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

@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

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);}···
