The HTML importer should not be called from a background thread (that is, the options dictionary includesNSDocumentTypeDocumentAttribute with a value of NSHTMLTextDocumentType). It will try to synchronize with the main thread, fail, and time out. Cal

今天花费了一天的时间来解决这个bug. 这种在程序运行期间出现的问题比较棘手,如果再没有规律的话就更难解决. 还好这个bug是由规律的,也就是说在程序执行半个小时左右后就会因为此异常而导致程序退出:那么在网上找了下原因,无非是说一下几点: 1.把业务放在子线程中去完成,然后通过handler来更新界面 2.通过runOnUiThread的方法来实现 再补充一点就是:优化代码,将不需要重复执行的代码执行一次就ok了,特别是需要绘制UI的代码更不能随便放在重复执行的地方 一.bug现场还原 我的程序

reloadData should be called in main thread, so if you call it in work thread, you should call it as follows: dispatch_async(dispatch_get_main_queue(), ^{ [_tableVC.tableView reloadData]; }); otherwise UI refresh will be delayed, but not realtime.

Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. 我的出现这个原因是,jquery的async: false,导致 async:true,(默认),异步方式,$.Ajax执行后,会继续执行ajax后面的脚本,直到服务器端返回数据后,触发$.Ajax里的success方法,这时候执行的是两个线程. a

Xcode打印栏出现如下警告: Main Thread Checker: UI API called on a background thread 这个是什么错误呢? 其实这并不一定是错误,也可以理解为一种警告,说他不是错误,是因为它不一定会影响你的代码功能,可能对你的实现功能毫无影响. 那么它的含义是这样: 这是Xcode 9的新特性:主线程检测器(Main Thread Checker). 出现的时候意味着:本来需要在主线程执行的代码 被你放在了子线程里边执行. 那么我们解决的话,只需要检查

问题描述: 部分手机频繁闪退的问题.比如:vivo y55a,在升级.交任务.穿戴装备等都有概率闪退... 表现: 卡几帧就马上闪退. 在学习技能.穿戴装备.升级等概率出现,新角色第3个任务“拦截少年”完成后指引穿戴武器后大概率闪退,这时同时还预加载2个剧情资源,处理较多事情. 闪退日志:Skipped 62 frames! The application may be doing too much work on its main thread,主线程做了太多事 解决历程: 最开始以为单帧处理

如果需要在异步任务(Async Task)中更新UI,若直接设置UI,会导致程序崩溃. 例如,在异步block中去更改UI: NSOperationQueue *queue=[[NSOperationQueue alloc] init]; [queue addOperationWithBlock:^{ @autoreleasepool { // the other codes ... _textView.text = [_textView.text stringByAppendingString
