  • 1.将array数组转换为string字符串 NSString *str = [array componentsJoinedByString:@"#"];...将string字符串拆分为array数组[有分割符]NSArray *array = [str componentsSeparatedByString:@"#"];/

    1.将array数组转换为string字符串

     NSString *str = [array componentsJoinedByString:@"#"];//#为分隔符

    输入:[str,kkk,jjj]
    输出:str#kkk#jjj

    2.将string字符串拆分为array数组[有分割符]

    NSArray *array = [str componentsSeparatedByString:@"#"];//#为分隔符

    输入: str#kkk#jjj
    输出: [str,kkk,jjj]

    继承EditText封装了一个多项功能的XEditText,具体非常实用的功能。具有如下特点:

    • 自带清除功能图标,点击清除输入内容
    • 输入时手机号时自动分割:138 0000 0000,提高用户体验,轻松实现;
    • 支持自定义分割符号和分割模板,如分割银行卡号:6000-0000-0000-0000-000;
    • 支持禁止Emoji表情符号输入;
    • drawableRight自定义,点击监听,配合PopupWindow等进行输入提示;
    • 支持仿iOS输入框风格

    Gradle

    dependencies{
        compile 'com.xw.repo:xedittext:1.0.6@aar'
    }

    效果演示

    demo3demo4
    demo5demo6


    Attributes

    attr format describe
    x_separator String 分隔符,默认是一个空格
    x_disableEmoji boolean 禁止Emoji输入, 默认可以输入
    x_customizeMarkerEnable boolean 是否自定义Marker
    x_showMarkerTime enum 显示Marker的时间:after_input(default), before_input, always
    x_iOSStyleEnable boolean 是否使用iOS风格

    Methods:

    方法名 描述
    setSeparator(String separator) 自定义分隔符,默认是一个空格
    setHasNoSeparator(boolean hasNoSeparator) 设置无分隔符,功能同普通EditText
    setPattern(int[] pattern) 自定义模板,默认常见手机号分割,即int[]{3,4,4}
    setClearDrawable(int resId) 自定义删除图标的图片资源
    setTextToSeparate(CharSequence c) 设置需要自动模板转换的内容
    getNonSeparatorText() 获得无分割符的内容
    setDisableEmoji(boolean disableEmoji) true, 设置禁止Emoji输入
    setOnTextChangeListener(OnTextChangeListener listener) 设置输入监听,功能与EditText的addOnTextChangeListener()完全一样

    SwiftUI iOS 超酷组件之支持文本分割炸裂徽标效果(教程含源码)

    看完本文您将掌握的技能

    若要分隔文本,组件需要两个重要的信息。一个是要爆炸的文本,另一个是定界符,用于定义应应用哪个规则进行爆炸。提供了五种不同的定界符:

    • .all
    • .character
    ("Hello World!", delimiter: .character)
    
    • .word (default if no specific delimiter is provided)
    ("Hello World!")
    
    • .sentence
    • custom(regex: String)
    ("Hello World!", delimiter: .custom(regex: "(l)"))
    
    • 分割修饰符
    ("Hello World!").segmentModifier(...)
    
    • ViewModifier基础使用
    func segmenModifier<M: ViewModifier>(_ modifier: M) -> some View 
    

    基础知识

    ViewModifier

    应用于视图的修改器或另一个视图修改器,生成原始值的不同版本。

    protocol ViewModifier
    

    参考代码

    struct PressActions: ViewModifier {
        var onPress: () -> Void
        var onRelease: () -> Void
        
        func body(content: Content) -> some View {
            content
                .simultaneousGesture(
                    DragGesture(minimumDistance: 0)
                        .onChanged({ _ in
                            onPress()
                        })
                        .onEnded({ _ in
                            onRelease()
                        })
                )
        }
    }
    
    
    extension View {
        func pressAction(onPress: @escaping (() -> Void), onRelease: @escaping (() -> Void)) -> some View {
            modifier(PressActions(onPress: {
                onPress()
            }, onRelease: {
                onRelease()
            }))
        }
    }

                .segmenModifier(CircularBackground())
        }
    }
    
    struct CircularBackground: ViewModifier {
        
        let colors: [Color] = [.red, .blue, .green, .orange, .purple, .pink, .yellow]
        
        func body(content: Content) -> some View {
            content
                .foregroundColor(.white)
                .padding()
                .background(colors.randomElement())
