    <p>I have two UIButtons and I want to click first in the Number1 <code>UIButton</code> and then in the Number 2 <code>UIButton</code>. After clicking the second <code>UIButton</code> I want the two <code>UIButton</code>'s to be rotated automatically. I use <code>CABasicAnimation</code> to rotate them. The two <code>UIButton</code>'s have the same <code>buttonClicked</code> action. The two buttons use different <code>CABasicAnimation</code> methods.</p> <p>I have created a new method in order to rotate it, but when I call it from the <code>button clicked</code> action (same for the two buttons) only the first one is rotated. In order to call the rotate method I use <code>[self rotateButtons];</code></p> <p>The problem is that If I insert a new <code>UIButton</code> and give an <code>IBAction</code> to the new button it's fine. But I don't want a new button in the layer.</p> <p>How I fix <code>rotateButtons</code> so that both buttons <strong>could be rotated simultaneously</strong>?</p> <p>Here is the code:</p> <pre><code>- (void)animationDidStop:(CAAnimation *)theAnimation finished:(BOOL)flag { if ([value isEqualToString:@"SecondImage"]) { UIImageView *myView2=(UIImageView *)[self.view viewWithTag:numberOfCurrentButton+100]; [myView2 setHidden:FALSE]; UIImageView *myView=(UIImageView *)[self.view viewWithTag:numberOfCurrentButton]; [myView setHidden:TRUE]; CALayer *layer2 = myView2.layer; layer2.anchorPoint = CGPointMake(0.5f, 0.5f); CABasicAnimation *animateImage2 = [CABasicAnimation animationWithKeyPath: @"transform"]; CATransform3D transform2 = CATransform3DIdentity; transform2.m34 = 1.0/-900.0; self.view.layer.transform = transform2; layer2.transform = CATransform3DMakeRotation(-M_PI/2, 0.0f, 1.0f, 0.0f); self.view.layer.transform = transform2; transform2 = CATransform3DRotate(transform2, -M_PI, 0.0f, 1.0f, 0.0f); animateImage2.repeatCount = 1.0; animateImage2.toValue = [NSValue valueWithCATransform3D: transform2]; animateImage2.duration = 0.5; animateImage2.fillMode = kCAFillModeForwards; animateImage2.removedOnCompletion = NO; [layer2 addAnimation: animateImage2 forKey: @"halfAnimatedImage"]; return; } } -(void) rotateView1 { UIImageView *firstImage=(UIImageView *)[self.view viewWithTag:numberOfCurrentButton]; CALayer *layer = firstImage.layer; layer.anchorPoint = CGPointMake(0.5f, 0.5f); CABasicAnimation *animateImage = [CABasicAnimation animationWithKeyPath: @"transform"]; CATransform3D transform = CATransform3DIdentity; transform.m34 = 1.0/-900.0; self.view.layer.transform = transform; layer.transform = CATransform3DMakeRotation(M_PI, 0.0f, 1.0f, 0.0f); [animateImage setDelegate:self ]; animateImage.repeatCount = 0.5; animateImage.toValue = [NSValue valueWithCATransform3D: transform]; animateImage.duration = 0.5; animateImage.fillMode = kCAFillModeForwards; animateImage.removedOnCompletion = NO; animateImage.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]; [animateImage setValue:@"SecondImage" forKey:@"halfAnimatedImage"]; [layer addAnimation: animateImage forKey: @"halfAnimatedImage"]; } -(void) rotateView2 { UIImageView *firstImage=(UIImageView *)[self.view viewWithTag:numberOfCurrentButton]; CALayer *layer = firstImage.layer; layer.anchorPoint = CGPointMake(0.5f, 0.5f); CABasicAnimation *animateImage = [CABasicAnimation animationWithKeyPath: @"transform"]; CATransform3D transform = CATransform3DIdentity; transform.m34 = 1.0/-900.0; self.view.layer.transform = transform; layer.transform = CATransform3DMakeRotation(M_PI, 0.0f, 1.0f, 0.0f); [animateImage setDelegate:self ]; animateImage.repeatCount = 0.5; animateImage.toValue = [NSValue valueWithCATransform3D: transform]; animateImage.duration = 0.5; animateImage.fillMode = kCAFillModeForwards; animateImage.removedOnCompletion = NO; animateImage.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]; [animateImage setValue:@"SecondImage" forKey:@"halfAnimatedImage"]; [layer addAnimation: animateImage forKey: @"halfAnimatedImage"]; } -(IBAction) buttonRefresh:(UIButton *)sender { numberOfCurrentButton=1; [self rotateView1]; numberOfCurrentButton=2; [self rotateView2]; } -(IBAction)buttonClicked:(UIButton *)sender { [self buttonRefresh:sender]; } </code></pre> <p>` </p>

    1. COYou might want to include some code in your question to show what you've tried so far, and maybe some images to graphically describe what you're attempting to do?

    2. CO@MichaelDautermann I upload the code for the program. The action buttonClicked is for the two UIButtons. I want, when click on the second UIButton, the buttonRefresh action be started and rotate the two buttons.

    3. COSince rotateView1 and rotateView2 are identical, it would be easier to create a new `-(void)rotateViewWithTag:(NSInteger)tag {` method....

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
