ObjectiveC-ui按钮保持高亮显示/选中状态,背景颜色和字体颜色在高亮显示/选中时发生变化

我能够实现你正在工作的功能,下面是我是如何做到的。

- (IBAction)btnPressed:(UIButton*)sender {

/* Below for loop works as a reset for setting the default colour of button and to not select the same one twice*/
for (UIButton* button in buttons) {
    [button setSelected:NO];
    [button setBackgroundColor:[UIColor whiteColor]];
    [button setUserInteractionEnabled:true];
// [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [button setTitleColor:[UIColor blackColor] forState:UIControlStateSelected];
}

NSInteger tag = sender.tag;        // Here we get the sender tag, which we can use for our needs. Also we can directly use the sender and get the title or whatsoever needed.

/*Now below line works as a toggle for the button where multiple buttons can't be selected at the same time.*/
sender.selected = ! sender.selected;      

if(sender.selected)
{
/* Here we set the color for the button and handle the selected function*/
    [sender setSelected:YES];
    [sender setUserInteractionEnabled:false];
    [sender setBackgroundColor:[UIColor magentaColor]];
}
}

您也可以使用“”为按钮添加自定义层发送方.层“财产。

-(IBAction)BTN按下:(UIButton*)发送器;

#import "ViewController.h"

@interface ViewController ()
@property (weak, nonatomic) IBOutlet UIView *mainViewOL;
@property (weak, nonatomic) IBOutlet UIButton *btn1;
@property (weak, nonatomic) IBOutlet UIButton *btn2;
@property (weak, nonatomic) IBOutlet UIButton *btn3;
@property (weak, nonatomic) IBOutlet UIButton *btn4;
@property (weak, nonatomic) IBOutlet UIButton *btn5;
@property (weak, nonatomic) IBOutlet UIButton *btn6;
@property (weak, nonatomic) IBOutlet UIButton *btn7;
@property (weak, nonatomic) IBOutlet UIButton *btn8;
@property (weak, nonatomic) IBOutlet UIButton *btn9;

@end

@implementation ViewController

NSArray* buttons;

- (void)viewDidLoad {
    [super viewDidLoad];

    buttons = [NSArray arrayWithObjects:_btn1, _btn2, _btn3,_btn4,_btn5,_btn6,_btn7,_btn8,_btn9,nil];

    self.mainViewOL.layer.shadowRadius  = 5;
    self.mainViewOL.layer.shadowColor   = [UIColor colorWithRed:211.f/255.f green:211.f/255.f blue:211.f/255.f alpha:1.f].CGColor;
    self.mainViewOL.layer.shadowOffset  = CGSizeMake(0.0f, 0.0f);
    self.mainViewOL.layer.shadowOpacity = 0.9f;
    self.mainViewOL.layer.masksToBounds = NO;

    /* I Have added the 9 button's in an array and used it to reduce the lines of code and for easy understanding as well*/
    for (UIButton* button in buttons) {
        button.layer.borderColor = [UIColor lightGrayColor].CGColor;
        button.layer.borderWidth =1.0f;
    }
}

- (IBAction)btnPressed:(UIButton*)sender {
    for (UIButton* button in buttons) {
        [button setSelected:NO];
        [button setBackgroundColor:[UIColor whiteColor]];
        [button setUserInteractionEnabled:true];
     // [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];        //Based on your needs and colour variant you cant add properties to the button for different control states.
        [button setTitleColor:[UIColor blackColor] forState:UIControlStateSelected];
    }

    NSInteger tag = sender.tag;

    sender.selected = ! sender.selected;


    if(sender.selected)
    {
        [sender setSelected:YES];
        [sender setUserInteractionEnabled:false];
        [sender setBackgroundColor:[UIColor purpleColor]];
        sender.backgroundColor = [UIColor magentaColor];
    }
}

@end

希望这有帮助。

从理论上讲,您可以执行以下操作:

1. 将所有按钮存储在一个数组中(一个实例变量)

按钮的构造函数函数如下所示:

-(UIButton *)newButtonWithTitle:(NSString *)title fontSize:(NSInteger)fontSize {
    UIColor *selectedButtonColor = [UIColor colorWithRed:1.0 green:0.2 blue:0.2 
    alpha:0.5];

    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    [button setTitle:title forState:UIControlStateNormal];
    [button setTitleColor:selectedButtonColor forState:UIControlStateHighlighted];
    [button setTitleColor:selectedButtonColor forState:UIControlStateSelected];
    button.titleLabel.font = [UIFont systemFontOfSize:16 weight:UIFontWeightRegular];
    button.layer.borderColor = [UIColor lightGrayColor].CGColor;
    button.layer.borderWidth = 1.0;

    [button addTarget:self action:@selector(scheduleButtonAction:) forControlEvents:UIControlEventTouchUpInside];
    return button;
}

按钮动作功能可以是:

-(void)scheduleButtonAction:(UIButton *)button {
    button.selected = YES;
    [self.buttons enumerateObjectsUsingBlock:^(UIButton *aButton, NSUInteger idx, BOOL * _Nonnull stop) {
        if (![aButton isEqual:button]) {
            aButton.selected = NO;
        }
    }];
}

但是

user10277996暗示了一种更好的布局方式,即使用集合视图。这将使您能够将关注点分开:

1. 决定按钮(单元格)数量的数据源 创建(以及它们应该包含哪些数据)
2. 单元的构造函数类,在该类中定义设计 一旦
3. 一个布局类,在该类中定义如何布局按钮。

您应该花一两天时间真正熟悉UICollectionView,因为它是iOS中最强大、最有用的类之一。

如果您想深入了解,请查看以下资源(虽然不是解决特定问题所必需的): https://www.objc.io/issues/3-views/collection-view-layouts/ https://ashfurrow.com/uicollectionview-the-complete-guide/

UIButton *customButton = [UIButton buttonWithType:UIButtonTypeCustom];

或在接口生成器中设置此属性。

override var isSelected: Bool `{
         willSet{
                   super.isSelected = newValue

          // put button background color value as per selected state`

您可以通过tag控件获取任何按钮并控制任何按钮。
