CATransform3d 一个 UIButton
我似乎无法在按钮上进行简单的 3D 转换，并且文档似乎没有帮助。我从基于视图的应用程序模板开始。我添加了 QuartzCore 框架并将其导入到 ViewController 标头中。在界面生成器中，我拖出两个圆形矩形按钮并将它们分别连接到button1和button2，并将它们连接到buttonPressed：方法。
快速运行注释掉的动画可以验证只有单击的按钮才会更改其标签。
动画恢复后，我收到错误 Incomplete type for argument 1 of 'setTransform:' on the "sender.transform = t;"线（现在固定线更改为 [sender.layer setTransform:t];）
我如何让它旋转 360 度。我认为问题在于开始和结束状态是相同的，所以它不知道在任何地方旋转。
这是 .h（由于格式原因，我在本文中省略了导入）
@interface animation2ViewController : UIViewController {
IBOutlet UIButton *button1;
IBOutlet UIButton *button2;
}
-(IBAction) buttonPressed:(UIButton *)sender;
@end
和 .m 文件
#import "animation2ViewController.h"
@implementation animation2ViewController
-(IBAction)buttonPressed:(UIButton *)sender {
[sender setTitle:@"new title" forState:UIControlStateNormal];
[UIView animateWithDuration:1.0
delay:0.0
options:UIViewAnimationCurveEaseInOut
animations:^{
CATransform3D t = CATransform3DIdentity;
t.m34 = -1 / 1000;
t = CATransform3DRotate(t, 360 * M_PI / 180, 0.0, 1.0, 0.0); //ultimately want 360 degrees but starting here first
[sender.layer setTransform:t];
}
completion:^(BOOL finished) {
}];
}
I can't seem to get a simple 3d transform to work on a button and the documentation doesn't seem to be helping. I started with a View-based application template. I add in the QuartzCore framework and import it in the ViewController header. In interface builder I drag out two Round Rect Buttons and wire them up to button1, and button2 respectively, and also wire them both to the buttonPressed: method.
A quick run with the animation commented out verifies that only the button that is clicked changes its label.
With the animation back in I get an error Incompatible type for argument 1 of 'setTransform:' on the "sender.transform = t;" line (This is now fixed line changed to [sender.layer setTransform:t];)
How do I get it to rotate 360 degrees. I think the problem is that the start and end states are the same so it doesn't know to rotate through anywhere.
Here is the .h, (i left out the imports for formatting reasons in this post)
@interface animation2ViewController : UIViewController {
IBOutlet UIButton *button1;
IBOutlet UIButton *button2;
}
-(IBAction) buttonPressed:(UIButton *)sender;
@end
And the .m file
#import "animation2ViewController.h"
@implementation animation2ViewController
-(IBAction)buttonPressed:(UIButton *)sender {
[sender setTitle:@"new title" forState:UIControlStateNormal];
[UIView animateWithDuration:1.0
delay:0.0
options:UIViewAnimationCurveEaseInOut
animations:^{
CATransform3D t = CATransform3DIdentity;
t.m34 = -1 / 1000;
t = CATransform3DRotate(t, 360 * M_PI / 180, 0.0, 1.0, 0.0); //ultimately want 360 degrees but starting here first
[sender.layer setTransform:t];
}
completion:^(BOOL finished) {
}];
}

M_PI 是 180° 旋转，因此这意味着您旋转 360° 90 次。
尝试
t = CATransform3DRotate(t, M_PI, 0.0, 1.0, 0.0);对于设置器错误，请尝试
[sender.layer setTransform:t];因为你可以只变换图层
最后你需要在最后提交动画，否则它不会动画
[UIView 提交动画];M_PI is a rotation of 180°, so that means you do 90 times a 360°.
try
t = CATransform3DRotate(t, M_PI, 0.0, 1.0, 0.0);and for the setter error try
[sender.layer setTransform:t];because you can just transform the layer
And for the end you need to commit the animation at the end, otherwise it won't animate
[UIView commitAnimations];试试这个：
1/3 完整旋转你可能已经弄清楚了，因为你发布的帖子是一年多前的，但对于任何有同样问题的人来说，请尝试这样做它应该有效。
Try this :
1/3 of a full rotationYou have probably figured it out by now seeing as you post was over a year ago but for anyone with the same question try it like that it should work.
