我們經(jīng)常會(huì)有多行多列按鈕的頁(yè)面, 這個(gè)時(shí)候我們通常會(huì)選擇循環(huán)創(chuàng)建按鈕, 然后進(jìn)行按鈕單選或者多選的操作!
在瀏陽(yáng)等地區(qū),都構(gòu)建了全面的區(qū)域性戰(zhàn)略布局,加強(qiáng)發(fā)展的系統(tǒng)性、市場(chǎng)前瞻性、產(chǎn)品創(chuàng)新能力,以專注、極致的服務(wù)理念,為客戶提供網(wǎng)站設(shè)計(jì)制作、成都做網(wǎng)站 網(wǎng)站設(shè)計(jì)制作按需定制開(kāi)發(fā),公司網(wǎng)站建設(shè),企業(yè)網(wǎng)站建設(shè),高端網(wǎng)站設(shè)計(jì),成都營(yíng)銷網(wǎng)站建設(shè),外貿(mào)網(wǎng)站建設(shè),瀏陽(yáng)網(wǎng)站建設(shè)費(fèi)用合理。
一. 單選邏輯處理
1. 創(chuàng)建按鈕控件數(shù)組及標(biāo)簽數(shù)組, 并升級(jí)當(dāng)前選中按鈕為屬性,方便使用
#define ZLUnselectedColor [UIColor colorWithRed:(241)/255.0 green:(242)/255.0 blue:(243)/255.0 alpha:1.0] #define ZLSelectedColor [UIColor colorWithRed:(108)/255.0 green:(187)/255.0 blue:(82)/255.0 alpha:1.0] @interface ZLRadioViewController () // 標(biāo)簽數(shù)組(按鈕文字) @property (nonatomic, strong) NSArray *markArray; // 按鈕數(shù)組 @property (nonatomic, strong) NSMutableArray *btnArray; // 選中按鈕 @property (nonatomic, strong) UIButton *selectedBtn; @end
#pragma mark - 懶加載 - (NSArray *)markArray { if (!_markArray) { NSArray *array = [NSArray array]; array = @[@"14", @"15", @"16", @"17", @"18"]; _markArray = array; } return _markArray; } - (NSMutableArray *)btnArray { if (!_btnArray) { NSMutableArray *array = [NSMutableArray array]; _btnArray = array; } return _btnArray; }
2. 創(chuàng)建單選視圖, 循環(huán)創(chuàng)建按鈕, 并回顯上次選中值
- (void)setupRadioBtnView { CGFloat UI_View_Width = [UIScreen mainScreen].bounds.size.width; CGFloat marginX = 15; CGFloat top = 100; CGFloat btnH = 30; CGFloat width = (250 - marginX * 4) / 3; // 按鈕背景 UIView *btnsBgView = [[UIView alloc] initWithFrame:CGRectMake((UI_View_Width - 250) * 0.5, 50, 250, 300)]; btnsBgView.backgroundColor = [UIColor whiteColor]; [self.view addSubview:btnsBgView]; // 循環(huán)創(chuàng)建按鈕 NSInteger maxCol = 3; for (NSInteger i = 0; i < 5; i++) { UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom]; btn.backgroundColor = ZLUnselectedColor; btn.layer.cornerRadius = 3.0; // 按鈕的邊框弧度 btn.clipsToBounds = YES; btn.titleLabel.font = [UIFont boldSystemFontOfSize:12]; [btn setTitleColor:[UIColor colorWithRed:(102)/255.0 green:(102)/255.0 blue:(102)/255.0 alpha:1.0] forState:UIControlStateNormal]; [btn setTitleColor:[UIColor whiteColor] forState:UIControlStateSelected]; [btn addTarget:self action:@selector(chooseMark:) forControlEvents:UIControlEventTouchUpInside]; NSInteger col = i % maxCol; //列 btn.x = marginX + col * (width + marginX); NSInteger row = i / maxCol; //行 btn.y = top + row * (btnH + marginX); btn.width = width; btn.height = btnH; [btn setTitle:self.markArray[i] forState:UIControlStateNormal]; [btnsBgView addSubview:btn]; btn.tag = i; [self.btnArray addObject:btn]; } // 創(chuàng)建完btn后再判斷是否能選擇(之前是已經(jīng)選取過(guò)的) // 假數(shù)據(jù):之前已經(jīng)上傳16時(shí),則回顯16 for (UIButton *btn in btnsBgView.subviews) { if ([@"16" isEqualToString:btn.titleLabel.text]) { btn.selected = YES; btn.backgroundColor = ZLSelectedColor; break; } } }
3. 數(shù)字按鈕單選處理, 根據(jù)tag值去判斷是否是當(dāng)前選中按鈕
- (void)chooseMark:(UIButton *)sender { NSLog(@"點(diǎn)擊了%@", sender.titleLabel.text); self.selectedBtn = sender; sender.selected = !sender.selected; for (NSInteger j = 0; j < [self.btnArray count]; j++) { UIButton *btn = self.btnArray[j] ; if (sender.tag == j) { btn.selected = sender.selected; } else { btn.selected = NO; } btn.backgroundColor = ZLUnselectedColor; } UIButton *btn = self.btnArray[sender.tag]; if (btn.selected) { btn.backgroundColor = ZLSelectedColor; } else { btn.backgroundColor = ZLUnselectedColor; } }
二. 多選邏輯處理
1. 創(chuàng)建按鈕控件數(shù)組和標(biāo)簽字典, 及選中標(biāo)簽數(shù)組(數(shù)字)和選中標(biāo)簽數(shù)組(文字字符串), 為了展示及上傳按鈕數(shù)據(jù)使用
