iOS 获取 APP 的 Launch Image

CGSize viewSize = self.window.bounds.size;
NSString viewOrientation = @"Portrait";
//横屏请设置成 @"Landscape" NSString launchImage = nil;
NSArray imagesDict = [[[NSBundle mainBundle] infoDictionary] valueForKey:@"UILaunchImages"];
for (NSDictionary dict in imagesDict) {
CGSize imageSize = CGSizeFromString(dict[@"UILaunchImageSize"]); if (CGSizeEqualToSize(imageSize, viewSize) && [viewOrientation isEqualToString:dict[@"UILaunchImageOrientation"]]) { launchImage = dict[@"UILaunchImageName"]; } } UIImageView *launchView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:launchImage]]; launchView.frame = self.window.bounds; launchView.contentMode = UIViewContentModeScaleAspectFill; [self.window addSubview:launchView];
[UIView animateWithDuration:2.0f delay:0.0f options:UIViewAnimationOptionBeginFromCurrentState animations:^{
launchView.alpha = 0.0f;
launchView.layer.transform = CATransform3DScale(CATransform3DIdentity, 1.2, 1.2, 1); } completion:^(BOOL finished) {
[launchView removeFromSuperview];
}];
