ios - 无法配置数据源和委托(delegate)

Question

所以我将 Xcode 和 GitHub 项目代码升级到 swift 3.0(我的项目在 Obj C 中，我从 GitHub 使用的一些 pod 在 Swift 中)。我遇到了一堆错误，现在我被困在这些错误上了。出于某种原因，我的数据源和 floatingActionButton ( git here ) 的委托(delegate)现在不起作用。我尝试以编程方式和 Storyboard上设置 dataSource 和 delegate，但没有成功。

错误:

Property 'dataSource' not found on object of type 'LiquidFloatingActionButton *'

Property 'delegate' not found on object of type 'LiquidFloatingActionButton *'

我相信如果我弄清楚 dataSource 和 delegate 问题，那么它会修复下面的颜色错误。

截图:

.h:

#import <UIKit/UIKit.h>

#import "ProductContentViewController.h"

#import "LiquidFloatingActionButton-swift.h"

@interface SetScreenViewController : UIViewController



<UIPageViewControllerDataSource, LiquidFloatingActionButtonDelegate, LiquidFloatingActionButtonDataSource>

...

@end

.m:

        #import "LiquidFloatingActionButton-Swift.h"

LiquidFloatingActionButton *floatingActionButton;
NSMutableArray *liquidCells;
bool *closeFloatingButtons;


NSString *videoToWatchURL;


- (void)addLiquidButton{

    //Grabs the coordinates bottom right of the screen    
    float X_Co = self.view.frame.size.width - 50;
    float Y_Co = self.view.frame.size.height - 50;

    //i subtract 10 so the button will be placed a little bit out
    X_Co = X_Co - 10;
    Y_Co = Y_Co - 10;


    //I create each cell and set the image for each button
    liquidCells = [[NSMutableArray alloc] init];
    [liquidCells addObject:[[LiquidFloatingCell alloc]initWithIcon:[UIImage imageNamed:@".png"]]];
    [liquidCells addObject:[[LiquidFloatingCell alloc]initWithIcon:[UIImage imageNamed:@".png"]]];
    [liquidCells addObject:[[LiquidFloatingCell alloc]initWithIcon:[UIImage imageNamed:@".png"]]];
    [liquidCells addObject:[[LiquidFloatingCell alloc]initWithIcon:[UIImage imageNamed:@".png"]]];
    [liquidCells addObject:[[LiquidFloatingCell alloc]initWithIcon:[UIImage imageNamed:@".png"]]];
    [liquidCells addObject:[[LiquidFloatingCell alloc]initWithIcon:[UIImage imageNamed:@".png"]]];



    //Sets the floating button at the loaction provided
    floatingActionButton = [[LiquidFloatingActionButton alloc] initWithFrame:CGRectMake(X_Co, Y_Co, 50, 50)];
    floatingActionButton.dataSource = self;//Error here
    floatingActionButton.delegate = self;//and here.

    //I set the color of the floating button
    floatingActionButton.color = [self colorWithHexString:@"01b8eb"];




    //Enables the user interaction fuction to true so itll open or close
    floatingActionButton.userInteractionEnabled = YES;

    //Adds the flaoting button to the view
    [self.view addSubview:floatingActionButton];
}

-(NSInteger)numberOfCells:(LiquidFloatingActionButton     *)liquidFloatingActionButton{
    return liquidCells.count;
}

-(LiquidFloatingCell *)cellForIndex:(NSInteger)index{
    return [liquidCells objectAtIndex:index];
}

UPDATE BELOW

我最终使用了 this项目，因为原始的 GitHub 没有被修复，感谢所有的帮助，如果有人解决了这个问题，请让这里的每个人都知道!

如果 swift @protocols 不是用 @objc 定义的，那么你不能在 objective-c 中访问它们，

例如

@objc public protocol xxxxxxxxxxxDelegate {
   func functionOne()
   func functionSecond()
}
