drawInRect deprecated in ios7

[ilant]

[hautelook-jimmy]

Here is my fix, not tested because we don't use pageNumber.

            NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle defaultParagraphStyle] mutableCopy];
            paragraphStyle.lineBreakMode = NSLineBreakByWordWrapping;
            paragraphStyle.alignment = NSTextAlignmentCenter;
            [pageNumber drawInRect:CGRectMake(x,(self.frame.size.height-_currentPageDiameter)/2-1,_currentPageDiameter,_currentPageDiameter) withAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:_currentPageDiameter-2], NSParagraphStyleAttributeName:paragraphStyle}];
