iPhone Core Data problem
- by Junior B.
This is my first project with Core Data, I followed the Event tutorial provided by Apple that helped me to understand the basic of core data in iPhone.
But now, working over my project, I've a problem adding data into my database.
When i create an object and set the data, if I try to get it back, the system returns me a strange sequence of characters.
This is what i see in log if I try to log it:
2010-05-11 00:16:43.523 FG[2665:207] Package: ‡}00å
2010-05-11 00:16:43.525 FG[2665:207] Package: ‡}00å
2010-05-11 00:16:43.526 FG[2665:207] Package: ‡}00å
2010-05-11 00:16:43.527 FG[2665:207] Package: ‡}00å
2010-05-11 00:16:43.527 FG[2665:207] Package: ‡}00å
2010-05-11 00:16:43.527 FG[2665:207] Items: 5
What kind of problem could be this?
Edit:
This is the part of the code that generate the error:
package = (Package *)[NSEntityDescription insertNewObjectForEntityForName:@"Package" inManagedObjectContext:moc];
theNodes = [doc nodesForXPath:@"//pack" error:&error];
for (CXMLElement *theElement in theNodes)
{
// Create a counter variable as type "int"
int counter;
// Loop through the children of the current node
for(counter = 0; counter < [theElement childCount]; counter++) {
if([[[theElement childAtIndex:counter] name] isEqualToString: @"id"])
[package setIdPackage:[[theElement childAtIndex:counter] stringValue]];
if([[[theElement childAtIndex:counter] name] isEqualToString: @"title"])
[package setPackageTitle:[[theElement childAtIndex:counter] stringValue]];
if([[[theElement childAtIndex:counter] name] isEqualToString: @"category"])
[package setCategory:[[theElement childAtIndex:counter] stringValue]];
if([[[theElement childAtIndex:counter] name] isEqualToString: @"lang"])
[package setLang:[[theElement childAtIndex:counter] stringValue]];
if([[[theElement childAtIndex:counter] name] isEqualToString: @"number"]) {
NSNumberFormatter * f = [[NSNumberFormatter alloc] init];
[f setNumberStyle:NSNumberFormatterDecimalStyle];
NSNumber * myNumber = [f numberFromString:[[theElement childAtIndex:counter] stringValue]];
[f release];
[package setNumber:myNumber];
}
}
}
NSLog([NSString stringWithFormat:@"=== %s ===\nID: %s\nCategory: %s\nLanguage: %s",[package packageTitle], [package idPackage] ,[package category],[package lang]]);
