我只想在设置文件中输出我的ios应用程序的版本号。
我知道我必须将设置文件添加到应用程序文件夹中。
当我构建并运行时,我可以看到标准的settings-bundle附带的4个设置。
为了获得一个简单的只读字符串,我将第二个值更改为以下值

在代码(didFinishLaunchingWithOptions:)中,我调用以下代码:
NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
[[NSUserDefaults standardUserDefaults] setValue:version forKey:@"version_number"];
[[NSUserDefaults standardUserDefaults] synchronize];令我惊讶的是,什么也没发生。我只看到Group元素、toogle开关和滑块,但没有看到标题行。有人知道我错过了什么吗?
非常感谢!

好吧,我也有这个问题。解决方案(某种程度上)是提供一个缺省值字段,并给它一个值。这实际上是在文档中明确规定的--默认值是Title属性的必填字段,所以如果您不指定它,标题将不会显示在设置窗格中。不幸的是,一旦设置了值,我似乎就不能再更改它,可能也是按照设计的那样--文档还指出它是一个只读属性。我要尝试的解决方案是在每次创建新构建时显式地将版本号放在Root.plist文件中。超级不理想,但我认为会行得通。
编辑:检出this post on updating version number in settings bundle
编辑:好的,我把这篇文章写好了(感谢上面的那篇文章,还有一些关于bash脚本的小技巧,我对bash脚本几乎没有什么经验)。以下是脚本(我刚刚在“Run script”构建阶段内联编写了该脚本):
#!/bin/bash
builtInfoPlistPath=${TARGET_BUILD_DIR}/${INFOPLIST_PATH}
#increment the build number
buildNumber=$(/usr/libexec/PlistBuddy -c "Print :CFBundleVersion" "$builtInfoPlistPath")
buildNumber=$(($buildNumber + 1))
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$builtInfoPlistPath"
#compose the version number string
versionString=$(/usr/libexec/PlistBuddy -c "Print :CFBundleShortVersionString" "$builtInfoPlistPath")
versionString+=" ("
versionString+=$(/usr/libexec/PlistBuddy -c "Print :CFBundleVersion" "$builtInfoPlistPath")
versionString+=")"
#write the version number string to the settings bundle
#IMPORTANT: this assumes the version number is the first property in the settings bundle!
/usr/libexec/PlistBuddy -c "Set :PreferenceSpecifiers:0:DefaultValue $versionString" "Settings.bundle/Root.plist"..。就是这样!就像一种护身符!希望这对你的问题有所帮助,因为它解决了我的问题。现在唯一的问题是内部版本号有一个细微的差异...
编辑:...我用vakio's second comment on this post修复了这个问题,它将info.plist的路径设置为已经处理过的路径(在运行脚本阶段之前!)
编辑:这是我的最新版本,它在一个外部文件中,在增加内部版本号之前验证一些源文件是否已经更改:
#!/bin/bash
#note: for simplicity, it's assumed that there's already a bundle version (which is an integer) and a version string. set them in the Summary pane!
#get path to the BUILT .plist, NOT the packaged one! this fixes the off-by-one bug
builtInfoPlistPath=${TARGET_BUILD_DIR}/${INFOPLIST_PATH}
echo "using plist at $builtInfoPlistPath"
modifiedFilesExist=false
#this is the modification date to compare to -- there's a possible bug here, if you edit the built plist directly, for some reason. probably you shouldn't do that anyways.
compModDate=$(stat -f "%m" "$builtInfoPlistPath")
for filename in *
do
modDate=$(stat -f "%m" "$filename")
if [ "$modDate" -gt "$compModDate" ]
then
modifiedFilesExist=true;
echo "found newly modified file: $filename"
break
fi
done
if $modifiedFilesExist
then
echo "A file is new, bumping version"
#increment the build number
buildNumber=$(/usr/libexec/PlistBuddy -c "Print :CFBundleVersion" "$builtInfoPlistPath")
echo "retrieved current build number: $buildNumber"
buildNumber=$(($buildNumber + 1))
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$builtInfoPlistPath"
/usr/libexec/PlistBuddy -c "Set :CFBundleVersion $buildNumber" "$INFOPLIST_FILE"
#compose the version number string
versionString=$(/usr/libexec/PlistBuddy -c "Print :CFBundleShortVersionString" "$builtInfoPlistPath")
versionString+=" ("
versionString+=$(/usr/libexec/PlistBuddy -c "Print :CFBundleVersion" "$builtInfoPlistPath")
versionString+=")"
#write the version number string to the settings bundle
#IMPORTANT: this assumes the version number is the second property in the settings bundle!
/usr/libexec/PlistBuddy -c "Set :PreferenceSpecifiers:1:DefaultValue $versionString" "Settings.bundle/Root.plist"
else
echo "Version not incremented -- no newly modified files"

我也有同样的问题。要在Settings.bundle中显示Title属性,还需要添加"Default Value“(可以为空)。
1)右键单击Title对象(在我的示例中是Item 0),然后选择Add Row。
2)在已创建行的下拉列表中选择"Default Value“

3)在didFinishLaunchingWithOptions中,将您想要显示的值设置为NSUserDefaults,例如:
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setValue:@"0.0.1" forKey:@"appVersion"];
[defaults synchronize];结果:

你可以将设置包同步到NSUserDefaults,但奇怪的是,它一开始并不这样做。您必须首先将设置中的值检索到NSUserDefaults,然后,您在NSUserDefaults中对这些值所做的编辑将自动应用于设置包。
我引用了这个nice article。

对于你的案例来说,仅仅是为了保存你的版本,像这样的东西就可以工作了。(这个示例代码在某种程度上有点夸张,但应该更容易理解流程)
//Get the bundle file
NSString *bPath = [[NSBundle mainBundle] bundlePath];
NSString *settingsPath = [bPath stringByAppendingPathComponent:@"Settings.bundle"];
NSString *plistFile = [settingsPath stringByAppendingPathComponent:@"Root.plist"];
//Get the Preferences Array from the dictionary
NSDictionary *settingsDictionary = [NSDictionary dictionaryWithContentsOfFile:plistFile];
NSArray *preferencesArray = [settingsDictionary objectForKey:@"PreferenceSpecifiers"];
//Save default value of "version_number" in preference to NSUserDefaults
for(NSDictionary * item in preferencesArray) {
if([[item objectForKey:@"key"] isEqualToString:@"version_number"]) {
NSString * defaultValue = [item objectForKey:@"DefaultValue"];
[[NSUserDefaults standardUserDefaults] setObject:defaultValue forKey:@"version_number"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
}
//Save your real version number to NSUserDefaults
NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
[[NSUserDefaults standardUserDefaults] setValue:version forKey:@"version_number"];
[[NSUserDefaults standardUserDefaults] synchronize]; https://stackoverflow.com/questions/12932974
