我嘗試刪除該文件,但是當我用「indexPath.row」把它送給我總是0文件名稱...從表中刪除,並刪除文件
這是我的代碼:
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
if (editingStyle == UITableViewCellEditingStyleDelete) {
// Delete the row from the data source
NSError *error = nil;
NSFileManager *manager = [NSFileManager defaultManager];
NSString *stringToPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/examples/"];
NSString *stringToFile = [NSString stringWithFormat:@"%@/%@.extension", stringToPath, [self.examples objectAtIndex:indexPath.row]];
[manager removeItemAtPath:[NSHomeDirectory() stringByAppendingPathComponent:stringToFile] error:&error];
if(!error){
NSLog(@"no error");
}else{
NSLog(@"%@", error);
}
[self.manageObjectContext deleteObject:[self.examples objectAtIndex:indexPath.row]];
[self.manageObjectContext save:nil];
NSFetchRequest *fetchReq = [NSFetchRequest fetchRequestWithEntityName:@"Examples"];
self.examples = [self.manageObjectContext executeFetchRequest:fetchReq error:&error];
[tableView deleteRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
else if (editingStyle == UITableViewCellEditingStyleInsert) {
// Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view
}
}
這是錯誤,當我使用[self.examples objectAtIndex:indexPath.row]];

}).extension, NSUserStringVariant=(

)}
我用這個也但這也不能幫助我,我不能讓當前行的名稱(這個我刪除)... 的NSString * stringPath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES)objectAtIndex:0] stringByAppendingPathComponent:@「/ examples /」]; 我想刪除表中的名字等文件我表中的行是「刪除的示例名稱」當我滑動我的手指刪除行我也想刪除文件,但我不能得到名稱該行。文件名是行的名稱,我無法刪除該文件,因爲我無法在變量中獲取行的名稱... –
