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=[[UIImagePickerControlleralloc]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];

[selfpresentViewController:imagePick animated:YEScompletion: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.headImagesetBackgroundImage:image forState:UIControlStateNormal];

[picker dismissViewControllerAnimated:YEScompletion:nil];

}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker

{

[picker dismissViewControllerAnimated:YEScompletion: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
