IOS

在图形绘制中,我们经常会需要绘制文本,但我在给PDF上绘制Text时,始终绘制不上,

使用过:

[str drawInRect:cubeRect withAttributes:attrs];

CGContextShowTextAtPoint(ctx, 100.0, 100.0, "SOME TEXT", 9);

。。。。。等等,

结果,都不能显示,令我郁闷了一段时间。。。

最总找到了问题所在:

UIGraphicsPushContext(ctx);

[word drawAtPoint:CGPointMake(30.0f, 30.0f)
forWidth:200.0f
withFont:[UIFont boldSystemFontOfSize:32]
lineBreakMode:UILineBreakModeClip];

UIGraphicsPopContext();
