iPhone view move animation
提问by will du
I want to move one view to right when I clicked a button. I wrote something but it's not working;
当我单击一个按钮时，我想将一个视图向右移动。我写了一些东西，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){
}
];

try this code;
试试这个代码；
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");
}];

Do it like this .
像这样做 。
leftFrame is the frame where you can start and right frame is where you want to move to
leftFrame 是您可以开始的帧，而 right 帧是您要移动到的帧
UIView* view = [self.view viewWithTag:100];
if (!view) {
NSLog(@"nil");
}
[vw setFrame:leftFrame];
[UIView animateWithDuration:0.3f
animations:^{
[vw setFrame:rightFrame];
}
completion:^(BOOL finished){
}
];
Happy Coding :)
快乐编码:)

You can also move your view with smooth animation like this
您还可以像这样使用流畅的动画移动视图
- (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];
}
and call it like this
并像这样称呼它
[self moveViewPosition:120.0f forView:yourView];
for more you can also modify it to pass your require duration on function call like this.
更多信息，您还可以修改它以在这样的函数调用中传递您的要求持续时间。
- (void)moveViewPosition:(CGFloat)xPosition forView:(UIView *)view withDuration:(float)duration;
there are other options like
还有其他选择，比如
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");
}];
