I am watching a somewhat cruel behaviour momentarily: I have a ViewController for building a View programmatically. For this purpose I have stored the names of the UILabels that will be displayed in a NSDictionary that is held in an external class which is a singleton. Unfortunately the NSDictionary is not accessible if I want to use the values in loadView. So I made some tests: The NSDictionary and its contents are availbale in init and the class is, of course, NSCFDictionary. If I have a look at it in loadView the class sometimes is NSCFDictionary and sometimes also CALayer or NSString?! I absolutely don't know what is happening??? This is the code I use:
- (id) init
{
self = [super initWithNibName:nil bundle:nil];
if (self)
{
UITabBarItem *tbi = [self tabBarItem];
[tbi setTitle:@"xxx"];
}
NSEnumerator *num = [[[ValueDispatcher dispatcher] labelDic] keyEnumerator];
NSLog(@"Class(init): %@", [[[ValueDispatcher dispatcher] labelDic] class]);
NSLog(@"No: %i", [[[ValueDispatcher dispatcher] labelDic] count]);
for (id key in num)
{
NSLog(@"Key %@ Value %@", key, [[[ValueDispatcher dispatcher] labelDic] valueForKey:key]);
}
return self;
}
- (void)loadView
{
NSLog(@"Class(loadview)1: %@", [[[ValueDispatcher dispatcher] labelDic] class]);
NSLog(@"No: %i", [[[ValueDispatcher dispatcher] labelDic] count]);
NSEnumerator *num = [[[ValueDispatcher dispatcher] labelDic] keyEnumerator];
for (id key in num)
{
NSLog(@"Key34 %@ Value %@", key, [[[ValueDispatcher dispatcher] labelDic] valueForKey:key]);
}
...
At which point between init and loadView can or will a NSDictionary be changed? Btw, another info that might be important: If I use the above code and the NSDictionary is filled by an external service everything works fine. But if I fill the NSDictionary from a stored plist during startup it fails and I watch the described behaviour...
