我有这个gif图片:
我可以使用以下代码添加自定义静态图片作为标记:
if let location = locationManager.location {
currentLocationMarker = GMSMarker(position: location.coordinate)
currentLocationMarker?.icon = UIImage(named: "user")
currentLocationMarker?.map = mapView
currentLocationMarker?.rotation = locationManager.location?.course ?? 0
}
我想将此gif图像用作标记。反正有吗虽然我知道鼓励使用静态图像,但是有可能吗?
我当时正在考虑添加一个UIView
说一个100x100
视图并在其中添加动画图标,虽然还没有尝试过,但是我尝试了该线程中提到的解决方案:How to load GIF image in Swift? :
let jeremyGif = UIImage.gifImageWithName("puppy")
let imageView = UIImageView(image: jeremyGif)
imageView.frame = CGRect(x: 0, y: 0, width: jeremyGif?.size.width ?? 100.0, height: jeremyGif?.size.height ?? 100.0)
//view.addSubview(imageView)
//mapView.addSubview(imageView)
if let location = locationManager.location {
currentLocationMarker = GMSMarker(position: location.coordinate)
currentLocationMarker?.icon = imageView.image //UIImage(named: "user")
currentLocationMarker?.map = mapView
currentLocationMarker?.rotation = locationManager.location?.course ?? 0
}
,但是这样做也不起作用。我已将此gif图片添加到资产中,这就是它在其中的显示方式:

我知道了。所以这是解决方案:
将此代码添加到要具有gif图像的位置。就我而言,我将其放置在用户位置:
func addCurrentLocationMarker() {
currentLocationMarker?.map = nil; currentLocationMarker = nil
let puppyGif = UIImage.gifImageWithName("Puppy")
let imageView = UIImageView(image: puppyGif)
imageView.frame = CGRect(x: 0, y: 0, width: 100, height: 100)
if let location = locationManager.location {
currentLocationMarker = GMSMarker(position: location.coordinate)
currentLocationMarker?.iconView = imageView
currentLocationMarker?.map = mapView
currentLocationMarker?.rotation = locationManager.location?.course ?? 0
} }
答案 1 :(得分:0)
感谢您的提问和回答。这里的主要思想是通过使用显示Gif图像的UIImageView覆盖GMSMarker.iconView
我将您的想法用于实现,但可能比您的答案要复杂一些,但未使用第3个库
首先,我通过此工具https://onlinepngtools.com/convert-gif-to-png将gif图像导出为png图像序列
然后,我创建可对这些PNG进行动画处理的UIImageView
UIImageView * gifImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 24, 24)];
gifImageView.animationImages = @[ [UIImage imageNamed:@"gifToPngFrame01"]
,[UIImage imageNamed:@"gifToPngFrame02"]
,[UIImage imageNamed:@"gifToPngFrame03"]
,[UIImage imageNamed:@"gifToPngFrame04"]
,[UIImage imageNamed:@"gifToPngFrame05"]
,[UIImage imageNamed:@"gifToPngFrame06"]
,[UIImage imageNamed:@"gifToPngFrame07"]
,[UIImage imageNamed:@"gifToPngFrame08"]
,[UIImage imageNamed:@"gifToPngFrame09"]
,[UIImage imageNamed:@"gifToPngFrame10"]
,[UIImage imageNamed:@"gifToPngFrame11"]
,[UIImage imageNamed:@"gifToPngFrame12"]
,[UIImage imageNamed:@"gifToPngFrame13"]];
gifImageView.animationRepeatCount = 0;
gifImageView.animationDuration = 1;
CLLocationCoordinate2D position2 = CLLocationCoordinate2DMake(21.033333, 105.87);
GMSMarker *gifMarker = [GMSMarker markerWithPosition:position2];
gifMarker.iconView = gifImageView;
gifMarker.map = mapView;
gifMarker.groundAnchor = CGPointMake(0.5, 0.5);
[mapView animateToLocation:position2];
[gifImageView startAnimating];
此代码使用目标c。但我认为这可能会使其他人对该主题有更多好处
