iOS實現連拍功能

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)selectedImage editingInfo:(NSDictionary *)editingInfo {
    NSData *data;
    if ([UIImagePickerController isSourceTypeAvailable:
        UIImagePickerControllerSourceTypePhotoLibrary])  {
        // Set source to the Photo Library
        picker.sourceType =UIImagePickerControllerSourceTypePhotoLibrary;
        if (selectedImage) {
            // save image
        }
        if (pickerController == picker)  {//這里的條件隨便你自己定義了
            //**主要就是下面這句話，會讓你繼續回到take camera的頁面
            pickerController.sourceType =    UIImagePickerControllerSourceTypeCamera; 
        } else {
            [picker dismissModalViewControllerAnimated:YES];
        }
    }
}
