I am developing a preferencePane that makes use of a subclass of
NSMutableDictionary. My subclass (SPPowerSourceSettings) has only
three methods, which is one custom init method and a pair of "get and
set" methods. Here is the code for my custom init method:
- (SPPowerSourceSettings *) initWithSettings:(NSDictionary *)settings
sourceName:(NSString *)sourceName
{
self = [super init];
if (self != nil) {
NSDictionary *sourceSettings;
sourceSettings = [[settings objectForKey:@"Custom Profile"]
objectForKey:sourceName];
[self setDictionary:sourceSettings];
}
return self;
}
Basically what is happening is - when an instance of this class is
created, System Preferences.app (the host app) hangs. If I comment
out the "[self setDictionary:sourceSettings];" line, then it doesn't
hang. I have narrowed it down through extensive testing to the fact
that if I try and add an object (or an entire dictionary) to the
SPPowerSourceSettings instance then preferencePane hangs instantly. I
am able to press "Show All" in System Preferences.app, so it doesn't
really crash as such, it just hangs there.
My instances of SPPowerSourceSettings are called acSettings,
batterySettings and upsSettings. Is there some naming convention when
it comes to preferencePanes that could be causing a naming conflict?
Is there any other conventions that I should've followed? I have
already named all of my own classes as SPxxxx to avoid class name
conflicts....
Thanks in advance,
Nick
