在使用app时，从相册中选取图片作为头像是很常用的操作，首先打开相册选择图片，然后将图片保存至本应用的document，最后将document中图片的路径保存至NSUserDefaults和服务器。

从相册中选取图片或拍照

//从相册中选取图片或拍照

  UIImagePickerController *picker = [[UIImagePickerController alloc] init]; 
  picker.delegate = self; 
  picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
  picker.allowsEditing = YES; 
  [self presentViewController:picker animated:YES completion:NULL]; 
} 
 
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { 
   
  _avatar = info[UIImagePickerControllerOriginalImage]; 
 
  [self saveImage:_avatar WithName:@"userAvatar"]; 
 
  //处理完毕，回到个人信息页面 
  [picker dismissViewControllerAnimated:YES completion:NULL]; 
  [_tableView reloadData]; 
} 

保存图片 

//保存图片 
- (void)saveImage:(UIImage *)tempImage WithName:(NSString *)imageName 
{ 
  NSData* imageData = UIImagePNGRepresentation(tempImage); 
  NSString* documentPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; 
  NSString* totalPath = [documentPath stringByAppendingPathComponent:imageName]; 
   
  //保存到 document 
  [imageData writeToFile:totalPath atomically:NO]; 
   
  //保存到 NSUserDefaults 
  NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; 
  [userDefaults setObject:totalPath forKey:@"avatar"]; 
   
  //上传服务器 
  [[HSLoginClass new] uploadAvatar:totalPath]; 
}
