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
