调用系统相册-白红宇

遇到一个问题：相机的界面总是显示英文。查了下资料发现在 info.plist里面添加Localized resources can be mixed = YES ，表示是否允许应用程序获取框架库内语言（前题是手机要设置为中文）

1.首先遵循协议


    
     复制代码

2.根据需要选择调用相机/相册

这里我们一般会使用UIActionSheet中（需要遵循UIActionSheetDelegate协议）

UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:@"拍照",@"从相册选择", nil];actionSheet.actionSheetStyle = UIActionSheetStyleDefault;[actionSheet showInView:self.view];复制代码

UIActionSheetDelegate

根据被点击的按钮做出反应，0对应destructiveButton，之后的button依次排序

#pragma mark - UIActionSheetDelegate- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {        if (buttonIndex == 0) {                NSLog(@"拍照");        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {                        UIImagePickerController *imageController = [[UIImagePickerController alloc] init];            [imageController setSourceType:UIImagePickerControllerSourceTypeCamera];    // 设置类型            [imageController setDelegate:self];            [imageController setAllowsEditing:YES];    // 设置是否可以编辑            [self presentViewController:imageController animated:YES completion:nil];        }else{                        [self showAlertWith:@"提示" andMessage:@"哎呀，当前设备没有摄像头。"];        }    }else if (buttonIndex == 1) {                NSLog(@"相册");        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {            UIImagePickerController *imageController = [[UIImagePickerController alloc] init];            [imageController setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];// 设置为相册类型            [imageController setDelegate:self];            [imageController setAllowsEditing:YES];            [self presentViewController:imageController animated:YES completion:nil];        }else{                        [self showAlertWith:@"提示" andMessage:@"图片库不可用。"];        }    }}复制代码

UIImagePickerControllerDelegate

当获取到照片或视频后调用

#pragma mark UIImagePickerControllerDelegate- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {        NSLog(@"获取成功");    UIImage *pickedImage = nil;    if ([picker allowsEditing]) {        pickedImage = [info objectForKey:UIImagePickerControllerEditedImage];    } else {        pickedImage = [info objectForKey:UIImagePickerControllerOriginalImage];    }    NSString *imagePath = [[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] stringByAppendingPathComponent:@"image.png"];    [UIImagePNGRepresentation(pickedImage) writeToFile:imagePath atomically:YES];     self.imageView.image = [UIImage imageNamed:pickedImage];    // 使用}复制代码
