ios - 删除文件名中带有空格的文件 ios

我想删除文档目录的图像。该图像具有这种 2016-06-08 12:24:55.897image.jpg 类型的命名约定。

代码片段

-(void) removeImageAtPathNSString *) filePath{
NSError *error;
NSFileManager *fileManager = [NSFileManager defaultManager];
BOOL success = [fileManager removeItemAtPath:filePath error:&error];
if (success) {
    NSLog(@"Image Successfully Deleted");
}
else{
    NSLog(@"Could not delete file -:%@ ",[error localizedDescription]);
}
}

错误代码 NSCocoaErrorDomain 代码 = 4

我知道找不到文件时会出现错误。这是由于我使用的命名约定而发生的。 我不能改变约定。有什么办法仍然可以删除文件。

此代码直接删除文件名

 - (void)removeImageNSString *)filename
    {
      NSFileManager *fileManager = [NSFileManager defaultManager];
      NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

      NSString *filePath = [documentsPath stringByAppendingPathComponent:filename];
      NSError *error;
      BOOL success = [fileManager removeItemAtPath:filePath error:&error];
      if (success) {
          UIAlertView *removedSuccessFullyAlert = [[UIAlertView alloc] initWithTitle"Congratulations:" message"Successfully removed" delegate:self cancelButtonTitle"Close" otherButtonTitles:nil];
          [removedSuccessFullyAlert show];
      }
      else
      {
          NSLog(@"Could not delete file -:%@ ",[error localizedDescription]);
      }
    }

其他明智的使用此代码

NSError *error;
if ([[NSFileManager defaultManager] isDeletableFileAtPath:path]) {
    BOOL success = [[NSFileManager defaultManager] removeItemAtPath:path error:&error];
    if (!success) {
        NSLog(@"Error removing file at path: %@", error.localizedDescription);
    }
}

你能试试这个代码吗

NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
BOOL fileExists = [fileManager fileExistsAtPath:path];
NSLog(@"ath to file: %@", path);        
NSLog(@"File exists: %d", fileExists);
NSLog(@"Is deletable file at path: %d", [fileManager isDeletableFileAtPath:path]);
if (fileExists) 
{
    BOOL success = [fileManager removeItemAtPath:path error:&error];
    if (!success) NSLog(@"Error: %@", [error localizedDescription]);
}
