It's not the most beautiful way, but I guess this should work:
- (NSString *)stringOutputForDictionary:(NSDictionary *)inputDict {
NSMutableString * outputString = [NSMutableString stringWithCapacity:256];
NSArray * allKeys = [inputDict allKeys];
for (NSString * key in allKeys) {
if ([[inputDict objectForKey:key] isKindOfClass:[NSDictionary class]]) {
[outputString appendString: [self stringOutputForDictionary: (NSDictionary *)inputDict]];
}
else {
[outputString appendString: key];
[outputString appendString: #": "];
[outputString appendString: [[inputDict objectForKey: key] description]];
}
[outputString appendString: #"\n"];
}
return [NSString stringWithString: outputString];
}
