Xcode16 iOS18 编译问题适配

news 来源：原创 2024/9/27 1:23:57

问题1：ADClient编译报错问题

报错信息

Undefined symbols for architecture arm64:"_OBJC_CLASS_$_ADClient", referenced from:in ViewController.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

原因

苹果对AdClicent API加了一个标识
ADCLIENT_DEPRECATED_IOS_90_145_OBSOLETED_180
表示：iOS7.1-iOS14.5可用，iOS18彻底废弃，会在iOS18系统上编译失败。

解决办法

使用AdService库的AAAttribution替代，注意iOS14.3才可以使用。

代码

if (@available(ios 14.3, *)) {NSError *error;NSString *token = [AAAttribution attributionTokenWithError:&error];if (token != nil) {...}
}

问题2：Xcode16（正式版）运行时，YYCache导致crash

报错信息

原因

在 iOS18 中，需要提前对 sqlite3_stmt 执行 sqlite3_finalize。

解决办法

代码

- (BOOL)_dbClose {if (!_db) return YES;int  result = 0;BOOL retry = NO;BOOL stmtFinalized = NO;if (@available(iOS 18, *)) {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);}} else {if (_dbStmtCache) CFRelease(_dbStmtCache);_dbStmtCache = NULL;}do {retry = NO;result = sqlite3_close(_db);if (result == SQLITE_BUSY || result == SQLITE_LOCKED) {if (!stmtFinalized) {stmtFinalized = YES;sqlite3_stmt *stmt;while ((stmt = sqlite3_next_stmt(_db, nil)) != 0) {sqlite3_finalize(stmt);retry = YES;}}} else if (result != SQLITE_OK) {if (_errorLogsEnabled) {NSLog(@"%s line:%d sqlite close failed (%d).", __FUNCTION__, __LINE__, result);}}} while (retry);_db = NULL;return YES;
}

问题3：Xcode16正式版，addSubView crash （maskView）

报错信息
