关于UIImagePickerController

在需要选取上传图片的时候可以使用UIImagePickrController;

使用的方法如下:

- (IBAction)headImageAdd:(id)sender {

    UIImagePickerController *imagePick=[[UIImagePickerController
alloc]init];

//设置数据源

    imagePick.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;

//实现代理,在代理方法中得到数据

    imagePick.delegate=self;

#warning 记录;

//    UIImagePickerController 的对象是不支持push的是能present

//    [self.navigationController pushViewController:imagePick animated:YES];

    [self
presentViewController:imagePick animated:YES
completion:nil];

    

}

#pragma pickController的代理实现

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary
*)editingInfo

{

    

}

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

{

    UIImage *image=info[UIImagePickerControllerOriginalImage];

//    [self.headImage setImage:image forState:UIControlStateNormal];

    [self.headImage
setBackgroundImage:image forState:UIControlStateNormal];

    [picker dismissViewControllerAnimated:YES
completion:nil];

}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker

{

    [picker dismissViewControllerAnimated:YES
completion:nil];

}

以上代码是从相册里选取,当然也可以用方式.

imagePick.sourceType苹果提供了3中方式

 UIImagePickerControllerSourceTypePhotoLibrary,图库

 UIImagePickerControllerSourceTypeCamera,照相机

 UIImagePickerControllerSourceTypeSavedPhotosAlbum,相册
