objective-c - cocoa :如何让图标一直靠右？

Question

这个窗口的状态栏。如何让图标一直靠右呢？调整窗口大小，它会自动向右移动。

-(void)composeInterface{
    NSView *themeFrame=[[self.window contentView] superview];
    NSRect themeFrameRect = [themeFrame frame];
    NSRect accessoryViewFrame =[self.statusBarBtn frame];
    NSRect newFrame = NSMakeRect(30,
                                 themeFrameRect.size.height - accessoryViewFrame.size.height,
                                 accessoryViewFrame.size.width,
                                 accessoryViewFrame.size.height);

    [self.statusBarBtn setFrame:newFrame];
//    [self.statusBarBtn setFrameOrigin:NSMakePoint(0, 0)];
//    [self.statusBarBtn setAutoresizingMask:323];

    [themeFrame addSubview:self.statusBarBtn];
}

如果您希望您的图标右对齐，您需要将其自动调整大小更改为右对齐。您需要在尺寸检查器中这样做:

或者只是使用-setAutoresizingMask，如下所示:

[self.statusBarBtn setAutoresizingMask:333]; //NOT 323

此外，您的 newFrame 的 x 位置设置为 30，因此图标将位于左侧。

更改此:

NSRect newFrame = NSMakeRect(30,
                             themeFrameRect.size.height - accessoryViewFrame.size.height,
                             accessoryViewFrame.size.width,
                             accessoryViewFrame.size.height);

为此:

NSRect newFrame = NSMakeRect(themeFrameRect.size.width - accessoryViewFrame.size.width,
                             themeFrameRect.size.height - accessoryViewFrame.size.height,
                             accessoryViewFrame.size.width,
                             accessoryViewFrame.size.height);
