What is the cause of error by using NSPredictate?
#import "Predictate.h"

@implementation Predictate

@synthesize dictate;

-(id)init{
    if ((self = [super init])) {
    }
    return self;
}

- (void)Predictate{
    dictate = [[NSMutableArray alloc]initWithObjects:@"AAA",@"BBB",@"CCC", nil];
    NSPredicate *test = [NSPredicate predicateWithFormat:@"dictate like 'AAA'"];

    NSMutableArray *result = [dictate filteredArrayUsingPredicate:test];

    NSLog(@"%@",result);
}

-(void)dealloc{
    [dictate release];
    [super dealloc];
