Iphone利用UIImagePickerController调用系统照相机

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:









最后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];

}
