iOS8之后UIAlertView被弃用 UIAlertController成功上位

如图所示当你UIAlert时 UIAlertView被划了一道红线说明oc已经弃用了UIAlertView 随之而来的是UIAlertController

那么UIAlertController怎么用呢会不会很麻烦

别急看代码

我现在需要一个弹出框然后选择图片的来源是从相册获取还是拍照

代码点击已经设置好的icon 弹框

#pragma mark --更改icon--- (void)changeIconImage{        UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"选择图片来源" message:nil preferredStyle:UIAlertControllerStyleAlert];        UIAlertAction *photography = [UIAlertAction actionWithTitle:@"拍照" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {        [self photography];    }];    UIAlertAction *photoSelect = [UIAlertAction actionWithTitle:@"从相册选取" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {        [self photoSelect];    }];    UIAlertAction *cancel = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleDefault handler:nil];        [alert addAction:photography];    [alert addAction:photoSelect];    [alert addAction:cancel];        [self presentViewController:alert animated:YES completion:nil];    //    UIActionSheet *as = [[UIActionSheet alloc] initWithTitle:@"选择图片来源" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:@"从相册选取", @"拍照", nil];//    //    [as showInView:self.view];    }

#pragma mark --photography拍照--- (void)photography{        UIImagePickerController *ipc = [[UIImagePickerController alloc] init];        ipc.navigationBar.backgroundColor = [UIColor redColor];    //判断设备是否支持这种sourcetype    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){        ipc.sourceType = UIImagePickerControllerSourceTypeCamera;    }    ipc.delegate = self;    //是否允许编辑    ipc.allowsEditing = YES;    [self presentViewController:ipc animated:YES completion:nil];    }- (void)photoSelect{        UIImagePickerController *ipc = [[UIImagePickerController alloc] init];    ipc.navigationBar.backgroundColor = [UIColor redColor];    //判断设备是否支持这种sourcetype    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeSavedPhotosAlbum]){        ipc.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;    }    ipc.delegate = self;    //是否允许编辑    ipc.allowsEditing = YES;        [self presentViewController:ipc animated:YES completion:nil];}

#pragma mark---ImagePickerControllerDelegate---- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary<NSString *,id> *)info{    UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage];    iconImageView.image = image;    [picker dismissViewControllerAnimated:NO completion:nil];}

这三段代码连起来问题就解决了不过亲要记得加上 UIImagePickerControllerDelegate,UINavigationControllerDelegate 这两个

下面解决问题的图片测试图片成功替换没任何问题
