iOS调用系统的相册(包括,显示中文的标题)

首先在info.plist加上这一条这样就可以使我们调出来的相册显示出中文啦～

Localized resources can be mixed 设置为 YES。

下面我来简单介绍下，怎么调用系统相机和系统相册来更换图片～

首先，我们要遵守几个代理啦~

UIImagePickerControllerDelegate, UINavigationControllerDelegate, UIActionSheetDelegate

前两个是和调用相机和相册有关，后面这个是和下面弹出的框框有关～

点击头像触发下面这个方法

<pre name="code" class="objc">-(void)headImgChange:(id)sender{    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:@"从相册中选择", @"打开拍照", nil];    [actionSheet showInView:self.view];}

然后我们选择的时候会触发下面的方法~

#pragma mark - UIActionSheet Delegate-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{    switch (buttonIndex) {        case 0:        {            //从相册中选择            [self LocalPhoto];        }            break;        case 1:        {            //拍照            [self takePhoto];        }            break;    }}

<pre name="code" class="objc">//打开本地相册-(void)LocalPhoto{    UIImagePickerController *picker = [[UIImagePickerController alloc] init];        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;    picker.delegate = self;    //设置选择后的图片可被编辑    picker.allowsEditing = YES;    [self presentViewController:picker animated:YES completion:nil];}

<pre name="code" class="objc">//开始拍照(这个要用真机测试，模拟器测试会crash～)-(void)takePhoto{    UIImagePickerControllerSourceType sourceType = UIImagePickerControllerSourceTypeCamera;    if ([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera])    {        UIImagePickerController *picker = [[UIImagePickerController alloc] init];        picker.delegate = self;        //设置拍照后的图片可被编辑        picker.allowsEditing = YES;        picker.sourceType = sourceType;        [self presentViewController:picker animated:YES completion:nil];    }else    {    }}

最后我们从相册选择也好，拍照也好，完成后都会到这个代理方法里

//当选择一张图片后进入这里-(void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{    NSString *type = [info objectForKey:UIImagePickerControllerMediaType];    //当选择的类型是图片    if ([type isEqualToString:@"public.image"])    {        //先把图片转成NSData        UIImage* image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];        if (UIImagePNGRepresentation(image) == nil)        {            m_imgData = UIImageJPEGRepresentation(image, 1.0);            m_dataType = @"image/jpeg";        }else{            m_imgData = UIImagePNGRepresentation(image);            m_dataType = @"image/png";        }        //关闭相册界面        [picker dismissModalViewControllerAnimated:YES];        [self.headButton setBackgroundImage:image forState:UIControlStateNormal];        //开启上传//        [self uploadUserFace];    }}

基本完事了，欢迎大家多多交流.喜欢交流的朋友请加qq群:410033829，方便交流和跳槽～
