Ios ZipArchive阻塞主线程
当使用ZipArchive解压包时,它似乎阻塞了主线程。zip文件中大约有283个文件。我把它放在背景线上,但它似乎没有帮助Ios ZipArchive阻塞主线程,ios,objective-c,zip,Ios,Objective C,Zip,当使用ZipArchive解压包时,它似乎阻塞了主线程。zip文件中大约有283个文件。我把它放在背景线上,但它似乎没有帮助 dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, (unsigned long) NULL), ^{ [self tryUnzipFile:fileName inContentPackage:contentPackage]; }); - (void)try

上面的代码在解压时将屏幕冻结约5秒。我以为把它放在背景线程上会有帮助,但事实并非如此。任何帮助都会很棒

如果这个上下文中的“自我”是你的VIEW /VIEW控制器,你应该考虑在同步块中使用另一个变量。
你可以在没有“@同步”的情况下测试它吗?这没什么帮助。它仍然冻结了UIC,实际上这似乎改善了很多。谢谢
