我正在尝试从 PSSwitchCell 读取 BOOL 值,但 BOOL 始终为 true。这是我的代码( Logo 调整(iOSopendev))

这是 .xm 文件,我使用 iosopendev Logo 调整模板和简单的首选项加载器。

另外,我知道这只是一个简单的调整,但我正在学习这一切是如何工作的。我看过在线教程,但我似乎不明白为什么这不起作用。

#import <UIKit/UIKit.h>
#define plist_path @"/Library/PreferenceLoader/Preferences/MyTweak.plist"

#define listenToNotification$withCallBack(notification, callback);CFNotificationCenterAddObserver(CFNotificationCenterGetDarwinNotifyCenter(), NULL, (CFNotificationCallback)&callback, CFSTR(notification), NULL, CFNotificationSuspensionBehaviorHold);
%hook SBApplicationIcon

+ (id)sharedInstance
{
%log;

return %orig;
}

static NSMutableDictionary *plistDict = nil;
static void loadSettings(void) {
if (plistDict) {
[plistDict release];
plistDict = nil;
}
plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:plist_path];

}
-(void)launch
{
NSString *number = [[[plistDict objectForKey:@"enabled"] intValue];

if ([number isEqualto:@"1"]) {
NSString *appName = [self displayName];
NSString *message = [NSString stringWithFormat:@"The app %@ has been launched", appName, nil];
UIAlertView *alert1 = [[UIAlertView alloc] initWithTitle:appName message:message delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
alert1.delegate = self;
[alert1 show];
[alert1 release]; }
else {
//Do nothing!
}
%orig;
}

- (void)messageWithNoReturnAndOneArgument:(id)originalArgument
{
%log;

%orig(originalArgument);

// or, for exmaple, you could use a custom value instead of the original argument: %orig(customValue);
}

- (id)messageWithReturnAndNoArguments
{
%log;
id originalReturnOfMessage = %orig;

// for example, you could modify the original return value before returning it: [SomeOtherClass doSomethingToThisObject:originalReturnOfMessage];

return originalReturnOfMessage;
}

%end
%ctor {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
%init;
listenToNotification$withCallBack("dylankelly.MyDev.MyTweak-preferencesChanged", loadSettings);
loadSettings();
[pool drain];
}

这是我的 plist(其中一部分)文件,它显示在设置中。

<dict>
<key>cell</key>
<string>PSSwitchCell</string>
<key>default</key>
<integer>0</integer>
<key>defaults</key>
<string>dylankelly.MyDev.MyTweak</string>
<key>TrueValue</key>
<integer>1</integer>
<key>FalseValue</key>
<integer>0</integer>
<key>key</key>
<string>enabled</string>
<key>label</key>
<string>Show</string>
<key>PostNotification</key>
<string>dylankelly.MyDev.MyTweak-preferencesChanged</string>

</dict>

最佳答案

您不能将 BOOL 存储在 plist 或字典中,因为它不是对象。将您的值保存为 NSNumbers; @(0) 表示 false,@(1) 表示 true。

您可以将以下数据类型作为值存储在 .plist 文件中:

-NSArray 
-NSMutableArray
-NSDictionary
-NSMutableDictionary
-NSData
-NSMutableData
-NSString
-NSMutableString
-NSNumber
-NSDate
