拼图模快陌生的方法

//余数是行,除数是列
picFrame.origin.x = (i % 3) * (160 + 5);
picFrame.origin.y = (i / 3) * (160 + 5);
拼图模快陌生的方法及技巧:
imageView.tag = i;
CGRect f = [frameValue CGRectValue];
CGRectContainsPoint(f, tapPoint)
CGPoint currentPoint = [touch locationInView: self];
[_picImageViewArray exchangeObjectAtIndex: _blankIndex withObjectAtIndex: tapFrameIndex];
[_picFrameArray addObject: [NSValue valueWithCGRect: picFrame]];
