我创建了一个图像视图
for(int i=0; i<pcount; i++)
{
int x = rand() % 350;
int y = rand() % 350;
NSRect rect = NSMakeRect((x+10),(y+10), 200, 200);
//NSImageView *imageView
imageView1 = [[NSImageView alloc]initWithFrame:rect];
[imageView1 setTag:i];
// imageView = [[NSImageView alloc]initWithFrame:rect];
// [imageView1 rotateByAngle:rand() % 150];
[imageView1 setImageScaling:NSScaleToFit];
[imageView1 canBecomeKeyView];
NSImage *theImage = [[NSImage alloc]initWithContentsOfURL:(NSURL*)[patharray objectAtIndex:(i)]];
[imageView1 setImage:theImage];
[[imageView1 cell] setHighlighted:YES];
[[layoutCustom view] addSubview:imageView1 positioned:NSWindowMovedEventType relativeTo:nil];}
现在如何通过鼠标单击选择每个图像视图?提前致谢。
