How to convert UIImage to NSData when the image's type is gif?

Question

I've searched for so much articles about converting UIImage to NSData.There are some solutions.But when I only know the (UIImage*) image object , how could I configure it's NSData correctly especially when it's type is gif.

-(void)convertUIImageToNSData:(UIImage* )image{
    //if the image's type is gif,how to get it's data
    NSData *data = ?
}

Answer 1

Gif在iOS中不受支持，它将文件视为普通文件，并且也不会存储为UIImage而没有lib或其他内容，您可以使用dataWithContentsOfFile使其成为NSData

Answer 2

Finally, I got the nsdata of an image by pass the original data when I just pick an picture from system album. That's little not so elegant.
