Here we will take NSMutableArray with objects and NSDictionary with Objects and Keys.
NSMutableArray* mArray = [[NSMutableArray alloc]
initWithObjects:@"A",@"B",@"C",@"D",@"E",@"F", nil];
NSMutableDictionary *mDic = [NSMutableDictionary
dictionaryWithObjectsAndKeys:@"F",@"mF",@"G",@"mG",@"B",@"mB",@"I",@"mI",nil];
We will write a Function which can provide us the array of founded keys after comparison.
-(NSMutableArray*)compareMyObject:(NSMutableArray*)array:(NSDictionary*)dic
{
NSMutableArray* keysArray = [[NSMutableArray alloc] init];
for(int k=0;k<[array count];k++)
{
NSString* mStr = [array objectAtIndex:k];
NSArray* array = [dic allKeysForObject:mStr];
if([array count])
{
[keysArray addObject:[array objectAtIndex:0]];
}
}
return keysArray;
}
Now we will call this method in the following format.
NSMutableArray* keysArray = [self compareMyObject:mArray:mDic];
The above method gives us the result array now, We will print and check those results.
NSLog(@"total %d keys found. Those are %@",[keysArray count],[keysArray description]);
The result is :
keysArray = (
mB,
mF
)
