iOS 把图片保存到相册,并获取图片文件名的实例

实例如下所示：

- (void)imagepickercontroller:(uiimagepickercontroller *)picker didfinishpickingmediawithinfo:(nsdictionary *)info {
 uiimage *image = [info objectforkey:uiimagepickercontrolleroriginalimage];
 if (picker.sourcetype == uiimagepickercontrollersourcetypecamera) {
  uiimagewritetosavedphotosalbum(image,self,@selector(image:didfinishsavingwitherror:contextinfo:),null);
 }
}
- (void)image:(uiimage*)image didfinishsavingwitherror:(nserror*)error contextinfo:(void*)contextinfo
{
 if (error) {
  dlog(@"图片保存失败！");
 }else{
  dlog(@"图片保存成功！");
 }
}
此方法可以把其他来源的图片也可保存到相册

 //当image从相机中获取的时候存入相册中
 //保存方法1
//  uiimagewritetosavedphotosalbum(img.image,self,@selector(image:didfinishsavingwitherror:contextinfo:),null);
//   imagedata = nil;
  
  weakself
  //保存方法2同时获取保存的相片文件名
  __blockalassetslibrary *lib = [[alassetslibraryalloc] init];
  [lib writeimagetosavedphotosalbum:img.image.cgimagemetadata:nilcompletionblock:^(nsurl *asseturl,nserror *error) {
   
   alassetslibraryassetforurlresultblock resultblock = ^(alasset *imageasset)
   {
    alassetrepresentation *imagerep = [imageassetdefaultrepresentation];
    weakself.imagename = [nsstringstringwithformat:@"%@",[imagerepfilename]];
    nslog(@"[imagerep filename 1] : %@", [imagerepfilename]);
    dblog(@"self.addressimagename照相0 = %@",weakself.imagename);
    commitblock(img.image,uiimagejpegrepresentation(img.image,0.5),self.imagename);
   };
   alassetslibrary* assetslibrary = [[alassetslibraryalloc] init];
   [assetslibrary assetforurl:asseturlresultblock:resultblock failureblock:nil];
   
   nslog(@"asseturl = %@, error = %@", asseturl, error);
   lib = nil;
   
  }];
  
 }];
