如何掩盖不需要的“死店” XCode中的警告？ [英] how to mask an unwanted "Dead Store" warning in XCode?

问题描述

如何在XCode中屏蔽不需要的死店警告？这就是我有这个代码，我不认为这是一个问题，所以如果是这种情况我不想继续看到警告......（欢迎提供反馈）

How to mask an unwanted "Dead Store" warning in XCode? That is I have this code for which I don't think it's an issue, so if this is the case I don't want to keep seeing the warning...(welcome for feedback however)

代码在这里：

// Position and Size Labels in Cell
CGFloat currVertPos = 0; // Maintain lowest position, i.e. starting vertical point for next cell

// Set Position & Get back next veritical position to use
currVertPos = [self resizeLabel:_mainLabel atVertPos:currVertPos];
    currVertPos = [self resizeLabel:_mainLabel2 atVertPos:currVertPos];
    currVertPos = [self resizeLabel:_mainLabel3 atVertPos:currVertPos];
currVertPos = [self resizeLabel:self.secondLabel atVertPos:currVertPos];  // WARNING OCCURS HERE 

警告细节=存储的值currVertPosat永远不会被读取。

Warning Detail = Value stored "currVertPos" at is never read.

所以对于最后一行来说，确实不需要currVertPos，但这真的很重要，如果不是，我怎么能使警告静音？

So it's true that for the last line the "currVertPos" isn't needed, but does it really matter, and if not how can I silence the warning?

推荐答案

不，警告无关紧要;你可以简单地通过不做商店来消除它。从最后一行删除 currVertPos = ，没有什么可以提醒你的。

No, the warning doesn't matter; you can eliminate it simply by not doing the store. Delete the currVertPos = from the last line and there will be nothing to warn you about.
