UIGestures從兩手指向下滑動從頂部到底部

Question

非常多的手勢帶來一個單獨的菜單類與手勢是從屏幕的最高點到屏幕的最底部的兩個手指扯/拉。我需要的只是我調整其餘部分的代碼。謝謝！

你的問題還不夠清楚。

但是從我的理解，嘗試UIScreenEdgePanGestureRecorgnizer

-(void)viewDidLoad{ 
[super viewDidLoad]; 

UIScreenEdgePanGestureRecognizer *gesture = [[UIScreenEdgePanGestureRecognizer alloc]  initWithTarget:self action:@selector(handleGesture:)]; 

gesture.edges = UIRectEdgeTop; //you can change it to whatever edge you want 

[yourView addGestureRecognizer:gesture]; 

} 
-(void)handleGesture:(UIScreenEdgePanGestureRecognizer*)arg { 
//handle the gesture here 

}
