问如何播放特定范围的UIImageView动画序列数组？

EN

- (void) loadAnim05 {
    cAnim = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"cof_01.png"]];
    cAnim.center = CGPointMake(78,211);
    NSMutableArray *array = [NSMutableArray array];
    for (int i = 1; i <= 35; i++) 
        [array addObject:[UIImage imageNamed:[NSString stringWithFormat:@"cof_%02d.png",i]]];
    cAnim.animationImages = array;
    cAnim.animationDuration = 1.0;
    cAnim.animationRepeatCount = 1;
    [self.view addSubview:cAnim];
    [cAnim release];
}
