如何在UITextView中繪制文本

Question

就像在UILabel和UITextField中有一個稱為“ drawTextInRect：”的方法一樣，如何在UITextView中繪制文本。 我應該在“ drawRect：”或“ drawLayer：inContext：”中實現它。 感謝您的關注和耐心！

Answer 1

您可以像以下代碼一樣使用drawinrect。

UIFont *font = [UIFont fontWithName:@"Courier" size:kCellFontSize];

/// Make a copy of the default paragraph style
NSMutableParagraphStyle *paragraphStyle = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
/// Set line break mode
paragraphStyle.lineBreakMode = NSLineBreakByTruncatingTail;
/// Set text alignment
paragraphStyle.alignment = NSTextAlignmentRight;

NSDictionary *attributes = @{ NSFontAttributeName: font,
                    NSParagraphStyleAttributeName: paragraphStyle };

[text drawInRect:rect withAttributes:attributes];
