嗨,应用中有拖拽选项,需要实现将对象拖拽到位置之后,在同一位置设置对象,但是我下面的代码实现不了,不知道怎么办?是在IOS6版本中的,谢谢大家们的帮助。
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
CGPoint touchPoint = [[touches anyObject] locationInView:self.view];
if (touchPoint.x > self.img1.frame.origin.x &&
touchPoint.x < self.img1.frame.origin.x + self.img1.frame.size.width &&
touchPoint.y > self.img1.frame.origin.y &&
touchPoint.y < self.img1.frame.origin.y + self.img1.frame.size.height )
{
self.img1.backgroundColor = self.img1.backgroundColor;
}
self.img1.frame = CGRectMake(self.homePosition.x, self.homePosition.y,
self.img1.frame.size.width,
self.img1.frame.size.height);
}
