IOS 8 前
UIAlertView创建提示框
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.25 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
UIAlertView *alertV = [[UIAlertView alloc]initWithTitle:@"您的幸运号码是:" message:@"1,2,3,4,5,6" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:nil, nil];
//显示
[alertV show];
});
IOS 8
UIAlertViewController
1、设置代理调用
//执行代理方法
if ([self.delegate respondsToSelector:@selector(modalWithAlertController:)]) {
//有方法则执行
[self.delegate modalWithAlertController:self];
}
2、控制器实现
-(void)modalWithAlertController:(CZWheelVIew *)alertcontroller
{
//创建提示框控制器
UIAlertController *alertC = [UIAlertController alertControllerWithTitle:@"您的幸运号码是:" message:@"1,2,3,4,5,6" preferredStyle:UIAlertControllerStyleAlert];
//创建一个动作
UIAlertAction *alertA = [UIAlertAction actionWithTitle:@"确认" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
//继续匀速旋转
[self.wheelView startRotate];
}];
//动作添加给提示框控制器
[alertC addAction:alertA];
//控制器弹出控制器
[self presentViewController:alertC animated:YES completion:nil];
}
