iOS中UIAlertView怎么用
这篇文章主要介绍iOS中UIAlertView怎么用，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！
NS_CLASS_DEPRECATED_IOS(2_0, 9_0, "UIAlertView is deprecated. Use UIAlertController with a preferredStyle of UIAlertControllerStyleAlert instead") __TVOS_PROHIBITED
大概意思是说9以后用UIAlertController代替UIAlertView，9以前还是UIAlertView
double version = [[UIDevice currentDevice].systemVersion doubleValue];//判定系统版本。
if(version>=9.0f){
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"提示" message:nil preferredStyle:UIAlertControllerStyleAlert];
[alertController addAction: [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
NSLog(@"确定");
}]];
[alertController addAction: [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
NSLog(@"取消");
}]];
[self presentViewController:alertController animated:YES completion:nil];
}else{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"提示" message:nil delegate:self cancelButtonTitle:nil otherButtonTitles:@"确定",@"取消", nil];
[alertView show];
}
#pragma mark UIAlertView 点击事件
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex NS_DEPRECATED_IOS(2_0, 9_0){
NSLog(@"%@",@(buttonIndex));
}
