因为项目需求，自定义弹出视图的基础上加一些用户体验更佳的动画和友情文字以及图片提示等，就有了写了这篇博客，一为方便自己以后在其他项目中复用二为更多开发者拷贝使用，若有书写代码不足之处欢迎批评指正。 先看下我的Demo示例运行效果图如下： 弹框动画效果图.png实现文件只有一个类：（QDImageAlertView.h 和 QDImageAlertView.m） 1.QDImageAlertView.h头文件代码如下： #import @interface QDImageAlertView : UIView //初始化 + (instancetype)alertWithFrame:(CGRect)frame imageName:(NSString *)imageName title:(NSString *)title message:(NSString *)message; //弹窗 - (void)alert; @property (nonatomic,copy) void(^confirmButtonBlock)(); @property (nonatomic,copy) void(^cancelButtonBlock)(); @end 2.QDImageAlertView.m实现文件代码如下： #import "QDImageAlertView.h" #import "Masonry.h" const CGFloat imageAlertViewWidthRatio = 0.655; //宽度系数 const CGFloat imageAlertViewHeightRatio = 0.386; //高度系统 @interface QDImageAlertView () @property (nonatomic, weak) UIView *bgView; @property (nonatomic, weak) UIImageView *bgImageView; @property (nonatomic, weak) UIImageView *iconImageView;//顶部icon图 @property (nonatomic, weak) UILabel *titleLabel;//标题 @property (nonatomic, weak) UILabel *messageLabel;//消息内容 @property (nonatomic, weak) UIView *horizontalLineV;//水平线 @property (nonatomic, weak) UIView *verticalLineV;//垂直线 @property (nonatomic, weak) UIButton *confirmButton;//确认按钮 @property (nonatomic, weak) UIButton *cancleButton;//取消按钮 @property (nonatomic, copy) NSString *title; @property (nonatomic, copy) NSString *message; @property (nonatomic, copy) NSString *imageName; @end @implementation QDImageAlertView + (instancetype)alertWithFrame:(CGRect)frame imageName:(NSString *)imageName title:(NSString *)title message:(NSString *)message{ QDImageAlertView *alert = [[self alloc] initWithFrame:frame]; alert.imageName = imageName; alert.title = title; alert.message = message; return alert; } - (void)alert{ [UIApplication.sharedApplication.keyWindow addSubview:self]; } - (instancetype)initWithFrame:(CGRect)frame{ self = [super initWithFrame:frame]; if (self) { [self setUpUI]; } return self; } - (void)setUpUI{ //大背景视图 UIView *bgView = [[UIView alloc] initWithFrame:UIApplication.sharedApplication.keyWindow.bounds]; bgView.backgroundColor = [UIColor colorWithWhite:0 alpha:0.5];

[alertView setConfirmButtonBlock:^{ NSLog(@"正在删除，请稍后"); }]; [alertView alert];如果您希望在你的项目中直接使用，那就直接拷贝就行 如果觉得还不够具体，后期考虑将代码上传github与分享源码，希望深层交流的童鞋加我qq:1107160410，我们一起探讨，感谢您看到这里，如方便的话点个赞，我会更加努力。 欢迎点击下篇博客链接 http://www.jianshu.com/p/a03ab31ffc88查看更加相关内容，可能会帮到您。 |
