Hi,
Question about registering defaults - I'd assumed the following would
be valid, assuming that GuideSettings implements the NSCoding protocol
- but my app doesn't like this and throws a bad access exception in
CFRetain when I run this code:
The bit that falls over is the registerDefaults: call - the stack
track being:
#0 0x96fc52d4 in CFRetain
#1 0x96f94a54 in CFDictionarySetValue
#2 0x97029dd3 in -[CFXPreferencesSource setValue:forKey:]
#3 0x9702acce in __CFXPreferencesSetValuesInSource
#4 0x9702e30d in _CFXPreferencesRegisterDefaultValues
#5 0x92b90a98 in -[NSUserDefaults(NSUserDefaults) registerDefaults:]
#6 0x000ae543 in -[DataModelDefaults init] at DataModelDefaults.m:90
- (id) init {
self = [super init];
_defs = [NSUserDefaults standardUserDefaults];
NSArray* defaultGuides = [DataModelDefaults defaultGuideSettings];
NSDictionary* defs = [NSDictionary dictionaryWithObjectsAndKeys:
defaultGuides, kGuideSettings,
[NSNumber numberWithFloat:2],
kEffectDefaultsDurationSeconds,
0];
// this goes BOOOOOM
[_defs registerDefaults:defs];
return self;
}
+ (NSArray *) defaultGuideSettings {
// simply return a list of the guide objects we want to have as
defaults
NSMutableArray* array = [[NSMutableArray new] autorelease];
[array addObject:[GuideSetting guideSettingNamed:@"Standard" width:
640 height:480]];
[array addObject:[GuideSetting guideSettingNamed:@"Standard" width:
800 height:600]];
[array addObject:[GuideSetting guideSettingNamed:@"YouTube" width:848
height:480]];
return array;
}
Am I forgetting something? I thought as long as my object could encode/
decode itself, all would be OK - anyone know what I'm doing wrong?
Thanks
