使用nstimer在无限滚动视图中滑动图像

我有三个图像。它们应该像从动轮一样每4秒从右到左进行动画制作。如果用户拖动到第二张图像，那么在4秒钟后从第2 - 第3张开始滑动。如何实现这一点？使用nstimer在无限滚动视图中滑动图像

currntly我使用下面的代码，但它不按预期工作。

[NSTimer scheduledTimerWithTimeInterval:4.0 target:self selector:@selector(doAnimation) userInfo:nil repeats:YES]; 

-(void)doAnimation 
{ 

    if (currentPage) { 

     [self scrollFromCurrentpage]; 
     return; 
    } 

    //CGPoint p=CGPointMake(count*320, 0); 

    if (count==3) { 
     count=0; 

     [_scrollView setContentOffset:CGPointMake(0, 0)animated:NO]; 

     return; 
    } 


    count++; 
    [UIView animateWithDuration:2.0 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^ 
    { 
     CGRect rect= CGRectMake(count*320, 0, 320, 352); 
     [_scrollView scrollRectToVisible:rect animated:NO]; 

    }completion:^(BOOL finished) 
    { 


    }]; 
} 
-(void)scrollFromCurrentpage 
{ 

    [UIView animateWithDuration:2.0 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^ 
    { 
     CGRect rect= CGRectMake(currentPage*320, 0, 320, 352); 
     [_scrollView scrollRectToVisible:rect animated:NO]; 
     currentPage=0; 

    }completion:^(BOOL finished) 
    { 


    }]; 
}
