自定义一个类似UIAlertView的弹出框

这个是和UIAlertView类似,但是可以自定义view的样式废话不多说,上代码:

首先第一步:创建一个继承自View的类如:

#import <UIKit/UIKit.h>

@class <#你自己的类名#>;

@protocol PopupViewDelegate <NSObject>

- (void)popupView:(<#你自己的类名#>*)popupView ClickedButtonAtIndex:(NSInteger)buttonIndex;

@end

@interface <#你自己的类名#> : UIView

/**初始化View

 * title   * 提示内容

 * message * 需要显示的内容

 * cancelButtonTitle *取消按钮的文字

 * okButtonTitles *确认按钮的文字

 * delegate  * 当前代理者

 */

- (instancetype)initWithTitle:(NSString *)title message:(NSString *)message cancelButtonTitle:(NSString *)cancelButtonTitle okButtonTitles:(NSString *)okButtonTitles delegate:(id)delegate;

/**弹出该View*/

- (void)show;

 @property (nonatomic,strong)id <PopupViewDelegate>  delegate;

 @end

/**上方的方法直接贴到View的.h文件中就好,当然类名需要更改的*/

//屏幕宽度

#define SCREEN_WIDTH [UIScreen mainScreen].bounds.size.width

//获得屏幕高度

#define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height)

 #define kNoButtonW 120

#define kNoButtonH 35

#define kButtonRadius 15

#define kFontNameStrBold @"Helvetica-Bold"

#define kFontNameStrRegular @"Helvetica"

#import " <#你自己的类名#>"

@interface  <#你自己的类名#>()

/**中间黑色的View*/

@property (nonatomic,strong)UIView * blackeView;

/**提示框的Lable*/

@property (nonatomic,strong)UILabel * titleLable;

/**描述内容的Lable*/

@property (nonatomic,strong)UILabel * desLabel;

/**取消或者NO的button*/

@property (nonatomic,strong)UIButton * noButton;

/**YES或者OK的button*/

@property (nonatomic,strong)UIButton * yesButton;

@end

@implementation  <#你自己的类名#>

- (instancetype)initWithTitle:(NSString *)title message:(NSString *)message cancelButtonTitle:(NSString *)cancelButtonTitle okButtonTitles:(NSString *)okButtonTitles delegate:(id)delegate

{

    if (self = [super init]) {

        self.frame = CGRectMake(0, 0,SCREEN_WIDTH, SCREEN_HEIGHT);

        self.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:0.2];

        /**设置弹出View的动画*/

        [self setupWithBlackView];

        /**往黑色View中添加子控件*/

        [self setupWithAddControls];

        self.titleLable.text = title;

        self.desLabel.text = message;

}

    /**标题文本*/

    UILabel * titleLable = [[UILabel alloc]init];

    titleLable.numberOfLines = 0;

    titleLable.textAlignment = NSTextAlignmentCenter;

//    titleLable.backgroundColor = [UIColor redColor];

    titleLable.font = [UIFont fontWithName:kFontNameStrBold size:22];

    titleLable.textColor = [UIColor whiteColor];

    //设置NO的按钮frame

    CGFloat nobtnH = kNoButtonH;

    CGFloat nobtnW = kNoButtonW;

    self.noButton.frame = CGRectMake(10, CGRectGetMaxY(self.blackeView.bounds)-nobtnH-15, nobtnW, nobtnH);

        //设置YES的按钮frame

    /**根据判断来设置frame*/

    [self stupOrEmpty];

}

-(void)stupOrEmpty

{

    {//如果No按钮没有文字则只显示YES按钮

    }

}

-(void)yesOrNOButtonClcik:(UIButton*)buttonTag

{

        [self.delegate popupView:self ClickedButtonAtIndex:buttonTag.tag];

    }

    [UIView animateWithDuration:0.38 animations:^{

        self.alpha = 1;

        self.blackeView.transform = CGAffineTransformIdentity;

    }];

}

@end

/**上面这个就是放在.m里面了*/

<PopupViewDelegate>

接下来你只需要在你要响应的点击事件里面去导入这个View的头文件和遵守它的代理实现代理方法就可以了

PopupView * popupV = [[PopupView alloc]initWithTitle:@"Are You?" message:@"你猜我我猜你猜我猜你猜我是谁!" cancelButtonTitle:@"Helvetica" okButtonTitles:@"OK" delegate:self];

    [popupV show];

/**代理方法*/

- (void)popupView:(PopupView *)popupView ClickedButtonAtIndex:(NSInteger)buttonIndex{

    if (popupView.tag == 1) {

        NSLog(@"点击了取消按钮");

    }else{

        NSLog(@"点击了确认按钮");

    }

}

好了一个自定义的弹出框就搞定了!
