IOS 实现Camera连拍功能

iOS自带的照相机功能拍照之后，可以继续保留在拍照界面。

- (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)  {//这里的条件随便你自己定义了            //**主要就是下面这句话，会让你继续回到take camera的页面            pickerController.sourceType =    UIImagePickerControllerSourceTypeCamera;        } else {            [picker dismissModalViewControllerAnimated:YES];        }    }}
