UIImagePickerController 使用示例

从图片库获取数据

- (IBAction)doPhotoAlbumBtn:(UIButton *)sender {
    UIImagePickerController* ipController = [[UIImagePickerController alloc] init];
    [self presentViewController:ipController animated:YES completion:nil];
    [ipController setDelegate:self];
}

 

从相机获取数据

UIImagePickerController* ipController = [[UIImagePickerController alloc] init];

if ([[[UIDevice currentDevice] model] rangeOfString:@"Sim"].location == NSNotFound) {
    [ipController setSourceType:UIImagePickerControllerSourceTypeCamera];
    [ipController setDelegate:self];
    [self presentViewController:ipController animated:YES completion:nil];
}

 

实现下面的代理方法

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    NSLog(@"%@", [info objectForKey:UIImagePickerControllerOriginalImage]);

    UIImage* img = [info objectForKey:UIImagePickerControllerOriginalImage];
    // TODO
    [self dismissViewControllerAnimated:NO completion:nil];
    // TODO
}
