我想从日期选择器获取最小和最大日期,但最小日期应为当前日期的" - 18",最大日期应为当前日期的" - 100".
假设当前年份是2018年,那么我想要最小日期2000和最大日期1918.
到目前为止我所做的是:
NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];
NSDateComponents *components = [gregorian components:NSYearCalendarUnit fromDate:[NSDate date]];
NSInteger year = [components year];
int mindt = year - 18;
int maxdt = year -100;
// NSDate * MinDate = [components year] - 18;
// NSDate * MaxDate = [components year] - 100;
// self.datePicker.minimumDate = MinDate;
// self.datePicker.maximumDate = MaxDate;
但我不能得到这个整数到我的日期格式..
我用我的屏幕(桌面)捕获软件创建了.mov视频文件,我想在UIWebview中的应用程序中播放该视频.有没有办法播放该视频或任何其他方式,以便我可以为我的本地视频创建一个URL ???
现在我使用默认视频链接在UIWebview中播放视频.
这是代码:
- (void)applicationDidBecomeActive:(UIApplication *)application
{
self.viewVideoDisplay.frame = CGRectMake(0, 0, 1024, 1024);
[self.window addSubview:self.viewVideoDisplay];
[self.window bringSubviewToFront:self.viewVideoDisplay];
NSString *urlAddress = @"https://response.questback.com/pricewaterhousecoopersas/zit1rutygm/";
//Create a URL object.
NSURL *url = [NSURL URLWithString:urlAddress];
//URL Requst Object
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
//Load the request in the UIWebView.
[self.webViewVideo loadRequest:requestObj];
IsLoadingSelf = YES;
}
但是我没有想要播放的视频网址..
请帮助!!
我有一个35项的NSMutableArray,我想将前10个项目复制到另一个数组.
在我的数组中添加10个项目后,我想再次添加相同的10个项目.
请建议我怎么做.
代码:
我用这种方式初始化了包含所有图像的数组
self.arrayAllAnimalImages = [[NSMutableArray alloc] init];
[self.arrayAllAnimalImages addObject:@"bagheera.jpg"];
[self.arrayAllAnimalImages addObject:@"baloo.jpg"];
[self.arrayAllAnimalImages addObject:@"bear.jpg"];
[self.arrayAllAnimalImages addObject:@"bird.jpg"];
[self.arrayAllAnimalImages addObject:@"camel.jpg"];
[self.arrayAllAnimalImages addObject:@"cock.jpg"];
[self.arrayAllAnimalImages addObject:@"deer.jpg"];
[self.arrayAllAnimalImages addObject:@"dolphin.jpg"];
[self.arrayAllAnimalImages addObject:@"donkey.jpg"];
[self.arrayAllAnimalImages addObject:@"elephant.jpg"];
[self.arrayAllAnimalImages addObject:@"fish.jpg"];
[self.arrayAllAnimalImages addObject:@"flamigo.jpg"];
[self.arrayAllAnimalImages addObject:@"frog.jpg"];
[self.arrayAllAnimalImages addObject:@"girraf.jpg"];
[self.arrayAllAnimalImages addObject:@"hippo.jpg"];
[self.arrayAllAnimalImages addObject:@"monkey.jpg"];
[self.arrayAllAnimalImages addObject:@"octopus.jpg"];
[self.arrayAllAnimalImages addObject:@"owl.jpg"];
[self.arrayAllAnimalImages addObject:@"panda.jpg"];
[self.arrayAllAnimalImages addObject:@"parrot.jpg"];
[self.arrayAllAnimalImages addObject:@"peacock.jpg"];
[self.arrayAllAnimalImages addObject:@"penguin.jpg"];
[self.arrayAllAnimalImages addObject:@"piglet.jpg"];
[self.arrayAllAnimalImages addObject:@"polarbear.jpg"];
[self.arrayAllAnimalImages addObject:@"pumba.jpg"];
[self.arrayAllAnimalImages addObject:@"rabbit.jpg"];
[self.arrayAllAnimalImages addObject:@"redpanda.jpg"];
[self.arrayAllAnimalImages addObject:@"seahorse.jpg"];
[self.arrayAllAnimalImages addObject:@"simba.jpg"];
[self.arrayAllAnimalImages addObject:@"snake.jpg"];
[self.arrayAllAnimalImages addObject:@"starfish.jpg"];
[self.arrayAllAnimalImages addObject:@"tiger.jpg"];
[self.arrayAllAnimalImages addObject:@"tigger.jpg"];
[self.arrayAllAnimalImages addObject:@"turtle.jpg"];
[self.arrayAllAnimalImages addObject:@"whale.jpg"]; …我正在将图像分配给我的nsdata对象,Coredata并在分配之后我正在检查是否NSData有图像.
如果数据不为null,我必须显示它.另外我在NSLog中录制"没有找到图像".
仅当对象中没有图像时,应用程序才会崩溃.
我试过了:
NSData * dataImage;
if (dataImage == nil)
{
NSLog(@"Image is Assigned .... " );
}
else
{
NSLog(@"Image is Not Assigned ITS NIL.... " );
}
我的设备控制台如下所示:
