IPhone應用開發(fā)之UIImagePickerController調用系統(tǒng)照相機是本文要介紹的內容，不多說，我們來看內容。iphone api中提供了調用系統(tǒng)照相機的接口,我們只需調用相應的界面,即刻在自己的程序中獲取相機圖片.下面是一個非常簡單的調用系統(tǒng)照相機的例子.

相應的界面如下:

***可以編輯圖片和使用相應的圖片.

下面是主要代碼:

- (void) addPicEvent   
{   
    //先設定sourceType為相機，然后判斷相機是否可用（ipod）沒相機，不可用將sourceType設定為相片庫   
    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];   
}
