在升级Xcode9之前，代码是好的。
升级后，去在iPhone6模拟器中运行结果挂了：

好像是之前的：
Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason: ‘Only run on the main thread!’
但是觉得有点怪的是：
为何Xcode8之前编译出来的运行的都好好的，现在Xcode9编译运行却出错呢？
Xcode9 Terminating app due to uncaught exception NSInternalInconsistencyException reason Only run on the main thread
Xcode 9 Terminating app due to uncaught exception NSInternalInconsistencyException reason Only run on the main thread
Terminating app due to uncaught exception NSInternalInconsistencyException reason Only run on the main thread
ios – “Only run on the main thread” exception is simulator only – Stack Overflow
目前看起来貌似是：
这部分的代码：
dispatchBackground_async { //SingletonTaskVC().initData() if gCurUserItem.userInfo.jobType == .leader { SingletonTaskVC().curTaskVCType = .shopVisit }else if(gCurUserItem.userInfo.jobType == .MarketingManager){ SingletonTaskVC().curTaskVCType = .shopHeadInspection }else{ SingletonTaskVC().curTaskVCType = .workCalendar } //SingletonTaskVC().getTaskList() //SingletonTaskVC().getTasksCount() //let communityMeetingVC = CommunityMeetingViewController() // communityMeetingVC.getProcedure() let dealerListViewController = DealerListViewController() dealerListViewController.getDealerList() let addShopVisitVC = ManageShopVisitViewController() addShopVisitVC.getMissionItemList() SingletonNewsVC().getUnReadCount() getOrganization() getReportFilter() getProcedure() //SingletonRepoetVC().addWebView() } |
有问题。
然后找到了可能出错的地方，就好办了。
以此去注视掉不同的代码，看看到底问题出在哪里。
另外，无意间发现，好像Xcode9中对出个提示：
DealerListViewController.swift: runtime: UI API called from background thread: -[UIView init] must be used from main thread only
然后点击开Thread 6，可以看到具体错误的地方：
所以，去想办法改掉这个写法
【总结】
此处，最诡异的，不是此处的代码有问题导致app崩溃，
而是有问题的代码，iOS11之前，竟然是可以正常运行的，app也没有崩溃。
而升级到了iOS11后，问题暴露出来，导致app崩溃了。
至今，没有找到为何iOS11之前为何没有导致app崩溃。
感觉是：iOS11之前，对于UI代码运行在非UI线程这个事情，检查的不够严格？
而此处的错误，通过Xcode9的智能提示，直接定位错误位置，很快就可以优化修复代码：
改为：
LoginViewController.swift
// let dealerListViewController = DealerListViewController() // dealerListViewController.getDealerList() getDealerList() |
DealerListViewController.swift
class DealerListViewController: UIViewController,UITableViewDelegate,UITableViewDataSource { init(curType:DealerListVCType = .singleSelect,dealerCodeList:[String] = [String](),dealerListCompletionHandler:((_ curDealerList:[Dealer]) -> Void)? = nil){ if self.dealerListCompletionHandler != nil { if gInformationStorage.dealerList.count == 0{ getDealerList(completionHandler: realoadDealerItem) }else{ realoadDealerItem() } } } } func getDealerList(completionHandler:(() -> Void)? = nil){ gInformationStorage.dealerList = [Dealer]() getUrlRespJson_async( httpMethod: .get, url: ServerApi.getDealerListUrl(), parameters: nil, respJsonHandle: { (response) in if response.isSuccess { gLog.debug(response.successValue) if let dealerItemJsonArray = response.successValue.array { for itemJson in dealerItemJsonArray { let dealer = Dealer() parseDealerJsonToItem(itemJson, dealerItem: dealer) gInformationStorage.dealerList.append(dealer) } if let completeCallback = completionHandler { completeCallback() } } } else if response.isFailure { // self?.noticeInfo(response.failedMessage) } }) } |
就可以了。
