話不多說，首先看效果圖
1、定義UIView的擴展類
UIView+DBExtension.h
import <UIKit/UIKit.h>
@interface UIView (DBExtension)
@property (nonatomic, assign) CGFloat x;
@property (nonatomic, assign) CGFloat y;
@property (nonatomic, assign) CGFloat centerX;
@property (nonatomic, assign) CGFloat centerY;
@property (nonatomic, assign) CGFloat width;
@property (nonatomic, assign) CGFloat height;
@property (nonatomic, assign) CGSize size;
@property (nonatomic, assign) CGPoint origin;
@end
UIView+DBExtension.m
@implementation UIView (DBExtension)
// set
-
(void)setX:(CGFloat)x {
CGRect frame = self.frame;
frame.origin.x = x;
self.frame = frame;
} -
(void)setY:(CGFloat)y {
CGRect frame = self.frame;
frame.origin.y = y;
self.frame = frame;
} -
(void)setCenterX:(CGFloat)centerX {
CGPoint center = self.center;
center.x = centerX;
self.center = center;
} -
(void)setCenterY:(CGFloat)centerY {
CGPoint center = self.center;
center.y = centerY;
self.center = center;
} -
(void)setWidth:(CGFloat)width {
CGRect frame = self.frame;
frame.size.width = width;
self.frame = frame;
} -
(void)setHeight:(CGFloat)height {
CGRect frame = self.frame;
frame.size.height = height;
self.frame = frame;
} -
(void)setSize:(CGSize)size {
CGRect frame = self.frame;
frame.size = size;
self.frame = frame;
} -
(void)setOrigin:(CGPoint)origin {
CGRect frame = self.frame;
frame.origin = origin;
self.frame = frame;
}
// get
(CGFloat)x {
return self.frame.origin.x;
}(CGFloat)y {
return self.frame.origin.y;
}(CGFloat)centerX {
return self.center.x;
}(CGFloat)centerY {
return self.center.y;
}(CGFloat)width {
return self.frame.size.width;
}(CGFloat)height {
return self.frame.size.height;
}(CGSize)size {
return self.frame.size;
}(CGPoint)origin {
return self.frame.origin;
}
@end
其次
首先實現多選功能
// 設置多選視圖
-
(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];// 循環創建按鈕
NSInteger maxCol = 3;
for (NSInteger i = 0; i < 5; i++) {UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom]; btn.backgroundColor = 自己設置的顏色; 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: 按鈕標題數組 [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];
}
/**
- 按鈕多選處理
*/
-
(void)chooseMark:(UIButton *)btn {
btn.selected = !btn.selected;
if (btn.isSelected) {
btn.backgroundColor = 自己設置的顏色;
[self.selectedMarkArray addObject:self.markDict[btn.titleLabel.text]];
[self.selectedMarkStrArray addObject:btn.titleLabel.text];
} else {
btn.backgroundColor = 自己設置的顏色;
[self.selectedMarkArray removeObject:self.markDict[btn.titleLabel.text]];
[self.selectedMarkStrArray removeObject:btn.titleLabel.text];
}
}
最后實現單選按鈕
// 設置單選視圖
-
(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, self.markArray.count *btnH + self.markArray.count/3 * (btnH + marginX))];
btnsBgView.backgroundColor = [UIColor whiteColor];
[self.view addSubview:btnsBgView];// 循環創建按鈕
NSInteger maxCol = 3;
for (NSInteger i = 0; i < self.markArray.count; i++) {UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom]; btn.backgroundColor = [UIColor lightGrayColor]; 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];}
//獲取最后一個按鈕的偏移量
UIButton *lastBtn = _btnArray[_btnArray.count - 1];
NSLog(@"%f",lastBtn.y);
// 創建完btn后再判斷是否能選擇(之前是已經選取過的)
// 假數據:之前已經上傳16時,則回顯16
// for (UIButton *btn in btnsBgView.subviews) {
// if ([@"16" isEqualToString:btn.titleLabel.text]) {
// btn.selected = YES;
// btn.backgroundColor = ZLSelectedColor;
// break;
// }
// }
}
/**
- 數字按鈕單選處理
*/
-
(void)chooseMark:(UIButton *)sender {
NSLog(@"點擊了%@", sender.titleLabel.text);self.selectedBtn = sender;
sender.selected = !sender.selected;
for (NSInteger j = 0; j < [self.btnArray count]; j++) {
UIButton *btn = button數組 [j] ;
if (sender.tag == j) {
btn.selected = sender.selected;
} else {
btn.selected = NO;
}btn.backgroundColor = [UIColor lightGrayColor];}
// 根據tag值去判斷
UIButton *btn = self.btnArray[sender.tag];
if (btn.selected) {btn.backgroundColor = [UIColor blueColor];} else {
btn.backgroundColor = [UIColor lightGrayColor];}
}
希望對你有所幫助！
