Question

我试图从PSSwitchCell读取BOOL值，但BOOL一直都是真实的。这是我的代码（logo tweak（iOSopendev））

这是.xm文件，我使用iosopendev徽标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。我已经在线查看了教程，但我似乎无法理解为什么这不起作用。

#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（它的一部分）文件，显示在设置中。

<dict>

        <string>Show</string>
        <key>PostNotification</key>
        <string>dylankelly.MyDev.MyTweak-preferencesChanged</string>

</dict>

您不能将BOOL存储在plist或词典中，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存储为.plist文件中的值：

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

从Preference Bundle中读取BOOL值
