我正在跟踪我的应用中的崩溃情况。这个特殊的崩溃给了我错误“由于未捕获的异常'终止应用程序'NSInternalInconsistencyException',原因:'只在主线程上运行!'”。奇怪的是,我似乎无法使用我的设备或模拟器重新创建崩溃,但在我的分析中,它显示此崩溃发生了很多。
这是崩溃发生的代码:
indicator.startAnimation()
let audioData = NSData(contentsOfURL: EditSongViewController.url.urlComplete!)
let dataImage: NSData = UIImageJPEGRepresentation(songImage.image!, 1.0)!
let imageFile = PFFile(name: "photo.jpg", data: dataImage)
let audioFile = PFFile(name: "song.mp4", data: audioData)
audioFile.saveInBackground()
imageFile.saveInBackground()
let testObject = PFObject(className: "PrivateSongs")
testObject["songFile"] = audioFile
testObject["image"] = imageFile
testObject["username"] = PFUser.currentUser().username
testObject["user"] = PFUser.currentUser()
testObject["title"] = self.songTitleText.text
testObject["songInfo"] = self.songInfoText.text
if RecordViewController.fileURL.songLyrics != nil {
testObject["lyrics"] = RecordViewController.fileURL.songLyrics
}
if (isPrivate == true) {
testObject["isPrivate"] = true
} else {
testObject["isPrivate"] = false
}
testObject.saveInBackgroundWithBlock ({ (success, error) -> Void in
if (success) {
if self.chartsSwitch.on {
let chart = PFObject(className: "Songs")
chart["artistName"] = PFUser.currentUser().username
chart["songFile"] = audioFile
chart["title"] = self.songTitleText.text
chart["picture"] = imageFile
chart["user"] = PFUser.currentUser()
chart["likes"] = 0
if RecordViewController.fileURL.songLyrics != nil {
chart["lyrics"] = RecordViewController.fileURL.songLyrics
}
chart.saveInBackground()
}
PostViewControler.share.shareUrl = audioFile.url!
self.postButton.hidden = true
self.addPictureButton.hidden = true
self.indicator.stopAnimation(false, completion: nil)
self.navigationController!.pushViewController(self.storyboard!.instantiateViewControllerWithIdentifier("ShareViewController") , animated: true)
} else {
self.indicator.stopAnimation(false, completion: nil)
self.helper.showErrorAlert("Couldn't save your song please try again.")
}
})

错误消息为list.delegates.get(i).input
。原因是您在后台线程(Only run on the main thread!
)中更新UI。检查更新UI任务,例如隐藏按钮,停止动画,导航...,并将其移动到主线程。
testObject.saveInBackgroundWithBlock ({ (success, error) -> Void in
