Help/Support how to use ( if ) command After -(id)

No  One To Help Me ?

Hi 

I'm New In Theos and i want to learn how to use ( if ) command after (-(id)) for example:

NSDictionary *Mykey = [[NSDictionary alloc] initWithContentsOfFile:@"var/mobile/Library/Preferences/net.iperis.mypkg.plist"];

%hook PSUISoftwareUpdateController
-(id)init{
if([[Mykey objectForKey:@"softwareUpdate"] boolValue]){
%orig(nil);
}else{
return %orig;
}
}
%end

But Not Working , How Fix This Example ...

You can't have NSDictionary initialized as a global variable, instead you should set MyKey to null, then check to see if initialized in init()
Here's an example (Contains a few other fixes as well):

NSDictionary *Mykey = NULL;

%hook PSUISoftwareUpdateController
-(id)init {
    if (!Mykey) {
        Mykey = [NSDictionary dictionaryWithContentsOfFile:@"/User/Library/Preferences/net.iperis.mypkg.plist"];
    }

    if([[Mykey objectForKey:@"softwareUpdate"] boolValue]){
        return %orig(nil);
    }

    return %orig();
}
%end

This is my Tweak.xm

%hook PSUISoftwareUpdateController
-(id)init {
    if (!Mykey) {
        Mykey = [NSDictionary dictionaryWithContentsOfFile:@"/User/Library/Preferences/net.iperis.mypkg.plist"];
    }

    if([[Mykey objectForKey:@"softwareUpdate"] boolValue]){
        return %orig(nil);
    }

    return %orig();
}
%end

Oh, didn't see your other mistake, here you go:

NSDictionary *Mykey = NULL;

%hook PSUISoftwareUpdateController
-(id)init {
    if (!Mykey) {
        Mykey = [NSDictionary dictionaryWithContentsOfFile:@"/User/Library/Preferences/net.iperis.mypkg.plist"];
    }

    if([[Mykey objectForKey:@"softwareUpdate"] boolValue]){
        return nil;
    }

    return %orig();
}
%end
