使用#pragma在Xcode中禁止“实例方法未找到”警告 [英] Using #pragma to suppress “Instance method not found” warnings in Xcode

问题描述

我想用 #pragma （在Xcode中）来压制警告：

我试过了：

  #pragma GCC diagnostic ignored-Wmissing-declarations
  

和其他几个，但没有任何作用。

什么警告会导致未找到实例方法？

编辑

这里要求的是实际的代码：

  ... 
 
如果（sampleRate> 0&&！[self isFinishing]）//< ---这里警告
 {
 return self.progress; 
} 
 
 ... 
  

构建日志输出：

  /Users/User1/Documents/Project/branch/client/Folder/CodeFile.m:26:32：{26 ：32-26：50}：warning：找不到实例方法'-isFinishing'（返回类型默认为'id'）[3] 
 if（sampleRate> 0&&！[self isFinishing]） 
 ^ ~~~~~~~~~~~~~~~~~ 
  

解决方案

请参阅： https://stackoverflow.com/a/ 34043306/89035 为#pragma压制找不到实例方法的警告。

虽然看起来真的 #pragma 解决方案不存在可以通过使用 -w 来关闭单个文件中的警告。开关。

注意：此解决方案适用于Xcode 4.2及以上版本

1. S选择目标


2. 点击Build Phases标签


3. 在Compile Sources下添加 -w
code>切换到您想要禁止警告的文件


I want to use #pragma (in Xcode) to suppress the warning:

warning: instance method '-someMethod' not found (return type defaults to 'id')

I've tried:

#pragma GCC diagnostic ignored "-Wmissing-declarations"

And several others, but nothing works.

What warning causes the "instance method not found"?

Edit

As requested here is the actual code:

...

if (sampleRate > 0 && ![self isFinishing])  //<--- Warning here
{
    return self.progress;
}

...

And the build log output:

/Users/User1/Documents/Project/branch/client/Folder/CodeFile.m:26:32:{26:32-26:50}: warning: instance method '-isFinishing' not    found (return type defaults to 'id') [3]
     if (sampleRate > 0 && ![self isFinishing])
                            ^~~~~~~~~~~~~~~~~~

解决方案

See: https://stackoverflow.com/a/34043306/89035 for a #pragma to suppress "instance method not found" warnings.

While it seem that a true #pragma solution to this does not exist turning off the warnings in individual files can be accomplished by use of the -w switch.

NB: This solution is for Xcode 4.2 and above

1. Select the target
2. Click on the "Build Phases" tab
3. Under "Compile Sources" add the -w switch to the file(s) you wish to suppress warnings on
