仿支付宝网格移动

一直想做类似的效果，还是api懂得太少，参考大神的demo，做了简单的封装，基本还是大神的思想。贴上大神demo地址：GitHub - fuzheng0301/MoveButton: 仿支付宝首页按钮的点击、长按、删除、添加、移动位置功能 

button网格封装的核心代码：

//响应格子的长安手势事件

- (void)gridLongPress:(UILongPressGestureRecognizer *)longPressGesture

{

switch (longPressGesture.state) {

case UIGestureRecognizerStateBegan:

{

[self.delegate pressGestureStateBegan:longPressGesture withGridItem:self];

break;

}

case UIGestureRecognizerStateChanged:

{

//应用移动后的新坐标

CGPoint newPoint = [longPressGesture locationInView:longPressGesture.view];

[self.delegate pressGestureStateChangedWithPoint:newPoint grigItem:self];

break;

}

case UIGestureRecognizerStateEnded:

{

[self.delegate pressGestureStateEnded:self];

break;

}

default:

break;

}

}

//根据格子的坐标计算格子的索引位置

+ (NSInteger)indexOfPoint:(CGPoint)point

withButton:(UIButton *)btn

gridArray:(NSMutableArray *)gridListArray

{

for (NSInteger i = 0;i< gridListArray.count;i++)

{

UIButton *appButton = gridListArray[i];

if (appButton != btn)

{

if (CGRectContainsPoint(appButton.frame, point))

{

return i;

}

}

}

return -1;

}

只是研究的大神的思想，做了一层简单的封装，只需要用数组或者model初始化LX_GridView即可，重置下view的高度，实现两个代理方法即可，
