通过简化动画调整NSWindows的大小

Question

我正试图通过一个很好的缓动动画（EaseOut）来调整NSWindow（主要的）的大小。

我可以使用[NSWindow animator]，但我找不到添加缓动效果的方法。

您是否有想法或代码示例可以帮助我做到这一点？

Answer 1

选项1

float Y = 100;
float X = 200;

NSRect frame = [window frame];

frame.origin.y -= Y;
frame.size.height += Y;
frame.size.width += X;

[window setFrame:frame display:YES animate:YES];

选项2

float Y = 100;
float X = 200;

NSRect frame = [window frame];

frame.origin.y -= Y;
frame.size.height += Y;
frame.size.width += X;

NSDictionary *windowResize = @{
    NSViewAnimationTargetKey: window,
    NSViewAnimationEndFrameKey: [NSValue valueWithRect:frame]
};
NSDictionary *oldFadeOut = @{
    NSViewAnimationTargetKey: [NSNull null],
    NSViewAnimationEffectKey: NSViewAnimationFadeOutEffect
};
NSDictionary *newFadeIn = @{
    NSViewAnimationTargetKey: [NSNull null],
    NSViewAnimationEffectKey: NSViewAnimationFadeInEffect
};

NSArray *animations = @[windowResize, newFadeIn, oldFadeOut];
NSViewAnimation *animation = [[NSViewAnimation alloc] initWithViewAnimations: animations];

[animation setAnimationBlockingMode: NSAnimationBlocking];
[animation setAnimationCurve: NSAnimationEaseIn];
[animation setDuration: 2];     
[animation startAnimation]; 

Answer 2

[[NSWindow animator] setAlphaValue:0.0];

当您想再次显示窗口时，不要忘记将alpha值设置为1.0。
