我希望能够使用 plist 来进行我在应用程序中实现的设置。我想要一个字典“Settings”来保存我的数组,例如“Debug”、“Option 1”、Option 2”等。如何访问“Settings”字典下的“Debug”数组?
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *myPlistPath = [documentsDirectory stringByAppendingPathComponent:@"ProfileManager.plist"];
NSDictionary *plistDict = [[NSDictionary alloc] initWithContentsOfFile:myPlistPath];
swDebug.on = [plistDict objectForKey:@"Debug"];
.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Current Profile</key>
<string>Sample Profile</string>
<key>Custom Profiles</key>
<array>
<dict>

<key>bluetooth</key>
<false/>

</dict>

<string>ON</string>
</dict>
</dict>
</plist>
在您的示例中, Debug 是一个字符串,而不是一个数组(这就是您在问题中所说的)。无论哪种情况,问题都是您在错误的字典中访问密钥。你有:
swDebug.on = [plistDict objectForKey:@"Debug"];
你需要:
swDebug.on = [[plistDict objectForKey:@"Settings"] objectForKey:@"Debug"];
由于设置是字典 plist 中的字典。
