Autoplay media files in UIWebView in IOS

When displaying media content using HTML5 in a web view on IOS the autoplay functionality does not work.

To enable to web view to autoplay the media (if coded in HTML to autoplay) you need to add a line of code in your IOS application as explained.

Let's say you have a webview object declared as in line below.

UIWebView *videoView;

Then you need to add the code after initializing the webview as below.

videoView.mediaPlaybackRequiresUserAction = NO;
videoView.allowsInlineMediaPlayback = YES

This forces the video/audio to autoplay in UIWebView if directed in HTML code.

How to get sub strings from a string using Regular Expression

Hi, The below code is to get sub-strings from a string. You are going to love this below code which is very simple but very effective. I have used regular expression to get the sub strings.

NSString *strTest = @"Hii how are you doing @Ravi , how do u do @Kiran  where are you @Varun";
NSError *error;  
NSRegularExpression *exp =[NSRegularExpression regularExpressionWithPattern:@"@[^ ]*" options:NSRegularExpressionCaseInsensitive error:&error];
NSArray *s1= [exp matchesInString:strTest options:NSMatchingReportCompletion range:NSMakeRange(0, [strTest length]) ];
    [s1 enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
        NSTextCheckingResult *result = obj;
        NSString *str = [strTest substringWithRange:result.range];
        NSLog(@"str %@",str);

    }];

Save the other Object in array using For loop

To add the object in array in for Loop we have several methods: first we can have to simply add those objects to the array then we can add them using for loop in array..... **IN example:** we have a simple object *object that we added 3 times at diffrent index postion in array(**mutArray)..** And other method is to add the object from another array: for that we accessed the each object at current index from the array and added that to the another array(**myMutableArray**)...

NSMutableArray *mutArray=[[NSMutableArray alloc]init];

    for(int i=0;i<=2;i++)
    {
        NSString *object=@"Hello";
        [mutArray addObject:object];
    }
     NSLog(@"Mutable Array==%@",mutArray);


    //if the object are in other array then

    NSArray *objArray=[[NSArray alloc]initWithObjects:@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"10",nil];
    NSLog(@"obje==%@",objArray);
    NSMutableArray *myMutableArray=[[NSMutableArray alloc]init];;

    for(int index=0;index<objArray.count;index++)
    {

        [myMutableArray addObject:[objArray objectAtIndex:index]];


    }
    NSLog(@"myMutable Array==%@",myMutableArray);
