I am newbie in objective-c.I have created a main window which I want to display in the right bottom of the current screen. I tried the following code

- (void)windowDidLoad
{
    NSPoint pos;

    pos.x = [[NSScreen mainScreen] visibleFrame].origin.x + [[NSScreen mainScreen] visibleFrame].size.width - [mywindow frame].size.width ;

    pos.y = [[NSScreen mainScreen] visibleFrame].origin.y + [[NSScreen mainScreen] visibleFrame].size.height - [mywindow frame].size.height;

    [mywindow setFrameTopLeftPoint:pos];

}

里面有什么问题?如何解决?

what is wrong with in it? How to resolve it?

推荐答案

使用

NSPoint pos; 
pos.x = [[NSScreen mainScreen] frame].size.width - [mywindow frame].size.width ;

pos.y = 0.0f;

[self.window setFrame:CGRectMake(pos.x, pos.y, [mywindow frame].size.width , [mywindow frame].size.height) display:YES];

因为 [[NSScreen mainScreen] frame].origin.x 将始终为 0.如果是 mac 屏幕，则从底部开始.

Because [[NSScreen mainScreen] frame].origin.x will always be 0. And in case of mac screen starts from bottom.
