Missing something about initialization

2009-06-12 Thread Alfonso Ortega 
I'm trying to parse a bit of html and use it to initialize an object.  
I have very little background in objective-c, everything parses  
correctly, I just can't seem to get the object initialized. What am I  
doing wrong?



-(id)initWithNavcenRow:(NSString *)row
{
NSScanner *rowScanner = [NSScanner scannerWithString:row];
NSString *svnString;
NSString *prnString;
NSString *slotString;
	[rowScanner scanUpToCharactersFromSet:[NSCharacterSet  
capitalizedLetterCharacterSet] intoString:NULL];

[rowScanner scanUpToString:@/td intoString:plane];

	[rowScanner scanUpToCharactersFromSet:[NSCharacterSet  
decimalDigitCharacterSet] intoString:NULL];

[rowScanner scanUpToString:@/td intoString:slotString];
slot = [slotString intValue];

	[rowScanner scanUpToCharactersFromSet:[NSCharacterSet  
decimalDigitCharacterSet] intoString:NULL];

[rowScanner scanUpToString:@/td intoString:svnString];
svn = [svnString intValue];

	[rowScanner scanUpToCharactersFromSet:[NSCharacterSet  
decimalDigitCharacterSet] intoString:NULL];

[rowScanner scanUpToString:@/td intoString:prnString];
prn = [prnString intValue];

	[rowScanner scanUpToCharactersFromSet:[NSCharacterSet  
capitalizedLetterCharacterSet] intoString:NULL];

[rowScanner scanUpToString:@/td intoString:block];

	[rowScanner scanUpToCharactersFromSet:[NSCharacterSet  
capitalizedLetterCharacterSet] intoString:NULL];

[rowScanner scanUpToString:@/td intoString:clock];
return self;
}

You need the [super init] stuff in there.

You're not invoking super's initializer.

Re: Missing something about initialization

2009-06-12 Thread Scott Andrew 

A couple of things:

You are not retaining your values after retrieved (slot, svn, prn,  
clock, block). These are auto released and will be released the the  
next time the pool is cleaned up. (assuming you are not using garbage  
collection).  Not sure what your class is subclassed from, but if not  
NSObject you want to a call to the super's init (or what ever the  
designated initializer is).

slot, svn, and prn are apparently integers.  They are scalar values,  
not objects, and so not subject to retain-release memory management.
