小编Azi*_*lah的帖子

我有一个桌面应用程序,它有一个C++后端和一个HTML5/JS前端.我们目前不得不使用Google V8或Mac Webview和Objective-C来允许Javascript和C++进行通信.有没有办法让他们在没有中间件的情况下直接相互交谈？

试图完成:

1. 分享变量.
2. 从C++调用函数到JS.
3. 从JS到C++的调用函数.

我试过谷歌搜索,一切都指向上述解决方案.

我正在尝试在Google Calendar API上执行简单的freebusy查询.我的授权一切工作正常,可以查看用户日历列表等.当我尝试提交忙/闲查询时,我得到400错误(据我所知)没有关于它的详细信息不喜欢.

在我自己的代码和使用Google Calendar API"试用"功能时都是如此.

这是我的请求(使用Try It小部件创建)和响应:Request

我在AppDelegate文件中使用Swift在我的应用程序中添加了CLLocationManager.

在Appdelegate.swift文件中,

import CoreLocation
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, CLLocationManagerDelegate {
var locationManager: CLLocationManager!

在didbecomeActive方法中:

func applicationDidBecomeActive(application: UIApplication) {
    if((locationManager) != nil)
    {
        locationManager.stopMonitoringSignificantLocationChanges()
        locationManager.delegate = nil
        locationManager = nil
    }
    locationManager = CLLocationManager()
    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.activityType = CLActivityType.OtherNavigation
    locationManager.requestAlwaysAuthorization()
    locationManager.startMonitoringSignificantLocationChanges()
}

如果我使用startUpdatingLocation,didUpdateLocations方法被调用,但不是startMonitoringSignificantLocationChanges.

为什么没有被要求startMonitoringSignificantLocationChanges.我在ios模拟器中测试这个.我不知道如何检查设备.

如何删除mapkit上的所有叠加层？

我在ios应用程序中使用drawpdf函数生成pdf,同时在nsobject类中调用drawtext函数,它根据我指定的框架和字符串清楚地绘制文本.

我的代码是

+(void)drawText:(NSString*)textToDraw inFrame:(CGRect)frameRect
{

    CFStringRef stringRef = (__bridge CFStringRef)textToDraw;
// Prepare the text using a Core Text Framesetter
    CFAttributedStringRef currentText = CFAttributedStringCreate(NULL, stringRef, NULL);
    CTFramesetterRef framesetter = CTFramesetterCreateWithAttributedString(currentText);


    CGMutablePathRef framePath = CGPathCreateMutable();
    CGPathAddRect(framePath, NULL, frameRect);

// Get the frame that will do the rendering.
    CFRange currentRange = CFRangeMake(0, 0);
    CTFrameRef frameRef = CTFramesetterCreateFrame(framesetter, currentRange, framePath, NULL);
    CGPathRelease(framePath);

// Get the graphics context.
    CGContextRef    currentContext = UIGraphicsGetCurrentContext();

// Put the text matrix into a known state. This ensures
// that …

我正在使用iOS 7解决状态栏问题

if(st.version == 7)
{
    CGRect screen = [[UIScreen mainScreen] bounds];
    CGRect frame = self.navigationController.view.frame;
    frame.origin.y = 20;
    frame.size.height = screen.size.height - 20;
    self.navigationController.view.frame = frame;
}

因为我正在使用导航控制器并使用导航控制器从一个推送到另一个[self.navigationController pushViewController:newone animated:YES];.它适用于所有视图控制器.但是,如果viewcontroller在xib中有mkmapview,则会出现ios 7的状态栏问题.

如果我删除mapview表单xib并推送到该视图控制器意味着,它就像是,

如果我通过下面的代码添加mapview,

mapView = [[MKMapView alloc] initWithFrame:CGRectMake(0, 100, 320, 100)];
[self.view addSubview:self.mapView];

看起来像,

怎么解决这个？

我正在使用以下代码使用 QLPreviewcontroller 在我的应用程序中显示一些文档，

let ql = QLPreviewController()
ql.dataSource = self
//ql.navigationItem.rightBarButtonItems = nil
ql.navigationItem.rightBarButtonItem = nil
presentViewController(ql, animated: true, completion: nil)

我不想要 QLPreviewcontroller 右上角的共享按钮。我试过设置rightBarButtonItem为零，但它不起作用。

我怎么能隐藏呢？

对于播放YouTube视频,我正在使用

-(void)playYoutubeVideo:(NSString *)youtubeUrl {
  NSString *videoId =  [self extractYoutubeIdFromLink:youtubeUrl];
  NSLog(@"video Id %@",videoId);
  [self playVideoWithId:videoId];
}

- (NSString *)extractYoutubeIdFromLink:(NSString *)link {
  NSString *regexString = @"((?<=(v|V)/)|(?<=be/)|(?<=(\\?|\\&)v=)|(?<=embed/))([\\w-]++)";
  NSRegularExpression *regExp = [NSRegularExpression regularExpressionWithPattern:regexString
                                                                        options:NSRegularExpressionCaseInsensitive
                                                                          error:nil];
  NSArray *array = [regExp matchesInString:link options:0 range:NSMakeRange(0,link.length)];
  if (array.count > 0) {
    NSTextCheckingResult *result = array.firstObject;
    return [link substringWithRange:result.range];
  }
  return nil;
}

- (void)playVideoWithId:(NSString *)videoId {
  NSString *youTubeVideoHTML = @"<html><head><style>body{margin:0px 0px 0px 0px;}</style></head> <body> <div id=\"player\"></div> <script> var tag = document.createElement('script'); tag.src = 'http://www.youtube.com/player_api'; var firstScriptTag = document.getElementsByTagName('script')[0]; …

我正在使用UNUserNotificationCenterios 10.对于测试,我从当前时间开始设置本地通知10秒.

这是我试过的,

- (void)viewDidLoad {
    [super viewDidLoad];
     UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
     [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)
                          completionHandler:^(BOOL granted, NSError * _Nullable error) {
                              if (!error) {
                                  NSLog(@"request succeeded!");
                                  [self set10Notifs];
                              }
                          }];    
}

-(void) set10Notifs

    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"10.0")) {
    #if XCODE_VERSION_GREATER_THAN_OR_EQUAL_TO_8
     NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSCalendarIdentifierGregorian];

    [calendar setTimeZone:[NSTimeZone localTimeZone]];        

    NSDateComponents *components = [calendar components:NSCalendarUnitTimeZone fromDate:[[NSDate date] dateByAddingTimeInterval:10]];

    UNMutableNotificationContent *objNotificationContent = [[UNMutableNotificationContent alloc] init];
    objNotificationContent.title = [NSString localizedUserNotificationStringForKey:@"Prayer!" arguments:nil];
    objNotificationContent.body = [NSString localizedUserNotificationStringForKey:@"Time now"
                                                                        arguments:nil]; …
