NSImageView动画 [英] NSImageView animations

问题描述

我是Mac开发的新手，我们有没有类似的方法 imagev = [NSArray arrayWithObjects

I am new to Mac development, Do we have any methods like imagev = [NSArray arrayWithObjects

我需要一些类似iOS中我们想在Mac中做的事情

I need some thing like what we do in iOS want to do in mac,

imageVie.animationImages = [NSArray arrayWithObjects:
 [UIImage imageNamed:@"1.png"],[UIImage imageNamed:@"2.png"],
 [UIImage imageNamed:@"3.png"],[UIImage imageNamed:@"4.png"],
 [UIImage imageNamed:@"5.png"],[UIImage imageNamed:@"6.png"],
 [UIImage imageNamed:@"7.png"] ,nil];

在iPhone中，我该如何动画

In iPhone, How can i animate

致谢

推荐答案

我发现有人使用核心动画"方法来解决此问题对我来说足够近了.我做了些微修改.您需要@import QuartzCore;

I found someone using a Core Animation approach to this issue which was close enough for me. I modified it slightly. You need to @import QuartzCore;

- (void)awakeFromNib
{
    CALayer *layer = [CALayer layer];
    NSMutableArray *spinnerImages = [NSMutableArray arrayWithCapacity:30u];
    for (NSUInteger i = 0; i < 30; ++i)
    {
        NSString *imageName = [NSString stringWithFormat:@"spinner%@", @(i)];
        [spinnerImages addObject:[NSImage imageNamed:imageName]];
    }
    self.spinnerImages = spinnerImages;
    layer.frame = self.imageView.bounds;
    [self.imageView setLayer:layer]; // This view is just a container for the layer. Its frame can be managed by a xib.
    self.imageView.wantsLayer = YES;

    self.spinnerLayer = layer;
}

然后您可以像这样设置动画:

Then you can animate it like this:

- (void)stopAnimating
{
    if ([self.layer.animationKeys containsObject:kAnimationKey])
    {
        [self.layer removeAnimationForKey:kAnimationKey];
    }
}

- (void)startAnimating
{
    if ([self.layer.animationKeys containsObject:kAnimationKey])
    {
        return;
    }
    CAKeyframeAnimation *animation = [CAKeyframeAnimation animationWithKeyPath:kAnimationKey];
    [animation setCalculationMode:kCAAnimationDiscrete];
    [animation setDuration:1.0f];
    [animation setRepeatCount:HUGE_VALF];
    [animation setValues:self.spinnerImages];
    [self.spinnerLayer addAnimation:animation forKey:kAnimationKey];
}
