objective-c - 如何从 cocoa 的 super View 中删除imageview？

Question

当我重新加载单元格的NSTableView ImageView 时被覆盖。如何从 cocoa 的 super View 中删除imageview？

我尝试过以下代码:

NSImageView *tabIconImageview1=[[NSImageView alloc]initWithFrame:NSMakeRect(45, 12, 40, 40)];

[tabIconImageview removeFromSuperviewWithoutNeedingDisplay];
[tabIconImageview removeFromSuperview];
if ([strFilenames hasSuffix:@"."])
{
    [tabIconImageview1 setImage:[NSImage imageNamed:@"fileicon"]];
    //tabIconImageview1.image=[NSImage imageNamed:@"fileicon"];
}
else if ([strFilenames hasSuffix:@".exe"])
{
    [tabIconImageview1 setImage:[NSImage imageNamed:@"exeicon"]];
}
else if ([strFilenames hasSuffix:@"png"])
{
    [tabIconImageview1 setImage:[NSImage imageNamed:@"imageicon"]];
}
else if ([strFilenames hasSuffix:@".zip"])
{
    [tabIconImageview1 setImage:[NSImage imageNamed:@"zipicon"]];
}
else //if ([strFilenames hasSuffix:@"."])
{
    [tabIconImageview1 setImage:[NSImage imageNamed:@"foldericon"]];
}

[cellView addSubview:tabIconImageview1];

看我的截图，图像是重叠的。我怎样才能在 cocoa 中阻止它？

如果这是一个 NSTableView，请尝试刷新“已编辑”单元格或整个表格以重绘
