Question

我想学习如何让用户在其他设备上拍照。

我的问题是，从下面开始，用户将idPhoto连接到iduser字段，是否可以获取发布照片的用户的deviceid并在该用户设备上异步运行snapStillImage，考虑到它是目前非常IdPhoto执行segue选择器到该照片的全屏图像？在拍摄pic之后用于全屏幕的当前方法如下。我想知道是否可以让用户拍下他们选择的其他用户的照片。我想在选择发布的照片时发生这种情况。所有发布的照片都连接到数据库中的IdUser以及IdPhoto。

  -(void)didSelectPhoto:(PhotoView*)sender {
//photo selected - show it full screen
[self performSegueWithIdentifier:@"ShowPhoto" sender:[NSNumber numberWithInt:sender.tag]];
}
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([@"ShowPhoto" compare: segue.identifier]==NSOrderedSame) {
    StreamPhotoScreen* streamPhotoScreen = segue.destinationViewController;
    streamPhotoScreen.IdPhoto = sender;
}
}

StreamPhoto屏幕，用户点击拍摄并上传的图像的jpeg拇指的当前结果，在此视图控制器中以全屏显示图片。

#import "StreamPhotoScreen.h"
#import "API.h"
@implementation StreamPhotoScreen
@synthesize IdPhoto;
-(void)viewDidLoad {
API* api = [API sharedInstance];
//load the caption of the selected photo
[api commandWithParams:[NSMutableDictionary dictionaryWithObjectsAndKeys:@"stream", @"command", IdPhoto,@"IdPhoto", nil] onCompletion:^(NSDictionary *json) {
    //show the text in the label
    NSArray* list = [json objectForKey:@"result"];
    NSDictionary* photo = [list objectAtIndex:0];
    lblTitle.text = [photo objectForKey:@"title"];
}];
//load the big size photo
NSURL* imageURL = [api urlForImageWithId:IdPhoto isThumb:NO];
[photoView setImageWithURL: imageURL];
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
-(void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
}
@end

[UIDevice currentDevice]只是获取包含您所在设备属性的对象的共享实例（如单例）。该名称并不意味着暗示您可以访问其他设备（即[UIDevice someOtherDevice]）。
