图片转化为数组格式代码把一张灰度图，转化为二进制的一维数组，以头文件的形式存到DSP程序中，DSP处理图像立即下载

self.gifImages=[NSMutableArray array];
NSString *path=[[NSBundle mainBundle]pathForResource:@"frontpage_refresh@2x" ofType:@"gif"];
self.gifImages=[self praseGIFDataToImageArray:[NSData dataWithContentsOfFile:path]];

_refreshImageView.image=self.gifImages[0]; _refreshImageView.animationImages=self.gifImages; _refreshImageView.animationDuration=0.85f;
_refreshImageView.animationRepeatCount=INTMAX_MAX;

//gif 转数组、
-(NSMutableArray *)praseGIFDataToImageArray:(NSData *)data;
{
    NSMutableArray *frames = [[NSMutableArray alloc] init];
    CGImageSourceRef src = CGImageSourceCreateWithData((CFDataRef)data, NULL);
    CGFloat animationTime = 0.f;
    if (src) {
        size_t l = CGImageSourceGetCount(src);
        frames = [NSMutableArray arrayWithCapacity:l];
        for (size_t i = 0; i < l; i++) {
            CGImageRef img = CGImageSourceCreateImageAtIndex(src, i, NULL);
            NSDictionary *properties = (NSDictionary *)CFBridgingRelease(CGImageSourceCopyPropertiesAtIndex(src, i, NULL));
            NSDictionary *frameProperties = [properties objectForKey:(NSString *)kCGImagePropertyGIFDictionary];
            NSNumber *delayTime = [frameProperties objectForKey:(NSString *)kCGImagePropertyGIFUnclampedDelayTime];
            animationTime += [delayTime floatValue];
            if (img) {
                [frames addObject:[UIImage imageWithCGImage:img]];
                CGImageRelease(img);
            }
        }
        CFRelease(src);
    }
    return frames;
}
