使用SDWebImageView加載gif圖片

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    [self initLoadingImageView];
}

- (void)initLoadingImageView

{

    NSString  *filePath = [[NSBundle bundleWithPath:[[NSBundle mainBundle] bundlePath]] pathForResource:@"2.gif" ofType:nil];
   
    NSData  *imageData = [NSData dataWithContentsOfFile:filePath];
   
    self.loadingImageView = [[UIImageView alloc]init];
        self.loadingImageView.frame = CGRectMake(0, 0, self.view.frame.size.width,  self.view.frame.size.height);
   
    self.loadingImageView.backgroundColor = [UIColor blueColor];
    //第一種方法使用imageData加載
    self.loadingImageView.image = [UIImage sd_animatedGIFWithData:imageData];
    //第二種方法使用圖片名字加載
    //self.loadingImageView.image = [UIImage sd_animatedGIFNamed:@"2"];
   
    [self.view addSubview:self.loadingImageView];
   
    [self.view bringSubviewToFront:self.loadingImageView];
