我正在做一个应用程序，我需要在一个视图中绘制线条，并且应该自动出现在另一个视图中。任何帮助，将不胜感激..
这个我试过了。。
- (void)viewDidLoad
{
[super viewDidLoad];
slv = [[SmoothLineView alloc] initWithFrame:CGRectMake(DrawingView.bounds.origin.x, DrawingView.bounds.origin.y + 42, DrawingView.bounds.size.width, DrawingView.bounds.size.height - 42)];
slv.delegate = self;
[DrawingView addSubview:slv];
}
-(IBAction)btnAnotherView:(UIButton *)sender
{
[zoomingTypingView setUserInteractionEnabled:YES];
if(sender.tag == 123)
{
[self.view setBackgroundColor:[UIColor colorWithWhite:0.500 alpha:1.000]];
[UIView animateWithDuration:0.5
delay:0.1
options:UIViewAnimationTransitionCurlUp
animations:^{
//animation code
zoomingTypingView.frame = CGRectMake(0, 549, 768, 451);
} completion:^(BOOL finished) {
}];
CGRect imageFrame = CGRectMake(50, 50, 220, 120);
ResizableView = [[SPUserResizableView alloc] initWithFrame:imageFrame];
CGRect gripFrame = CGRectMake(50,50, 220,120);
UIView *zoom = [[UIView alloc]initWithFrame:gripFrame];
UIScrollView *zoomscroll = [[UIScrollView alloc]initWithFrame:gripFrame];
[zoomscroll setZoomScale:32.0];
[zoomscroll setMaximumZoomScale:32.0];
[zoom addSubview:zoomscroll];
[ResizableView setContentView:zoom];
ResizableView.delegate = self;
[DrawingView addSubview:ResizableView];
sender.tag = 246;
}
else
{
[UIView animateWithDuration:0.5
delay:0.1
options:UIViewAnimationTransitionCurlUp
animations:^{
//animation code
zoomingTypingView.frame = CGRectMake(0, 999, 768, 451);
} completion:^(BOOL finished) {
[self.view setBackgroundColor:[UIColor whiteColor]];
}];
[ResizableView removeFromSuperview];
[DrawingView addSubview:slv1];
sender.tag = 123;
}
}
在上面的图像中，WhiteColored 视图是新视图，如果我绘制应该反映在两个视图中的 whiteColoredView。
