Question

我正试图进行1.) The Class.forName() SPI logic where you can inject the expected business logic on the fly. 2.) The Spring DI with interfaces and implementations using auto wiring摇晃。我已经让Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click If TextBox1.Text = "" Then MsgBox("enter word to search for") TextBox1.Focus() Exit Sub End If WebBrowser1.Hide()保持按钮单击，但摇动动画无效。这就是我所拥有的：

UIAlertView

我尝试在alertView中添加- (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex == 1) { self.direction = 1; self.shakes = 0; [self shake:aUIView]; } } -(void)shake:(UIAlertView *)theOneYouWannaShake { [UIView animateWithDuration:0.03 animations:^ { theOneYouWannaShake.transform = CGAffineTransformMakeTranslation(5 * self.direction, 0); } completion:^(BOOL finished) { if(self.shakes >= 10) { theOneYouWannaShake.transform = CGAffineTransformIdentity; return; } self.shakes++; self.direction = self.direction * -1; [self shake:theOneYouWannaShake]; }]; }并获得输出。所以我的代码一定有问题，为什么NSLog没有动摇。

Answer 1

您可以在iOS中使用 UIKit Dynamics 制作动画效果。这是tutorial使用 UIKit Dynamics 进行UIAlertView摇动动画。有关更多信息，您可以参考这个快速的 tutorial 。

我创造了一种幻觉，让警报看起来像是在颤抖。如果您必须设置参数，直到警报视图（包括深色背景屏幕）应该抖动的程度。

由于您无法使用UIAlertView的帧进行更改，因此请转到CGTranformations。

UIAlertView *dialog = [[UIAlertView alloc] initWithTitle:@"Title"
                                                 message:@"Message:"
                                                delegate:self cancelButtonTitle:@"Cancel"
                                       otherButtonTitles:@"Done", nil];

[dialog setAlertViewStyle:UIAlertViewStylePlainTextInput];
[dialog show];


UIView *dillusionView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
[dillusionView setBackgroundColor:[UIColor blackColor]];
[self.view addSubview:dillusionView];


[UIView animateKeyframesWithDuration:1.0 delay:0.0 options:UIViewKeyframeAnimationOptionAutoreverse | UIViewKeyframeAnimationOptionRepeat animations:^{
    [UIView addKeyframeWithRelativeStartTime:0.0 relativeDuration:0.5 animations:^{
        dialog.window.transform = CGAffineTransformTranslate(dialog.transform, dialog.frame.origin.x - 10, dialog.frame.origin.y);
    }];
    [UIView addKeyframeWithRelativeStartTime:0.5 relativeDuration:0.5 animations:^{
        dialog.window.transform = CGAffineTransformTranslate(dialog.transform, dialog.frame.origin.x + 10, dialog.frame.origin.y);
    }];
} completion:nil];

我建议使用自定义创建的UIAlertView，也可以使用很少的开源库。
