Optimize your Autorelease pools with the following environment variables
NSAutoreleaseHighWaterMark
Default: 0
If set to X, autorelease pools will print a message if more than X objects accumulate in the pool
NSAutoreleaseHighWaterResolution
Default: 0
If set to Y, a message is logged for every Y objects that accumulate in the pool beyond the high-water mark (X)
Comes in handy… A build Script that wraps up the app and builds an ipa archive from it.
You should put it in a separate target (I use “Aggregate”) that depends on your main target. Name the Target “myProduct.ipa”:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 | if ( [ ${CONFIGURATION} != "Beta" ] || [ ${EFFECTIVE_PLATFORM_NAME} != "-iphoneos" ] ) ; then echo "error: Not building ipa. Select Beta configuration and Device as platform" exit 0 fi export TMP_PATH=/tmp/ipa.$RANDOM mkdir -p "$TMP_PATH/Payload" # copy app cp -R "${BUILD_DIR}/${CONFIGURATION}${EFFECTIVE_PLATFORM_NAME}/${CONTENTS_FOLDER_PATH}" "$TMP_PATH/Payload/${CONTENTS_FOLDER_PATH}" # copy artwork if [ -e "${PROJECT_DIR}/iTunesArtwork" ] ; then cp "${PROJECT_DIR}/iTunesArtwork" "$TMP_PATH" elif [ -e "${PROJECT_DIR}/Resources/iTunesArtwork" ] ; then cp "${PROJECT_DIR}/Resources/iTunesArtwork" "$TMP_PATH" fi pushd $TMP_PATH if test -e iTunesArtwork; then zip -r "${PRODUCT_NAME}.zip" Payload/ iTunesArtwork else zip -r "${PRODUCT_NAME}.zip" Payload/ fi popd rm -f "${BUILD_DIR}/${PRODUCT_NAME}" mv "$TMP_PATH/${PRODUCT_NAME}.zip" "${BUILD_DIR}/${PRODUCT_NAME}" rm -rf "$TMP_PATH" |
For a couple of build settings the use of conditions come quite handy.
To create a condition select the specific build setting and choose “Add Build Setting Condition” from the menu on the bottom left of your build settings dialog.
A good example is the setting for the Thumb instruction set on ARM processors. This brings performance increase on ARM7 but not on ARM6. Thats why you want to have it switched on only on ARM7 architectures.
If you got iPhone OS SDK 3.1.2 installed but want to compile for 3.0 don’t select 3.0 as base SDK.
Rather always select the most current version as base SDK and select the minimal version you want to be compatible with as your “Deployment Target”.
