让自己定义的变量显示在属性面板上
根据Lable内容动态获取高度
[msg.text boundingRectWithSize:CGSizeMake(200, CGFLOAT_MAX) options:NSStringDrawingUsesLineFragmentOrigin attributes:@{ NSFontAttributeName : TEXT_FONT } context:nil].size;

加载HUD耗时
- (void)showHUD:(NSString *)HUDString {
[SVProgressHUD showErrorWithStatus:HUDString];
dispatch_async(dispatch_get_global_queue(0, 0), ^{
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[SVProgressHUD dismiss];
});
});
}
