iPhone应用开发之调用系统照相机

IPhone应用开发之UIImagePickerController调用系统照相机是本文要介绍的内容，不多说，我们来看内容。iphone api中提供了调用系统照相机的接口,我们只需调用相应的界面,即刻在自己的程序中获取相机图片.下面是一个非常简单的调用系统照相机的例子.

相应的界面如下:

***可以编辑图片和使用相应的图片.

下面是主要代码:

- (void) addPicEvent   
{   
    //先设定sourceType为相机，然后判断相机是否可用（ipod）没相机，不可用将sourceType设定为相片库   
    UIImagePickerControllerSourceType sourceType = UIImagePickerControllerSourceTypeCamera;   
    if (![UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]) {   
        sourceType = UIImagePickerControllerSourceTypePhotoLibrary;   
    }     
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];   
    picker.delegate = self;   
    picker.allowsEditing = YES;   
    picker.sourceType = sourceType;   
    [self presentModalViewController:picker animated:YES];   
    [picker release];   
}   
- (void)saveImage:(UIImage *)image {   
    NSLog(@"保存");   
}   
#pragma mark –   
#pragma mark Camera View Delegate Methods   
- (void)imagePickerController:(UIImagePickerController *)picker   
didFinishPickingMediaWithInfo:(NSDictionary *)info {   
    [picker dismissModalViewControllerAnimated:YES];   
    UIImage *image = [[info objectForKey:UIImagePickerControllerEditedImage] retain];   
    [self performSelector:@selector(saveImage:)   
               withObject:image   
               afterDelay:0.5];   
}   
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {   
    [picker dismissModalViewControllerAnimated:YES];   
}
