警告:已检索到TSD插槽10，但线程数据已被删除

Question

我没有找到关于这个错误的任何东西...你知道这是从哪里来的吗？

Warning: TSD slot 10 retrieved but the thread data has already been torn down.
Warning: TSD slot 10 set but the thread data has already been torn down.

不确定如何调试此错误。不确切地知道警告发生在哪里。

我在CFPlatform.c中找到了这个

// For the use of CF and Foundation only
CF_EXPORT void *_CFGetTSD(uint32_t slot) {
    if (slot > CF_TSD_MAX_SLOTS) {
        _CFLogSimple(kCFLogLevelError, "Error: TSD slot %d out of range (get)", slot);
        HALT;
    }
    __CFTSDTable *table = __CFTSDGetTable();
    if (!table) {
        // Someone is getting TSD during thread destruction. The table is gone, so we can't get any data anymore.
        _CFLogSimple(kCFLogLevelWarning, "Warning: TSD slot %d retrieved but the thread data has already been torn down.", slot);
        return NULL;
    }
    uintptr_t *slots = (uintptr_t *)(table->data);
    return (void *)slots[slot];
}

答案已在此处讨论过https://devforums.apple.com/message/596383#596383

看起来UI修改尝试在不同的线程中完成。
