Xcode16 编译运行YYCache iOS18 sqlite3_finalize 闪退问题解决方案

问题原因

升级Xcode 16 之后，真机运行APP，发现会有Crash，崩溃堆栈线上Crash 在 YYCache 之中。如下图所示

崩溃堆栈如下：

解决方案一

swift 复制代码

@implementation YYKVStorage

- (BOOL)_dbClose {
   ...
    // 原代码
    if (_dbStmtCache) CFRelease(_dbStmtCache);

    // 替换为
    if (_dbStmtCache) {              
        CFIndex size = CFDictionaryGetCount(_dbStmtCache);
        CFTypeRef *valuesRef = (CFTypeRef *)malloc(size * sizeof(CFTypeRef));
        CFDictionaryGetKeysAndValues(_dbStmtCache, NULL, (const void **)valuesRef);
        const sqlite3_stmt **stmts = (const sqlite3_stmt **)valuesRef;
        for (CFIndex i = 0; i < size; i ++) {
            sqlite3_stmt *stmt = stmts[i];
            sqlite3_finalize(stmt);
        }
        free(valuesRef);
        CFRelease(_dbStmtCache);
    }
    ...
}

解决方案二

swift 复制代码

static void _finalizeStatement(const void *key, const void *value, void *context) {
    sqlite3_finalize((sqlite3_stmt *)value);
}

- (BOOL)_dbClose {
    ···
    
   // 原代码
    if (_dbStmtCache) CFRelease(_dbStmtCache);
   // 替换为
    if (_dbStmtCache) {              
        CFDictionaryApplyFunction(_dbStmtCache, _finalizeStatement, NULL);
        CFRelease(_dbStmtCache);
    }
    
    ···
}
