How to get array of values from NSDictionary array - ios

Question

When I try to print array of json values in log, I get addresses instead of values. Here's how I coded.
NSData *jsonData = [json dataUsingEncoding:NSASCIIStringEncoding];
NSArray *jsonArray = [NSJSONSerialization JSONObjectWithData:jsonData options:kNilOptions error:&error];
NSMutableArray *tempArray = [NSMutableArray arrayWithCapacity:jsonArray.count];
NSMutableArray *anotherTempArray = [NSMutableArray arrayWithCapacity:jsonArray.count];
NSDictionary *dict;
for(dict in jsonArray)
{
NSString *projectName = dict[#"Name"];
NSString *urlText = dict[#"Url"];
NSLog(#"Url text in array = %#", urlText);
NSString *attch = dict[#"attachmentes"];
NSLog(#"Attached url in array = %#", attch);
NSString *projID = dict[#"ProjectID"];
NSLog(#"Project ID in array = %#", projID);
SaveAttachment *saveAt = [[SaveAttachment alloc] initWithName:projectName withList:#"View" withAttachment:#"View"];
[tempArray addObject:saveAt];
SaveProjectId *saveProj = [[SaveProjectId alloc] initWithProjectId:projID];
saveProj.projectId = projID;
[anotherTempArray addObject:saveProj];
}
array = tempArray;
[self.tableViewProject reloadData];
NSLog(#"Array of project IDs === %#", anotherTempArray); //Get values (array of project ids here.
}

Answer 1

Replace
SaveProjectId *saveProj = [[SaveProjectId alloc] initWithProjectId:projID];
saveProj.projectId = projID;
[anotherTempArray addObject:saveProj];
with
[anotherTempArray addObject:projID];

Answer 2

This is because your anotherTempArray contains objects of SaveProjectId ie, everytime in for loop you are adding saveProj object not projID. Thats why your array showing SaveProjectId objects.
If you want to directly save them, then use the below modification
[anotherTempArray addObject:projID];
or you can use like(this is i would prefer)
NSLog(#"First project ID === %#", [anotherTempArray objectAtindex:0] projectId]);

Answer 3

You are storing SaveProjectId objects in the array, therefore when you print the content you see the address of those objects.

Answer 4

your "anotherTemoArray" is having objects of SaveProbectId so you have to pass object at index to SaveProjectId and then you can see the array information

Answer 5

When calling NSLog(#"Array of project IDs === %#", anotherTempArray); the -(NSString*)description method on each of the objects inside 'anotherTempArray' is being called.
In your case that means -(NSString*)description is being called on SaveProjectId objects. Override it to print out what you want... e.g.
-(NSString*)description {
return [NSString stringWithFormat:#"SaveProjectId: %#",self.projectId];
}
