小编Rah*_*hul的帖子

  - (void)drawRect:(CGRect)rect {
    CGContextRef  context = UIGraphicsGetCurrentContext();


    CGContextSelectFont(context, "Arial", 24, kCGEncodingMacRoman);


    CGContextShowTextAtPoint(context, 80, 80, "I am Rahul", 7);





 }

我正在尝试绘制文本,如上所示"我是Rahul",但是当我执行代码时,
文本显示,但它被反转,为什么它发生我不会得到!! 救命!!

#import <UIKit/UIKit.h>

@interface quartzViewController : UIViewController {
 IBOutlet UIView *myView;

}

@end


#import "quartzViewController.h"

@implementation quartzViewController


   -(void)drawRect:(CGRect)rect
   {   

 CGContextRef  context = UIGraphicsGetCurrentContext();
 CGContextSelectFont(context, "Arial", 24, kCGEncodingFontSpecific);
 CGContextSetTextPosition(context,80,80);
 CGContextShowText(context, "hello", 6);
 //not even this works
 CGContextShowTextAtPoint(context, 1,1, "hello", 6);
   }

   - (void)viewDidLoad {
 [myView setNeedsDisplay];

 [super viewDidLoad];
   }

我是否必须在笔尖中进行任何更改？

谢谢
