前两天在工作中遇到一个对过的选项进行选择,一开始的时候,我是一个选项一个选项的添加,发现代码的重复率实在是太高了,所以,我就封装了一个方法,这里我对这个方法的参数进行一下讲解

--------------------

*  ###### titleString:本参数是弹窗的标题 ######
 *  ###### array:本参数是一个数组对象,里面存储的是我们所需要的所有的选项, ######
 *  ###### label:这个label对象是我们需要显示我们选择的是那个一个选项,这里我们可以对label进行手势的添加,来实现的这个事件的点击 ######

-(void)addAlertViewControllerWithTitle:(NSString *)titleString menssage:(NSArray *)array showlable:(UILabel *)label{
        
        UIAlertController *  alertCtr2 = [UIAlertController alertControllerWithTitle:titleString message:nil preferredStyle:UIAlertControllerStyleAlert];
        
        for (int i = 0; i< array.count; i++) {
            
            NSString *string = array[i];
            // Create the actions.
            UIAlertAction *ButtonAction = [UIAlertAction actionWithTitle:string style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
                
                label.text = string;
                
            }];
            
            [alertCtr2 addAction:ButtonAction];
            
        }
        
        [self presentViewController:alertCtr2 animated:YES completion:nil];
        
    }

#### 多弹窗选择菜单使用范例 ####

--------------------

这里我还是在ViewController中进行范例的演示.给看管吧代码复制到自己Demo种查看就好

#import "ViewController.h"
    
    @interface ViewController ()
    
    @property(nonatomic,strong)UILabel *label;
    
    @end
    
    @implementation ViewController
    
    - (void)viewDidLoad {
        [super viewDidLoad];
    
        _label = [[UILabel alloc]initWithFrame:CGRectMake(100, 100, 200, 100)];
        
        _label.text = @"点击选择选项";
        
        //lable添加一个tap手势
        UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(presentChooseAlertView)];
        
        _label.userInteractionEnabled = YES;
        
        [_label addGestureRecognizer:tap];
        
        
        [self.view addSubview:_label];
        
    
    }
    
    
    -(void)presentChooseAlertView{
    
    
        [self addAlertViewControllerWithTitle:@"成为一个程序猿的必备条件" menssage:@[@"灵活的头脑",@"傲娇的内心",@"读过<<活着>>"] showlable:_label];
    
    
    }
    
    -(void)addAlertViewControllerWithTitle:(NSString *)titleString menssage:(NSArray *)array showlable:(UILabel *)label{
        
        UIAlertController *  alertCtr2 = [UIAlertController alertControllerWithTitle:titleString message:nil preferredStyle:UIAlertControllerStyleAlert];
        
        for (int i = 0; i< array.count; i++) {
            
            NSString *string = array[i];
            // Create the actions.
            UIAlertAction *ButtonAction = [UIAlertAction actionWithTitle:string style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
                
                label.text = string;
                
            }];
            
            [alertCtr2 addAction:ButtonAction];
            
        }
        
        [self presentViewController:alertCtr2 animated:YES completion:nil];
        
    }
    
    @end
