旋转UIButton [英] Rotating UIButton

问题描述

我一直在尝试使用以下方法旋转按钮:

I've been trying to rotate a button using the following method:

-(IBAction)rotate:(id)sender{
    CGPoint pencilCenter = pencil.center;
    [pencil setCenter:pencilCenter];
    CGFloat floater = 1.0;
    [UIView animateWithDuration:0.7 animations:^(void){
        [pencil setTransform:CGAffineTransformMakeRotation(floater)];
    }];
    [UIView animateWithDuration:0.7 animations:^(void){
        [pencil setTransform:CGAffineTransformMakeRotation(floater)];
    }];
}

这应该使按钮产生某种抖动"，然后应该恢复到其原始位置-但它所做的只是改变按钮的位置，仅将按钮移动到一侧并在另一侧运行按钮完全不响应的方法.

This is supposed to make the button do some kind of "shake", then it's supposed to be back in its original position- yet all it does is changing the button's location, moving it to only one side and on another run of the method the button doesn't react at all.

我的代码有什么问题?

谢谢！

我的问题是-如何制作一个按钮以进行一些摇动/摆动，例如编辑spingboard时的摆动应用程序模式.

EDIT 2: My que is- how do I make a button to do a little shake/wiggle ,e.g. the wiggle app mode when editing sptingboard.

使用此代码使我向左旋转，从左到右然后从右到左平滑动画，然后旋转到原始位置.现在，我希望它不只是旋转，而是通过动画(例如摆动)来做到这一点.

Using this code is giving me rotation to left, smooth animates from left to right then right to left, then rotates to original position. Now, I want this not to just rotate, but do this with an animation, like a wiggle.

[UIView animateWithDuration:0.25
                      delay:0.0
                    options:(UIViewAnimationOptionAllowUserInteraction | UIViewAnimationCurveLinear | UIViewAnimationOptionAutoreverse)
                 animations:^ {
                     pencil.transform = CGAffineTransformMakeRotation(DEGREES_TO_RADIANS(30));
                     pencil.transform = CGAffineTransformIdentity;
                 }
                 completion:^(BOOL finished){
                 }
 ];

谢谢！

推荐答案

导入"QuartzCore/QuartzCore.h"并尝试执行此操作，

Import "QuartzCore/QuartzCore.h" and try this,

CABasicAnimation *fullRotation;
fullRotation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
fullRotation.delegate = self;
fullRotation.fromValue = [NSNumber numberWithFloat:0];
fullRotation.toValue = [NSNumber numberWithFloat:((360*M_PI)/180)];
fullRotation.duration = 1.7;
fullRotation.repeatCount = 2;
[btnTemp.layer addAnimation:fullRotation forKey:@"360"];
