我嘗試使用下面的代碼它在哪裏來從.document的URL用於快框架表視圖錯誤致命錯誤:超出範圍的索引加載文件
準備URL路徑加載到我的tableview時空當它第一次創建
var fileURLs = [NSURL]()
然後
private func prepareFileURLS() {
let csvFile = (FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)).last! as URL
if FileManager.default.fileExists(atPath: csvFile.path) {
fileURLs.append(csvFile as NSURL)
print(fileURLs)
}
}
然後使用下面的代碼給標籤的名稱
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let objectIdentifier = "ObjectsTableViewCell"
guard let cell = tableView.dequeueReusableCell(withIdentifier: objectIdentifier, for: indexPath) as? ObjectsTableViewCell else {
fatalError("The dequeued cell is not an instance of ObjectsTableViewCell")
}
//quickview
// Fetches the appropriate object for the data source layout
let currentFileParts = extractAndBreakFilenameInComponents(fileURL: fileURLs[indexPath.row])
cell.nameLabel.text = currentFileParts.fileName
//cell.photoImageView.image = cur.photo
//quickview
cell.descriptionLabel.text = getFileTypeFromFileExtension(fileExtension: currentFileParts.fileExtension)
return cell
}
,並使用下面的方法來打破路徑轉換爲字符串它導致錯誤
private func extractAndBreakFilenameInComponents(fileURL: NSURL) -> (fileName: String, fileExtension: String) {
// Break the NSURL path into its components and create a new array with those components.
let fileURLParts = fileURL.path!.components(separatedBy: "/")
// Get the file name from the last position of the array above.
let fileName = fileURLParts.last
// Break the file name into its components based on the period symbol (".").
let filenameParts = fileName?.components(separatedBy: ".")
// Return a tuple.
return (filenameParts![0], filenameParts![1]) --> Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)
}
致命錯誤:超出範圍的索引 我做了什麼錯?
檢查您的節數。也許你正試圖設置比你的網址中存在的數據高的行數。 – Amit
@Amit是你提到的那個嗎? FUNC的tableView(_的tableView:UITableView的,numberOfRowsInSection段中:int) - >詮釋{ 回報fileURLs.count } – JameS
是的,這是方法...與放置斷點cellforRowAt_indexpath再次運行代碼。並檢查你的代碼崩潰的迭代。 – Amit
