PRRadialMenuPopover 0.1.2

您需要将类似以下内容添加到 Podfile 中：

target 'MyApp' do
  pod 'PRRadialMenuPopover', '~> 0.1'
end

然后在终端或从 CocoaPods.app 中运行 pod install。

或者为了进行测试运行，运行以下命令：

pod try PRRadialMenuPopover

PRRadialMenu 是从集合视图中的某一点扩展出来的按钮菜单。长按后显示菜单。菜单根据按钮数量调整间距。更多更新即将推出。

使用方法

要运行示例项目，首先从仓库 Clone，然后在示例目录中运行 pod install。

创建一个按钮数组并将其传递给 PopOverMenu。菜单将根据数组中的按钮数量进行调整。您必须为按钮的高亮和正常状态设置一个图片。以下是一种制作圆形按钮的简单方法。

 CGRect frame = CGRectMake(0, 0, 44, 44);
 
 UIButton *buttonView = [[UIButton alloc]initWithFrame:frame];
 
 [buttonView setImage:[UIImage imageNamed:@"Image-3"] forState:UIControlStateNormal];
 [buttonView setImage:[UIImage imageNamed:@"Image-2"] forState:UIControlStateHighlighted];
 
 UIButton *buttonView2 = [[UIButton alloc]initWithFrame:frame];
 
 [buttonView2 setImage:[UIImage imageNamed:@"Image-3"] forState:UIControlStateNormal];
 [buttonView2 setImage:[UIImage imageNamed:@"Image-2"] forState:UIControlStateHighlighted];
 
 
 UIButton *buttonView3 = [[UIButton alloc]initWithFrame:frame];
 
 [buttonView3 setImage:[UIImage imageNamed:@"Image-3"] forState:UIControlStateNormal];
 [buttonView3 setImage:[UIImage imageNamed:@"Image-2"] forState:UIControlStateHighlighted];
 
 UIButton *buttonView4 = [[UIButton alloc]initWithFrame:frame];
 
 [buttonView4 setImage:[UIImage imageNamed:@"Image-1"] forState:UIControlStateNormal];
 [buttonView4 setImage:[UIImage imageNamed:@"Image"] forState:UIControlStateHighlighted];
 
 buttonView.layer.shadowColor = [UIColor colorWithWhite:0.0 alpha:1.0].CGColor;
 buttonView.layer.shadowOffset = CGSizeMake(0, 0);
 buttonView.layer.shadowRadius = 2.0;
 buttonView.layer.shadowOpacity = 0.4;
 
 buttonView2.layer.shadowColor = [UIColor colorWithWhite:0.0 alpha:1.0].CGColor;
 buttonView2.layer.shadowOffset = CGSizeMake(0, 0);
 buttonView2.layer.shadowRadius = 2.0;
 buttonView2.layer.shadowOpacity = 0.4;
 
 buttonView3.layer.shadowColor = [UIColor colorWithWhite:0.0 alpha:1.0].CGColor;
 buttonView3.layer.shadowOffset = CGSizeMake(0, 0);
 buttonView3.layer.shadowRadius = 2.0;
 buttonView3.layer.shadowOpacity = 0.4;
 
 buttonView4.layer.shadowColor = [UIColor colorWithWhite:0.0 alpha:1.0].CGColor;
 buttonView4.layer.shadowOffset = CGSizeMake(0, 0);
 buttonView4.layer.shadowRadius = 2.0;
 buttonView4.layer.shadowOpacity = 0.4;
NSArray *buttonArray = @[buttonView, buttonView2, buttonView3, buttonView4];

接下来创建 PRPopoverButtonMenu，指派代理，并添加手势识别器。

self.touchContextMenu = [[PRPopoverButtonMenu alloc] initWithFrame:self.collectionView.frame
     withButtons:buttons   //array of buttons  
     helpText:helpText     //array of text to be displayed above buttons
     controller:self       //CollectionViewController using the menu, needed to translate coords
     withOffset:offset     //offset betweeen navbar and top of view.  Used to detect if buttons will animate under nav bar
     labelSize:CGSizeMake(60, 20)  //size of labels above butons  
     withRadius:80       //radius from long press gesture to center of button
     angleScaler:2.1     //a scaler that adjusts the angle between the buttons
     initialThetaOffset:0]; //the initial offset of the arc where the buttons are placed.

 //set the delegate method
 self.touchContextMenu.delegate = self;
 
 //add the gesture reconizer to the collection view
 [self.collectionView addGestureRecognizer:self.touchContextMenu.longPressReconizer];

Add the two delegate methods to the collectionviewcontroller

Used this method to show the menu.  Make sure there is a valid cell on the point pushed.
shouldShowAtPoint:(CGPoint)point 

Used this method get the index of a pushed button. The Point returned is the point of the gesture.
didSelectButton:(NSInteger)index atPoint:(CGPoint)point

  //Use this method to gurantee the location of the push was over a valid cell.
 - (BOOL) buttonMenu:(PRPopoverButtonMenu*)buttonMenu shouldShowAtPoint:(CGPoint)point {
         return ( [self.collectionView cellForItemAtIndexPath:[self.collectionView indexPathForItemAtPoint:point]] != nil );
 }
 
 //This method is called when the button a button has been pushed.
 - (void) buttonAtIndex:(PRPopoverButtonMenu *)buttonManager didSelectButton:(NSInteger)index atPoint:(CGPoint)point {
     NSIndexPath *cellPath = [self.collectionView indexPathForItemAtPoint:point];
     UICollectionViewCell *cell = [self.collectionView cellForItemAtIndexPath:cellPath];
 
     if ( !cell ) {
         return;
     }
 
     if ( index == 0 ) {
         NSLog(@"Action 1");
     } else if ( index == 1 ) {
         NSLog(@"Action 2");
     }else if(index == 2){
         NSLog(@"Action 3");
     }else {
         NSLog(@"Delete");
         self.cellNumber--;
         [self.collectionView deleteItemsAtIndexPaths:@[cellPath]];
     }

 }
