Powerbi中如何实现带图标的按钮

Posted 2023-04-30

参考技术A 插入按钮。
在插入功能区上选择按钮，一个下拉菜单随即显示，可在其中的一系列选项中选择所需按钮，在报表画布上选择按钮时，设置按钮格式窗格提供众多途径助你根据自己的需求来自定义按钮。
PowerBI中的按钮有三种状态：默认状态（未悬停或选中时的显示方式）、悬停状态或选中状态（通常指被单击）。你可根据这三种状态单独修改设置按钮格式窗格中的许多卡片，从而灵活地自定义按钮。

iOS - 一个简单的带标题的图标的实现

代码不复杂，直接上代码：

ImageViewButton.h

//
//  ImageViewButton.h//
//  带有图片、底部标题或者顶部的按钮
//
//

#import <UIKit/UIKit.h>

NS_ASSUME_NONNULL_BEGIN

@interface ImageViewButton : UIView

/**
 * 带有图标标题的按钮
 *
 * @param frame 大小
 * @param image 图标
 * @param title 标题
 * @param topTitle 标题是否在顶部
 *
 */
- (instancetype)initWithFrame:(CGRect)frame image:(NSString *)image title:(NSString *)title topTitle:(BOOL)topTitle;

// 按钮点击回调
@property (copy, nonatomic) void (^iconClickCallback) (void);

@end

NS_ASSUME_NONNULL_END

ImageViewButton.m

//
//  ImageViewButton.m
//

#import "ImageViewButton.h"

@interface ImageViewButton ()

// 图标
@property (strong, nonatomic) UIButton *iconButton;
// 标题
@property (strong, nonatomic) UILabel *titleLabel;
// 标题是否在顶部
@property (assign, nonatomic) BOOL topTitle;

@end

@implementation ImageViewButton

- (instancetype)initWithFrame:(CGRect)frame image:(NSString *)image title:(NSString *)title topTitle:(BOOL)topTitle {
    if (self = [super initWithFrame:frame]) {
        self.topTitle = topTitle;
        self.translatesAutoresizingMaskIntoConstraints = NO;
        
        // 图标
        self.iconButton = [[UIButton alloc] initWithFrame:CGRectZero];
        
        self.iconButton.translatesAutoresizingMaskIntoConstraints = NO;
        [self.iconButton setImage:[UIImage imageNamed:image] forState:UIControlStateNormal];
        [self.iconButton addTarget:self action:@selector(iconButtonClick:) forControlEvents:UIControlEventTouchUpInside];
        
        [self addSubview:self.iconButton];
        
        // 标题

        self.titleLabel.translatesAutoresizingMaskIntoConstraints = NO;
        self.titleLabel.textAlignment = NSTextAlignmentCenter;
        self.titleLabel.textColor = [UIColor whiteColor];
        self.titleLabel.text = title;
        
        [self addSubview:self.titleLabel];
