用easing動畫調整NSWindows

Question

我想用一個很好的緩動動畫（EaseOut）來調整NSWindow（主要的一個）的大小。

我可以使用[NSWindow animator]但我沒有帶發現了一種方法來添加寬鬆政策的效果。

你有一個想法或代碼示例，它可以幫助我做到這一點？

Answer 1

選項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]; 

選項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: nil, 
    NSViewAnimationEffectKey: NSViewAnimationFadeOutEffect 
}; 
NSDictionary *newFadeIn = @{ 
    NSViewAnimationTargetKey: nil, 
    NSViewAnimationEffectKey: NSViewAnimationFadeInEffect 
}; 

NSArray *animations = @[arrayWithObjects: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]; 

不要忘了阿爾法值設置爲1.0，當你想再次顯示窗口。
