淺談iPhone手機拍照功能和照片庫選取功能調用是本文要介紹的內容，內容不多，主要是以代碼實現，我們來看內容。

首先，你得實現UIImagePickerControllerDelegate,UINavigationControllerDelegate兩個代理

其次定義按鈕：

// 從相簿里上傳一張  
UIButton *btn1 = [UIButton buttonWithType: UIButtonTypeRoundedRect];  
btn1.frame = CGRectMake(60.0, 237.0, 200.0, 32.0);  
[btn1 setTitle:@"從媒體庫中選取圖片" forState:UIControlStateNormal];  
[btn1 addTarget:self action:@selector(picker) forControlEvents:UIControlEventTouchUpInside];  
UIButton *btn2 = [UIButton buttonWithType: UIButtonTypeRoundedRect];   
btn2.frame = CGRectMake(60.0, 290.0, 200.0, 32.0);  
[btn2 setTitle:@"從相機獲取圖片" forState:UIControlStateNormal];  
[btn2 addTarget:self action:@selector(picker1) forControlEvents:UIControlEventTouchUpInside]; 

實現按鈕方法：

// 從照片庫里面選取  
 
-(void)picker  
 
{  
 
imagepicker = [[UIImagePickerController alloc] init];  
 
imagepicker.delegate = self;  
 
imagepicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;  
imagepicker.modalTransitionStyle = UIModalTransitionStyleCoverVertical;  
imagepicker.allowsEditing = YES;  
[self presentModalViewController:self.imagepicker animated:YES];  
}  
// 從相機獲取  
-(void)picker1  
{  
imagepicker = [[UIImagePickerController alloc] init];  
imagepicker.delegate = self;  
imagepicker.sourceType = UIImagePickerControllerSourceTypeCamera;  
imagepicker.modalTransitionStyle = UIModalTransitionStyleCoverVertical;  
imagepicker.allowsEditing = YES;  
[self presentModalViewController:self.imagepicker animated:YES];  
} 

實現代理方法：

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