let filename = getDocumentsDirectory().appendingPathComponent(upload.fileName)
print("deleting")
let fileNameToDelete = upload.fileName
var filePath = ""
// Fine documents directory on device
let dirs : [String] = NSSearchPathForDirectoriesInDomains(FileManager.SearchPathDirectory.documentDirectory, FileManager.SearchPathDomainMask.allDomainsMask, true)
if dirs.count > 0 {
let dir = dirs[0] //documents directory
filePath = dir.appendingFormat("/" + fileNameToDelete)
print("Local path = \(filePath)")
} else {
print("Could not find local directory to store file")
return
}
print(filename)
print("deleting111111")
do {
let fileManager = FileManager.default
// Check if file exists
print("filePath")
print(filePath)
print("filePath")
if fileManager.fileExists(atPath: filePath) {
// Delete file
try fileManager.removeItem(atPath: filePath)
} else {
print("File does not exist")
}
}
catch let error as NSError {
print("An error took place: \(error)")
}}
这打印在下面。为什么删除不起作用?为什么上面的函数在文件中向我抛出它不存在

答案 0 :(得分:0)
如果您通过写入使用
生成的文件名来创建文件.right {
margin-right: 2%;
margin-left: auto;
float: right;
}
...然后绝对至关重要,当删除文件的时候,你以完全相同的方式生成文件名。那不是你在做什么。
实际上,在您展示的代码中,您确实生成了一个名为<div class="social">
的变量,其代码看起来很相似:
filename = getDocumentsDirectory().appendingPathComponent(nameOfImage+".PNG")
...但是你永远不会使用 filename
做任何事情!因此,你不断伪装自己。您创建let filename = getDocumentsDirectory().appendingPathComponent(upload.fileName)
,打印filename
,但不使用filename
作为删除路径。您使用以不同方式获得的其他变量filename
。
