iPhone視圖移動動畫

[英]iPhone view move animation

我想點擊一個按鈕時將一個視圖移動到右邊。 我寫了些東西,但它不起作用;

UIView* view = [self.view viewWithTag:100];
if (!view) {
    NSLog(@"nil");
}

[UIView animateWithDuration:0.3f 
                 animations:^{
                     [view setTransform:CGAffineTransformMakeTranslation(-100, 0)];

                 }
                 completion:^(BOOL finished){

                 }
 ];

試試這段代碼;

  UIView* view = [self.view viewWithTag:100];
  [UIView animateWithDuration:0.5
                              delay:0.1
                            options: UIViewAnimationCurveEaseOut
                         animations:^
         {                 
             CGRect frame = view.frame;
             frame.origin.y = 0;
             frame.origin.x = (-100);
             view.frame = frame;
         }
                         completion:^(BOOL finished)
         {
             NSLog(@"Completed");

         }];

像這樣做 。

leftFrame是您可以開始的框架,右框架是您要移動到的框架

UIView* view = [self.view viewWithTag:100];
if (!view) {
    NSLog(@"nil");
}
[vw setFrame:leftFrame];
[UIView animateWithDuration:0.3f 
                 animations:^{
                        [vw setFrame:rightFrame];
                 }
                 completion:^(BOOL finished){
                 }
 ];

快樂編碼:)

您還可以使用像這樣的平滑動畫移動視圖

- (void)moveViewPosition:(CGFloat)xPosition forView:(UIView *)view
{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.2];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
[view setFrame:CGRectMake(xPosition, view.frame.origin.y,view.frame.size.width, view.frame.size.height)];
[UIView commitAnimations];
}

並稱之為這樣

[self moveViewPosition:120.0f forView:yourView];

對於更多,您也可以修改它以在這樣的函數調用上傳遞您的需要持續時間。

- (void)moveViewPosition:(CGFloat)xPosition forView:(UIView *)view withDuration:(float)duration;

還有其他選擇

 UIView* view = [self.view viewWithTag:99999];
 [UIView animateWithDuration:0.9
                          delay:0.0
                        options: UIViewAnimationCurveEaseOut
                     animations:^
     {                 
         CGRect frame = view.frame;
         frame.origin.y = 68;
         frame.origin.x = 0;
         view.frame = frame;
     }
                     completion:^(BOOL finished)
     {
         NSLog(@"Completed");

     }];
