一、保存图片到相册
UIImage*image = [UIImageimageNamed:[NSStringstringWithFormat:@"00%d.png", i]];
UIImageWriteToSavedPhotosAlbum(image,nil,nil,nil);
二、照相、打开相册
- (void)openCamera
{
[self openImagePickerController:UIImagePickerControllerSourceTypeCamera];
}
- (void)openAlbum
{
//如果想自己写一个图片选择控制器，得利用AssetsLibrary.framework，利用这个框架可以获得手机上的所有相册图片
//UIImagePickerControllerSourceTypePhotoLibrary >UIImagePickerControllerSourceTypeSavedPhotosAlbum
[self openImagePickerController:UIImagePickerControllerSourceTypePhotoLibrary];
}
- (void)openImagePickerController:(UIImagePickerControllerSourceType)type
{
if(![UIImagePickerController isSourceTypeAvailable:type]) return;
UIImagePickerController* ipc = [[UIImagePickerControlleralloc]init];
ipc.sourceType= type;
ipc.delegate=self;
[self presentViewController:ipc animated:YES completion:nil];
}
还要实现UIImagePickerControllerDelegate的方法
#pragma mark - UIImagePickerControllerDelegate
/**
*从UIImagePickerController选择完图片后就调用（拍照完毕或者选择相册图片完毕）
*/
- (void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info
{
[picker dismissViewControllerAnimated:YES completion:nil];
//info中就包含了选择的图片
UIImage*image = info[UIImagePickerControllerOriginalImage];
//添加图片到photosView中
[self.photosView addPhoto:image];
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController*)picker
{
}
