Turning Boolean 1, 0 into a more descriptive description: NSLog(@”data1 is equal to data2: %@”, [data1 isEqualToData:data2] ? @”YES” : @”NO”);

Following situation Using TouchXML to parse XML data, works without problem on example XML files, but crahes on mine. Problem Empty values in my data set. (sometimes <place>somePlace</place>, sometimes <place></place>)

/* CXMLDocument setup & parsing omitted */
NSString *e = [[resultElement childAtIndex:counter] stringValue];
NSString *k = [[resultElement childAtIndex:counter] name];


[blogItem setObject:e forKey:k];
// crashes when e is empty. Displays a (null), is nil

Solution 1 Check for empty e, replace nil with empty string

// check if element is empty
if ( nil == e ) {	// ...or the less elegant (0 == [e length])
	e = @"";
}
[blogItem setObject:e forKey:k];

Solution 2 Use setValue instead of setObject, as setObject crashes and burns when it encounters nil, whereas setValue specifically deals only with strings and handles nil gracefully.

[blogItem setValue:e forKey:k];

Should have been clear, but was not:

NSString *s = @"aString";
s = @"anotherString";
NSLog(@"%@", s);
// anotherString

NSMutableString *m = @"aMutableString";
[m appendString:@"andAnAppendedString"];
NSLog(@"%@", m);
// aMutableStringandAnAppendedString

NString allows for the replacement of its whole content by simply assigning a new value. With NSMutableString it is possible to add/delete/insert strings at arbitrary places in a string.

After some googling, I came across this, and it seems to do the trick. add: $(SDKROOT)/ResourceRules.plist to the Code Signing Resource Path. Why exactly it’s working is anybody’s guess. ~ This might also be worth a look: liblo: Lightweight OSC implementation

What is this ** doing again? Oh yeah, thisand that.

Error message, can not compile due to Unicode characters in Source code. Watch out for Kanji spaces. Line height seems to be a bit off, if Kanji is mixed it.