#define ZLUnselectedColor [UIColor colorWithRed:(241)/255.0 green:(242)/255.0 blue:(243)/255.0 alpha:1.0] #define ZLSelectedColor [UIColor colorWithRed:(128)/255.0 green:(177)/255.0 blue:(34)/255.0 alpha:1.0] @interface ZLMultiselectController () // 標(biāo)簽數(shù)組 @property (nonatomic, strong) NSArray *markArray; // 標(biāo)簽字典 @property (nonatomic, strong) NSDictionary *markDict; // 選中標(biāo)簽數(shù)組(數(shù)字) @property (nonatomic, strong) NSMutableArray *selectedMarkArray; // 選中標(biāo)簽數(shù)組(文字字符串) @property (nonatomic, strong) NSMutableArray *selectedMarkStrArray; @end
#pragma mark - 懶加載 - (NSArray *)markArray { if (!_markArray) { NSArray *array = [NSArray array]; array = @[@"導(dǎo)購(gòu)", @"客服", @"家教", @"禮儀", @"主持"]; _markArray = array; } return _markArray; } // 上傳通過(guò)文字key取數(shù)字value發(fā)送數(shù)字 - (NSDictionary *)markDict { if (!_markDict) { NSDictionary *dict = [NSDictionary dictionary]; dict = @{ @"導(dǎo)購(gòu)" : @"3" , @"客服" : @"7", @"家教" : @"9", @"禮儀" : @"10", @"主持" : @"11", }; _markDict = dict; } return _markDict; } - (NSMutableArray *)selectedMarkArray { if (!_selectedMarkArray) { _selectedMarkArray = [NSMutableArray array]; } return _selectedMarkArray; } - (NSMutableArray *)selectedMarkStrArray { if (!_selectedMarkStrArray) { _selectedMarkStrArray = [NSMutableArray array]; } return _selectedMarkStrArray; }
2.循環(huán)創(chuàng)建按鈕視圖, 循環(huán)創(chuàng)建按鈕
- (void)setupMultiselectView { CGFloat UI_View_Width = [UIScreen mainScreen].bounds.size.width; CGFloat marginX = 15; CGFloat top = 19; CGFloat btnH = 35; CGFloat marginH = 40; CGFloat height = 130; CGFloat width = (UI_View_Width - marginX * 4) / 3; // 按鈕背景 UIView *btnsBgView = [[UIView alloc] initWithFrame:CGRectMake(0, 100, UI_View_Width, height)]; btnsBgView.backgroundColor = [UIColor whiteColor]; [self.view addSubview:btnsBgView]; // 循環(huán)創(chuàng)建按鈕 NSInteger maxCol = 3; for (NSInteger i = 0; i < 5; i++) { UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom]; btn.backgroundColor = ZLUnselectedColor; btn.layer.cornerRadius = 3.0; // 按鈕的邊框弧度 btn.clipsToBounds = YES; btn.titleLabel.font = [UIFont boldSystemFontOfSize:14]; [btn setTitleColor:[UIColor colorWithRed:(102)/255.0 green:(102)/255.0 blue:(102)/255.0 alpha:1.0] forState:UIControlStateNormal]; [btn setTitleColor:[UIColor whiteColor] forState:UIControlStateSelected]; [btn addTarget:self action:@selector(chooseMark:) forControlEvents:UIControlEventTouchUpInside]; NSInteger col = i % maxCol; //列 btn.x = marginX + col * (width + marginX); NSInteger row = i / maxCol; //行 btn.y = top + row * (btnH + marginX); btn.width = width; btn.height = btnH; [btn setTitle:self.markArray[i] forState:UIControlStateNormal]; [btnsBgView addSubview:btn]; } // 確定按鈕 UIButton *surebtn = [UIButton buttonWithType:UIButtonTypeCustom]; [surebtn setTitle:@"確定" forState:UIControlStateNormal]; surebtn.frame = CGRectMake(marginX * 2, CGRectGetMaxY(btnsBgView.frame) + marginH, UI_View_Width - marginX * 4, 40); surebtn.titleLabel.font = [UIFont boldSystemFontOfSize:16]; [surebtn addTarget:self action:@selector(sureBtnClick) forControlEvents:UIControlEventTouchUpInside]; surebtn.backgroundColor = [UIColor orangeColor]; surebtn.layer.cornerRadius = 3.0; surebtn.clipsToBounds = YES; [self.view addSubview:surebtn]; }
3. 按鈕多選邏輯處理, 并上傳數(shù)據(jù)請(qǐng)求處理
/** * 按鈕多選處理 */ - (void)chooseMark:(UIButton *)btn { btn.selected = !btn.selected; if (btn.isSelected) { btn.backgroundColor = ZLSelectedColor; [self.selectedMarkArray addObject:self.markDict[btn.titleLabel.text]]; [self.selectedMarkStrArray addObject:btn.titleLabel.text]; } else { btn.backgroundColor = ZLUnselectedColor; [self.selectedMarkArray removeObject:self.markDict[btn.titleLabel.text]]; [self.selectedMarkStrArray removeObject:btn.titleLabel.text]; } } /** * 確認(rèn)接口請(qǐng)求處理 */ - (void)sureBtnClick { // 用戶選擇標(biāo)簽后就把值上傳, 也要傳給服務(wù)器下次直接請(qǐng)求回來(lái) // 按鈕數(shù)字標(biāo)識(shí)字符串 NSString *numStr = [self.selectedMarkArray componentsJoinedByString:@","]; // 按鈕文字字符串 NSString *str = [self.selectedMarkStrArray componentsJoinedByString:@","]; // 測(cè)試:拼接請(qǐng)求參數(shù) NSLog(@"按鈕數(shù)字標(biāo)識(shí)字符串:%@", numStr); NSLog(@"按鈕文字字符串:%@", str); }
