1 调用相机并且上传照片的方法
#import "ViewController.h" #import "AFNetworking.h" @interface ViewController () <UIActionSheetDelegate,UIImagePickerControllerDelegate,UINavigationControllerDelegate> @property (weak, nonatomic) IBOutlet UIImageView *imageView; @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. } - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"请选择照片" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:@"相机",@"相册", nil]; /** * window代表着最高处,所有能看到的view,后面都是window。 * 当push相机控制器的时候,self.view就自动移除了。而当dismiss控制器的时候,因为self.view移除了,所有sheet无法寄居在view的上面,而固定在self.view.window,就可以保证,sheet一定在view视图上 */ [sheet showInView:self.view.window]; } -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { UIImagePickerController *ipc = [[UIImagePickerController alloc] init]; ipc.delegate = self; ipc.allowsEditing = YES; //相片是否可编辑 switch (buttonIndex) { case 0: if (![UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]) return; ipc.sourceType = UIImagePickerControllerSourceTypeCamera; break; case 1: if (![UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypePhotoLibrary]) return; ipc.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; break; default: return; break; } [self presentViewController:ipc animated:YES completion:nil]; } /** * 选择完照片后调用的方法 * * * @param info 所有相片的信息都在这个字典 */ -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { [self dismissViewControllerAnimated:YES completion:nil]; //从字典key获取image的地址 UIImage *image = info[UIImagePickerControllerOriginalImage]; self.imageView.image = image; } - (IBAction)upload:(UIButton *)sender { AFHTTPRequestOperationManager *mrg = [[AFHTTPRequestOperationManager alloc] init]; NSMutableDictionary *params = [NSMutableDictionary dictionary]; params[@"username"] = @"123"; NSString *url = @"http://192.168.130.110:8080/MJServer/upload"; /** * 上传时候调用的方法 * * params post的参数,字典 * formData formData是post上去的数据 * name 服务器接受文件的名字 * fileName 文件的名字 */ [mrg POST:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { NSData *data = UIImageJPEGRepresentation(self.imageView.image, 1.0); [formData appendPartWithFileData:data name:@"file" fileName:@"1.jpg" mimeType:@"image/jpeg"]; } success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"上传成功"); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"上传失败"); }]; } @end
2 手动存储相片到相册
for (int i = 0; i<=9; i++) { UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:@"00%d.png", i]]; UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil); NSLog(@"%@", image); [NSThread sleepForTimeInterval:1]; //存储不可以过快 }
3 按钮文字设置成中文
info.plist 中添加Localized resources can be mixed 设置为YES
4 图片选择控制器
当想自己写一个图片选择控制器的时候,需要利用AssetsLibrary.framework,利用这个框架获得所有的相册图片
