问题描述
虽然我完成了一个应用程序内购买应用程序，并且在iPad / Iphone上进行了几次测试后，每件事都很好，桌面视图的单元格及其高度的图像与代码中写的一模一样，所以我上传了应用程序当它被处理到app Store时，我下载它，IPhone / IPad中的表视图单元格的大小都比测试时设置的大小大得多，因此单元格中的图像就像拉伸!!!!不清楚，我试着直接通过xcode测试它到我的设备，它几乎和以前一样好，但问题是只有从商店下载时，
While i finished developing an in-app-purchase application, and after several testing on iPad/Iphone, every thing was fine, the images of table view's cells and its hight was exactly as wrote in code, so i upload the application, when it was processed to the app Store, i download it, the table view cells in both IPhone/IPad were in different sizes much bigger size then that was set while testing,so the image in cells was like stretched!!!!and not clear, i tried to test it then directly via xcode to my device, it was almost fine as before, but the problem is only when downloading from store,
我真的感谢任何帮助，
I really appreciate any help,
问候，
推荐答案
这很可能与浮点计算优化有关。
This is quite likely to be do with floating-point calculation optimization.
w ^ hen build for release，默认情况下，Xcode将尝试完全优化您的代码，包括使您的浮点计算更有效。但是，有时它们可能会被错误地优化，这可能会导致重大问题，尤其是视图的定位/大小调整等。
When building for release, by default, Xcode will try to fully optimize your code, including making your floating-point calculations more efficient. However, sometimes they can be incorrectly optimized, and this can cause major issues especially with positioning / sizing of views etc.
对我来说，这是在构建发布版+ armv6时发生的架构，我之前已经（仅在发布时才实现）。
For me, this happens when building for release + armv6 architecture, and I've had exactly the same problem (only realized when released) before.
值得庆幸的是，有一种方法可以禁用浮点优化。方法如下：
Thankfully, there is a way to disable the floating-point optimizations. Here's how:
使用LLVM GCC 4.2
- 单击左侧文件窗格中的项目
- 单击
目标下的项目名称（如下所示），然后单击构建设置。 - 在右侧的搜索框中搜索thumb
- 您应该看到一个名为Compile for的设置ThumbunderLLVM GCC 4.2 - 代码生成。如果你不这样做，那是因为你正在使用Apple LLVM编译器3.0（下面的说明）。
- 将鼠标悬停在Release上，然后点击加号图标。
- 应该出现一个新选项，通过下拉菜单从下拉列表中选择ARMv6。
- 然后为该选项选择否。它现在应该如下所示：
- Click on your project in the files pane on the left
- Click the project name under
Targets(as seen below), then click "Build Settings". - Search for "thumb" in the search box on the right hand side
- You should see a setting called "Compile for Thumb" under "LLVM GCC 4.2 - Code Generation". If you don't, it's because you're using the Apple LLVM compiler 3.0 (instructions for that are below).
- Hover over Release, and click the plus icon.
- A new option should appear, with a drop-down, select "ARMv6" from the dropdown.
- Then select "No" for that option. It should now look like below:
使用Apple LLVM 3.0编译器
- 按照上面的步骤1和2进行操作。
- 在搜索中搜索其他c标志 box
- 按照上述相同步骤添加ARMv6 +版本的特定配置。
- 双击带有标志的框，然后添加标志
-mno-thumb。它现在应该如下所示
- Follow steps 1 and 2 above.
- Search for "other c flags" in the search box
- Follow the same steps above to add a specific configuration for ARMv6 + release.
- Double-click the box with the flags in, and add the flag
-mno-thumb. It should now look like below
如果在此之后仍然存在发布版本问题，您可能想尝试全局禁用compile for thumb 。
If it still has issues under the release build after that, you may want to try disabling compile for thumb globally.
希望有所帮助。
