Status:Closed Resolved:NO
Product:MacOSX SDK Product Version:10.8
Classification:Other Bug Reproducible:Always
 
Summary:
when I use initWithDateFormat the formatter fails for some formats, when I call setDateFormat it works just fine

Steps to Reproduce:
Execute attached test case which shows the problem again

==>

//show whats wrong for bug
- (void)testParsingSimpleDateString {
	NSString *string = @"Juli 13, 2010";
	NSString *dateString = @"MMMM dd, yyyy";
	NSLocale *locale = [[NSLocale alloc] initWithLocaleIdentifier:@"de_DE"];
	NSDate *date = nil;
	
	//method a
	NSString *errorString = nil;
	
	NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
	[formatter setDateFormat:dateString];
	[formatter setLocale:locale];
	BOOL br = [formatter getObjectValue:&date forString:string errorDescription:&errorString];
	if(!br) {
		NSLog(@"%@, %@", errorString, [locale displayNameForKey:NSLocaleIdentifier value:@"de_DE"]);
		date = nil;
	} 
	else 
	{
		NSLog(@"%@", date);
	}
	GHAssert
#if TARGET_OS_IPHONE

	formatter = [[NSDateFormatter alloc] initWithDateFormat:dateString allowNaturalLanguage:NO];
	[formatter setDateFormat:dateString];
	[formatter setLocale:locale];

	} 
	else 
	{
		NSLog(@"%@", date);
	}
	
#endif

ADR: We are closing this bug since our engineers are aware of the issue, and they have determined that the issue behaves as intended. If you have questions regarding the resolution of this issue, please update your bug report with them.

me: I dont see how you could close this. the issue STILL remains and can be seen easily :) 

formatter = [[NSDateFormatter alloc] initWithDateFormat:dateString allowNaturalLanguage:NO];
[formatter setLocale:locale];
br = [formatter getObjectValue:&date forString:string errorDescription:&errorString];

and 

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:dateString];
[formatter setLocale:locale];
BOOL br = [formatter getObjectValue:&date forString:string errorDescription:&errorString];

behave differently for some date string
