无法配置dataSource和委托

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,我在GitHub中使用的一些pod都在Swift中).我收到了一些错误,现在我被困在这些错误上了.出于某种原因,我的floatingSctionButton(git here)的dataSource和delegate 现在不起作用.我尝试设置dataSource和delegate编程和故事板,但它没有工作.

错误:

在'LiquidFloatingActionButton*'类型的对象上找不到属性'dataSource'

在'LiquidFloatingActionButton*'类型的对象上找不到属性'委托'

我相信,如果我弄清楚dataSource并delegate发出问题,那么它将修复下面的颜色错误.

.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];
}

我最终使用这个项目是因为原来的GitHub没有得到修复,感谢所有的帮助,如果有人想出来,请让大家知道!

我认为问题是你的 Objective-C 代码不知道 \xe2\x80\x9e open var\xe2\x80\x9csdataSource和Swiftdelegate代码LiquidFloatingButton。
\n为了让它们为人所知，需要一个 Obj-c 头文件来将这些 Swift 信息公开给您的 Obj-C 代码。Apple 文档 \xe2\x80\x9e Swift and Objective-C in the Same Project \xe2\x80\x9c对此进行了详细描述，在您的情况下，特别是在 \xe2\x80\x9e导入外部框架\xe2\部分x80\x9c。它说：
\n您可以使用以下语法将框架导入到不同目标中的任何 Objective-C .m 文件中：

@import FrameworkName;\n
