰ 原URL可以在iPhone中直接打開APP 但在iPad中卻會打開Safari再打開AppStore，而沒有直接打開APP   看了該URL的網頁源始碼後發現他使用了 browser-deeplink 但卻只會打開AppStore   HTML裡面寫法類似 這裡 寫的問題 但用Schema似乎會有問題，解決辦法應該是用通用鏈接，如下 iOS9 Universal Links （通用鏈接）   未完待續…

1.「Product」->「Scheme」->「Edit Scheme」，切到「Run」分頁，將「Build Configuration」切換為「Release」。 2a. 分別build出simulator lib and iphone lib，再執行合併程式 lipo -create $(PATH_TO_libMZKit-iphonesimulator.a) $(PATH_TO_libMZKit-iphoneos.a) -output libMZKit.a 2a. Add Run Script # define output folder environment variable UNIVERSAL_OUTPUTFOLDER=${BUILD_DIR}/${CONFIGURATION}-universal Step 1. Build Device and Simulator versions xcodebuild -target TargetName ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphoneos BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" xcodebuild -target TargetName ONLY_ACTIVE_ARCH=NO -configuration ${CONFIGURATION} -sdk iphonesimulator BUILD_DIR="${BUILD_DIR}" BUILD_ROOT="${BUILD_ROOT}" make sure the output directory exists mkdir -p "${UNIVERSAL_OUTPUTFOLDER}" Step 2. Create universal binary file using lipolipo -create -output "${UNIVERSAL_OUTPUTFOLDER}/lib${PROJECT_NAME}.a" "${BUILD_DIR}/${CONFIG...

使用Doxygen: 安裝 from: http://www.stack.nl/~dimitri/doxygen/download.html If you have GIT installed, you should do the following to get the initial copy of the repository: git clone https://github.com/doxygen/doxygen.git cd doxygen After that you can use mkdir build cd build cmake -G "Unix Makefiles" .. make To force a fresh build after an earlier check-out simple remove the build directory and redo the steps above. After the binaries have been built, you can use make install to install them. 使用 1 產生設定檔 doxygen -g ProjectNameConfig 2 修改設定 PROJECT_NAME = OpenCV 2.4.9 # 改成自己要的專案名字 PROJECT_NUMBER = 1.0 # 專案的版本 OUTPUT_DIRECTORY = ../docs/OpenCV2.4.9 # 輸出的位置 INPUT = /usr/local/Cellar/opencv/2.4.9 # 讀取的位置 CREATE_SUBDIRS = YES OUTPUT_LANGUAGE = Chinese-Traditional FULL_PATH_NAMES = NO EXTRACT_STATIC = YES FILE_PATTERNS = *.h *.m *.swift #讀進的副檔名, 不需要逗號 RECURSIVE = YES REFERENCED_BY_RELATION = YES REFERENCES_RELATION = YES INLINE_SOURCE = YES EXTRACT_ALL = YES 3 支援繪圖 安裝Graph...

xcode 複製專案並修改專案名稱 1.將專案copy到新的folder下(OLD->NEW) 2.用xcode打開OLD.xcodeproj 3.將專案名稱點兩下直接改名，改完後clean and close 4.回到NEW目錄下將所有的資料夾及檔案名稱全改成NEW 5.對NEW.xcodeproj顯示套件內容，用xcode打開project.pbxproj，將所有的OLD換成NEW 6.到manager schemes修改scheme名稱 搞定 ！
