可设置可选图片数量上限

[zld]

可能不止用于9图模式，比如想在修改头像的时候也用这个，就只需要上限为1。
使用方式如下：

- (void)preview:(UITapGestureRecognizer *)tap{
    UIView *temp = tap.view;
    JFImagePickerController *picker = [[JFImagePickerController alloc] initWithPreviewIndex:temp.tag];
    picker.maxImagesCount = 1;
    picker.pickerDelegate = self;
    [self presentViewController:picker animated:YES completion:nil];
}

- (void)pickPhotos{
    JFImagePickerController *picker = [[JFImagePickerController alloc] initWithRootViewController:nil];
    picker.maxImagesCount = 1;
    picker.pickerDelegate = self;
    [self presentViewController:picker animated:YES completion:nil];
}
