小编ios*_*dev的帖子

在我的应用程序中,我使用了移动子View.If它达到y = 150,我想在跳跃效果中制作一个按钮,我试过这个链接为UIImageView的外观添加反弹效果它在水平方向工作,我想要一个垂直方向,这是我的代码,

-(void)godown 
 {
if (movingview.center.y < 150) movingview.center = CGPointMake(movingview.center.x, movingview.center.y +5);
if(movingview.center.y ==150)
{
  [UIView beginAnimations:@"bounce" context:nil];
  [UIView setAnimationRepeatCount:3];
  [UIView setAnimationRepeatAutoreverses:YES];  
  CGAffineTransform transform = CGAffineTransformMakeScale(1.3,1.3);
  bt1.transform = transform;
  bt2.transform=transform;
 [UIView commitAnimations];  
}
}

请帮我换成跳跃效果(垂直)？

如何增加UISegmentedControl中栏之间的空间？而不是创建一个单独的按钮.我想分割段控制条.

因为当我单击UITextField时,日期选择器与键盘一起显示,我想隐藏dob-text字段上的键盘操作？这里是我的代码

- (void)removeViews:(id)object 
    {
    [[self.view viewWithTag:9] removeFromSuperview];
    [[self.view viewWithTag:10] removeFromSuperview];
    [[self.view viewWithTag:11] removeFromSuperview];
    }

    - (void)dismissDatePicker:(id)sender 
    {
    CGRect toolbarTargetFrame = CGRectMake(0, self.view.bounds.size.height, 320, 44);
    CGRect datePickerTargetFrame = CGRectMake(0, self.view.bounds.size.height+44, 320, 216);
    [UIView beginAnimations:@"MoveOut" context:nil];
    [self.view viewWithTag:9].alpha = 0;
    [self.view viewWithTag:10].frame = datePickerTargetFrame;
    [self.view viewWithTag:11].frame = toolbarTargetFrame;
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDidStopSelector:@selector(removeViews:)];
    [UIView commitAnimations];
    }

    - (IBAction)but 
    {
    //[eventText resignFirstResponder];
    [dob resignFirstResponder];


    if ([self.view viewWithTag:9]) 
    {
        return;
    }
    CGRect toolbarTargetFrame = CGRectMake(0, self.view.bounds.size.height-216-44, 320, 44);
    CGRect datePickerTargetFrame = CGRectMake(0, self.view.bounds.size.height-216, 320, 216); …
