iOS formatted String For Duration

- (NSString*)formattedStringForDuration:(NSTimeInterval)duration

{

    NSInteger minutes = floor(duration/60);

    NSInteger seconds = round(duration - minutes * 60);

    return [NSString stringWithFormat:@"%d:%02d", minutes, seconds];

}

- (NSString *)stringFromTimeInterval:(NSTimeInterval)interval {

    NSInteger ti = (NSInteger)interval;

    NSInteger seconds = ti % 60;

    NSInteger minutes = (ti / 60) % 60;

    NSInteger hours = (ti / 3600);

    return [NSString stringWithFormat:@"%02i:%02i:%02i", hours, minutes, seconds];

iOS Resize Image scaled To Width

// Function

- (UIImage*)imageWithImage: (UIImage*) sourceImage scaledToWidth: (float) i_width

{

    float oldWidth = sourceImage.size.width;

    float scaleFactor = i_width / oldWidth;

    

    float newHeight = sourceImage.size.height * scaleFactor;

    float newWidth = oldWidth * scaleFactor;

    

    UIGraphicsBeginImageContext(CGSizeMake(newWidth, newHeight));

    [sourceImage drawInRect:CGRectMake(0, 0, newWidth, newHeight)];

    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();

    UIGraphicsEndImageContext();

    return newImage;

}

Use : [self imageWithImage:image scaledToWidth:254];
