Usage

• Download the zip and drag KMReceiverCell folder into your project.
• Define shouldReloadCellBlock when using the cell, use code below:

	receiverCell.shouldReloadCellBlock = { [weak self] in
	    guard let ss = self else { return }
	    
	    let contentOffset = ss.tableView.contentOffset
	    print("before", contentOffset)
	    
	    UIView.setAnimationsEnabled(false)
	    ss.tableView.beginUpdates()
	    ss.tableView.endUpdates()
	    
	    if ss.receiverCell.isInputing {
	        ss.tableView.contentOffset = contentOffset
	    } else {
	        ss.tableView.setContentOffset(CGPoint(x: 0, y: -64), animated: false)
	    }
	    UIView.setAnimationsEnabled(true)
	    
	    // Uncomment these lines to set tableview's offset when begin editing.
	    /*
	     var new: CGPoint?
	    if ss.receiverCell.isInputing {
	        let contentHeight = ss.receiverCell.pillar.constant
	        let freeHeight = UIScreen.main.bounds.size.width - ss.keyboardRect.size.height - 64
	        
	        if contentHeight > freeHeight {
	            let offset =  contentHeight - freeHeight - 64
	            new = CGPoint(x: 0, y: offset)
	        }
	    }
	    if let new = new {
	        print("new", new)
	        DispatchQueue.main.asyncAfter(deadline: .now() + 0.15, execute: {
	            ss.tableView.setContentOffset(new, animated: true)
	        })
	    }
	    */
	}

• ReceiverCell provides several callbacks or handlers for managing actions.

	// MARK: - Callbacks & delegates
	public var shouldReloadCellBlock: (() -> Void)?
	public var shouldReplaceNameHandler: ((String) -> ReceiverCellModel?)?
	public var errorhandler: ((NSError) -> Void)?
	public var typeAddHandler: ((ReceiverCellModel) -> Void)?
	public var replaceAddHandler: ((ReceiverCellModel) -> Void)?
	public var deleteHandler: ((ReceiverCellModel) -> Void)?
	public var clickAddButton: (() -> Void)?
	public var doubleClickHandler: ((Int, ReceiverCellModel) -> Void)?

• All the receiver names or keywords are saved and delivered through class ReceiverCellModel.

• You can customize the text field in the cell, but unfortunately I haven't provide methods in the cell. You must change the source code in class ReceiverCell. ReceiverCellTextField Provide some delegates for changing appearance of different states:

    var borderColorForState: ((ReceiverTextFieldState) -> UIColor?)?
    var backgroundColorForState: ((ReceiverTextFieldState) -> UIColor?)?
    var textColorForState: ((ReceiverTextFieldState) -> UIColor?)?
