我已經創建了小型iPhone應用程序。我把UITableView和放在單元格內的一些UIView。我添加了將單元格中的視圖水平移動的功能。現在我想添加邏輯來垂直移動整個UITableView,如果我在我的UIView中垂直移動我的手指。這是我的代碼:如何垂直移動UITableView
-(void)moveView:(UIPanGestureRecognizer *)recognizer
{
if([recognizer state] == UIGestureRecognizerStateBegan)
{
CGPoint location = [recognizer locationInView:[self superview]];
prevPos = location;
startPosition = self.frame.origin.x;
}
else if([recognizer state] == UIGestureRecognizerStateChanged)
{
CGPoint location = [recognizer locationInView:[self superview]];
float delX = location.x - prevPos.x;
float delY = location.y - prevPos.y;
if(delX > 0 && delX * delX > delY * delY)
{
CGPoint np = CGPointMake(self.frame.origin.x+delX, self.frame.origin.y);
CGRect fr = self.frame;
fr.origin = np;
self.frame = fr;
prevPos = location;
}
else if(delX * delX < delY * delY)
{
}
}
else if([recognizer state] == UIGestureRecognizerStateEnded ||
[recognizer state] == UIGestureRecognizerStateFailed ||
[recognizer state] == UIGestureRecognizerStateCancelled)
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];
CGRect rect = self.frame;
rect.origin.x = startPosition;
self.frame = rect;
startPosition = 0;
[UIView commitAnimations];
}
}
我應該在這種情況下輸入什麼代碼:else if(delX * delX < delY * delY)
?
謝謝!
感謝您的回答!它可以工作,但不能作爲tableView的標準行爲。是否有可能將控制權交給UITableView? – Radislav
爲什麼你想自己滾動tableView?是不是tableView滾動本身?如果不是爲什麼? – Lefteris
我不知道怎麼用英文解釋。如果我像往常一樣滾動表視圖 - 它的工作原理。如果我正在用手指嘗試scrool table view,但是用手指放在table cell中的UIView上。此視圖具有手勢識別器,可防止標準表視圖滾動。如果手指垂直移動,我需要將控制權交給表視圖。 – Radislav
