Plist in reverse order - iphone

Question

I have Plist with list with List of Dictionaries(item0,item1,item2)..
generally when I display in screen ..it populates in ascending order...item0 then item1 then item2......and so on..I want the Plist to be display in reverse order as itemn,itemn-1.........item2,item1,item0
.
and this is how code goes...and How Can I reverse it ..need changes in Array below
NSMutableArray *Array=[NSMutableArray arrayWithArray:[self readFromPlist]];
NSMutableArray *items = [[NSMutableArray alloc] init];
for (int i = 0; i< [Array count]; i++)
//how to reverse by making changes here
//for (int i =[Array count] ; i>0; i--) does not work
{
id object = [Array objectAtIndex:i];
if ([object isKindOfClass:[NSDictionary class]])
{
NSDictionary *objDict = (NSDictionary *)object;
tempItemi =[[ECGraphItem alloc]init];
NSString *str=[objDict objectForKey:#"title"];
NSLog(#"str value%#",str);
float f=[str floatValue];
//my code here
}

Answer 1

Use reverse enumeration
for (id someObject in [myArray reverseObjectEnumerator]){
// print some info
NSLog([someObject description]);
}
For your code:
for (id object in [Array reverseObjectEnumerator]){
if ([object isKindOfClass:[NSDictionary class]])
{
NSDictionary *objDict = (NSDictionary *)object;
tempItemi =[[ECGraphItem alloc]init];
NSString *str=[objDict objectForKey:#"title"];
NSLog(#"str value%#",str);
float f=[str floatValue];
//my code here
}
}
Also in your code:
//for (int i =[Array count] ; i>0; i--) does not work
should be as
for (int i =[Array count]-1 ; i>=0; i--)

Answer 2

You are itrating from count to 1 whereas array has objects from index count-1 to 0
e.g.
Array with 10 objects has objects from index 0 to 9
for (int i =[Array count]-1 ; i >= 0; i--)
{
id object = [Array objectAtIndex:i];
if ([object isKindOfClass:[NSDictionary class]])
{
NSDictionary *objDict = (NSDictionary *)object;
tempItemi =[[ECGraphItem alloc]init];
NSString *str=[objDict objectForKey:#"title"];
NSLog(#"str value%#",str);
float f=[str floatValue];
//my code here
}
