像一枚硬币一样旋转图像 [英] Spinning an image around like a coin

问题描述

我有一个图片。我想旋转它像一枚硬币旋转表面。我试过旋转变换，但它不像这样旋转。如何实现这样的动画？

I have one image. I want to spin it like a coin spin on surface. I tried rotation transform but it does not spin like that. How to achieve such an animation?

代码：

- (void)viewDidLoad {
[super viewDidLoad];
[self.view setUserInteractionEnabled:YES];
lbl_facebook.font=[UIFont fontWithName:GZFont size:12.0f];
txtPassword.font=[UIFont fontWithName:GZFont size:15.0f];
txtUsername.font=[UIFont fontWithName:GZFont size:15.0f];

CATransition* transition = [CATransition animation];
transition.startProgress = 0;
transition.endProgress = 1.0;
transition.type = @"flip";
transition.subtype = @"fromRight";
transition.duration = 0.3;
transition.repeatCount = 2;
[_Image.layer addAnimation:transition forKey:@"transition"];

}

nd：

#import "LoginViewController.h"

#import "RegistrationViewController.h"
#import "ForgetPasswordViewController.h"
#import "ForgetPasswordController.h"
#import "SearchServiceProviderViewController.h"
#import <QuartzCore/QuartzCore.h>

推荐答案

硬币的图象有不同的角度的象转动的图象。然后将所有这些图像添加到数组，并开始动画的图像与那个数组...它会给你更好的效果...简单的过程，如视频帧。

One good trick to spin like this is that take different images of coin with different angle like spinning image. And then add all those images to array and start animation of images with that array..it will give you much better effect...Simple process like video framing.
