日志似乎表明问题来自 libz.1.2.3.dylib 框架。
您使用什么 iOS SDK（以及哪个 Xcode 版本）？
在您的项目中，单击您的目标并转到“构建阶段”选项卡，然后转到“将二进制文件与库链接”部分。
尝试删除 libz.1.2.3 框架，然后重新添加 libz.1.2.5（单击窗口底部的小“+”并从列表中选择 libz.1.2.5）。
编辑：
正如 Abizern 在下面的评论中所述，添加 libz.dylib 而不是 libz.1.2.5.dylib 应该可以解决问题。这应该链接到最新版本的库（请参阅此问题和答案 此处）。
The logs seem to indicate that the problem is coming from the libz.1.2.3.dylib framework.
What iOS SDK are you using (and which Xcode version) ?
In your project, click on your target and go to the Build Phases tab, then "Link binary with libraries" section.
Try removing the libz.1.2.3 framework and then re-adding the libz.1.2.5 (click on the little "+" at the bottom of the window and select libz.1.2.5 from the list).
EDIT:
As stated by Abizern in below comment, adding libz.dylib instead of libz.1.2.5.dylib should do the trick. This should link to the latest version of the lib (see this question and answers here).
