iphone使用照片管理器，能从本地上传照片或者打开摄像头拍照，获取相片并编辑。

一、从头文件中添加UIImagePickerControllerDelegate协议

二、添加button事件，触发照片管理器

- (IBAction)getphoto:(id)sender {

   UIImagePickerController *picker=[[UIImagePickerController alloc]init];
    picker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
    picker.allowsEditing=YES;
    picker.delegate=self;
    [self presentModalViewController:picker animated:YES];
    [self.view addSubview:picker.view];

}

//保存获取的照片

-(void)saveImage:(UIImage *)image{
    NSLog(@"baocun");
    UIImageView *imageview=[[UIImageView alloc]initWithImage:image];

    [self.view addSubview:imageview];
}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
[picker dismissModalViewControllerAnimated:YES];
UIImage *image=[info objectForKey:UIImagePickerControllerEditedImage];//获取编辑后的照片
    UIImage *image1=[info objectForKey:UIImagePickerControllerOriginalImage];//获取未编辑的照片
[self performSelector:@selector(saveImage:)withObject:image afterDelay:0.5];//延迟0.5秒获取照片

}
-(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker{
[picker dismissModalViewControllerAnimated:YES];
}
