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

}];
}
@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！
