iOS 实现简单的移动UIView代码实例

在iewDidLoadzh中创建UIView

请访问http://www.hopean.com

UIView *tmpView = [[UIView alloc] initWithFrame:CGRectMake(30.0, 30.0, 45.0, 45.0)];
    tmpView.backgroundColor = [UIColor brownColor];
    tmpView.tag = 100;
    [self.view addSubview:tmpView];
    
    [tmpView release];

实现简单的移动UIView

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    UITouch *touch = [touches anyObject];
    UIView *viewDemo = (UIView*)[self.view  viewWithTag:100];
    CGPoint point = [touch  locationInView:self.view];
    CGRect  frame = viewDemo.frame;
    frame.origin = point;
    viewDemo.frame = frame;
}
