Mountain Lion 下的 Xcode 4.4 是不是没法跑 iOS 4.3 的模拟器?

嗯，确实是没法用了。
我打开
~/Library/Caches/com.apple.dt.Xcode/Downloads/eded78df8bfabaf6560841d10cf8e53766f74f28.dvtdownloadableindex

然后发现
<dict>
<key>source</key>
<string>http://adcdownload.apple.com/ios/ios_simulator__resigned/ios_43_simulator.dmg</string>
<key>identifier</key>
<string>Xcode.SDK.iPhoneSimulator.4.3</string>
<key>name</key>
<string>iOS 4.3 Simulator</string>
<key>userInfo</key>
<dict>
<key>InstalledIfAllPathsArePresent</key>
<array>
<string>$(DEVELOPER)/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk</string>
</array>
<key>ActivationPredicate</key>
<string>$MAC_OS_X_VERSION < "10.8.0"</string>
</dict>
</dict>

其中有一句<key>ActivationPredicate</key> <string>$MAC_OS_X_VERSION < "10.8.0"</string>

但是如果我修改了这句话也还是不行，一旦打开xcode这个文件就会被修改回去（貌似是被替换成别的）

I've looked into it, and this is a deliberate behavior from Apple.

Here is an (edited) extract of the cache for Xcode download locations:

~/Library/Caches/com.apple.dt.Xcode/Downloads/eded78df8bfabaf6560841d10cf8e53766f74f28.dvtdownloadableindex

<dict>
<key>source</key>
<string>http://adcdownload.apple.com/ios/ios_simulator__resigned/ios_43_simulator.dmg</string>
<key>identifier</key>
<string>Xcode.SDK.iPhoneSimulator.4.3</string>
<key>name</key>
<string>iOS 4.3 Simulator</string>
<key>userInfo</key>
<dict>
<key>InstalledIfAllPathsArePresent</key>
<array>
<string>$(DEVELOPER)/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk</string>
</array>
<key>ActivationPredicate</key>
<string>$MAC_OS_X_VERSION < "10.8.0"</string>
</dict>
</dict>
Note the explicit "ActivationPredicate: $MAC_OS_X_VERSION < 10.8.0" setting, which is not present on other simulator packages.

I tried to edit the file, but it is replaced by another version as soon as Xcode opens. And I couldn't manage a manual download of the 4.3 Simulator DMG: the ADG website throws a "Session expired" error.

Looks like Apple had issues with the 4.3 simulator, and decided to disable it. Which sucks for people that have to support this version.

也就说,山狮系统中无法使用4.3模拟器..楼上翻译的还行.大概意思都出来了.
