iphone - UIView拖拽(图片和文字)

Question

是否可以在 UIView 同时具有图像和文本的情况下在 iOS 屏幕上拖动它？例如小卡片。你能指出类似的(已解决的)主题吗？我还没有找到。

Answer 1

这就是基于 pepouze 的回答的简洁解决方案(经过测试，有效!)

- (void) touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event 
{
    UITouch *aTouch = [touches anyObject];
    CGPoint location = [aTouch locationInView:self];
    CGPoint previousLocation = [aTouch previousLocationInView:self];
    self.frame = CGRectOffset(self.frame, (location.x - previousLocation.x), (location.y - previousLocation.y));
}
