Question

为什么我不能做任何CABasicAnimation或Keyframe动画的东西？

Tha*_*nks 2 iphone cocoa-touch core-animation uikit cabasicanimation

出于某种原因,Xcode告诉我,只要我使用像kCAFillModeForwards这样的东西就找不到符号.必须有一个图书馆或班级,我必须包括......但是哪一个？正常的核心动画的东西工作得很好[myView beginAnimations ...].让更复杂的动画制作工作的诀窍是什么？

我已经包含在.h文件中:

#import <UIKit/UIKit.h>
#import <QuartzCore/QuartzCore.h>

@interface TestClass : UIView {

}
// ...

我运行这段代码:

- (void)testAnimation {
    CABasicAnimation *fadeInAnimation = [CABasicAnimation animationWithKeyPath:@"opacity"];
    [fadeInAnimation setToValue:[NSNumber numberWithFloat:1.0]];
    fadeInAnimation.fillMode = kCAFillModeForwards;
    fadeInAnimation.removedOnCompletion = NO;
    // other stuff deleted to limit error possibilities...should at least compile
}

这种情况发生在我构建时(确实清理了很多次),2个错误:

它说未定义的符号:

我必须包含一些框架吗？

我已经包括:

CoreGraphics.framework Foundation.framework UIKit.framework

当我删除所有代码,但导入QuartzCore/QuartzCore.h,然后我没有得到任何错误.所以我打赌导入工作,但不确定.

解决了

我错过了包含QuartzCore框架!!
