iPhone手机拍照功能和照片库选取功能调用

浅谈iPhone手机拍照功能和照片库选取功能调用是本文要介绍的内容，内容不多，主要是以代码实现，我们来看内容。

首先，你得实现UIImagePickerControllerDelegate,UINavigationControllerDelegate两个代理

其次定义按钮：

// 从相簿里上传一张

1. UIButton *btn1 = [UIButton buttonWithType: UIButtonTypeRoundedRect];
2. btn1.frame = CGRectMake(60.0, 237.0, 200.0, 32.0);
3. [btn1 setTitle:@"从媒体库中选取图片" forState:UIControlStateNormal];
4. [btn1 addTarget:self action:@selector(picker) forControlEvents:UIControlEventTouchUpInside];
5. UIButton *btn2 = [UIButton buttonWithType: UIButtonTypeRoundedRect];
6. btn2.frame = CGRectMake(60.0, 290.0, 200.0, 32.0);
7. [btn2 setTitle:@"从相机获取图片" forState:UIControlStateNormal];
8. [btn2 addTarget:self action:@selector(picker1) forControlEvents:UIControlEventTouchUpInside];

实现按钮方法：

// 从照片库里面选取

-(void)picker
{
imagepicker = [[UIImagePickerController alloc] init];
imagepicker.delegate = self;
imagepicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagepicker.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
imagepicker.allowsEditing = YES;
[self presentModalViewController:self.imagepicker animated:YES];
}
// 从相机获取
-(void)picker1
{
imagepicker = [[UIImagePickerController alloc] init];
imagepicker.delegate = self;
imagepicker.sourceType = UIImagePickerControllerSourceTypeCamera;
imagepicker.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
imagepicker.allowsEditing = YES;
[self presentModalViewController:self.imagepicker animated:YES];
}

实现代理方法：

// 初始化选取
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingImage:(UIImage *)image
editingInfo:(NSDictionary *)editingInfo
{
myImageView.image = image;
[[picker parentViewController] dismissModalViewControllerAnimated:YES];
}
// 完成选取

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