这里是我的代码

-(void)TextHeight 
{ 

    NSString *message = txtmain.text; 
    CGSize size = [message sizeWithFont:[UIFont fontWithName:fontName size:fontsize] constrainedToSize:CGSizeMake(lblTextInBubbles.frame.size.width, 9999.0f) lineBreakMode:NSLineBreakByCharWrapping]; 


    CGFloat height = size.height+60; 
    CGFloat width = size.width+50; 

    // NSLog(@"w== %f,, H==%f",width,height); 

    if(lblpositionwidth < 210) 
    { 
     if(lblPositionDynamicChange > 33) 
     { 
      lblPositionDynamicChange=lblPositionDynamicChange-3; 

     } 

     lblTextInBubbles.frame=CGRectMake(lblPositionDynamicChange, lblTextInBubbles.frame.origin.y, width, height); 

     lblpositionwidth=lblTextInBubbles.frame.size.width; 
    }else 
    { 
     if(lblTextInBubbles.frame.size.height < 125) 
     { 
      if(lblPositionDynamicChangeY > 38) 
      { 
       lblPositionDynamicChangeY=lblPositionDynamicChangeY-10; 

      } 
      lblTextInBubbles.frame=CGRectMake(lblTextInBubbles.frame.origin.x, lblPositionDynamicChangeY, lblTextInBubbles.frame.size.width, height); 
     }else 
     { 
      NSLog(@"%lu",(unsigned long)[lblTextInBubbles.text length]); 

     } 
    } 
    lblTextInBubbles.lineBreakMode=6; 
    // NSLog(@"After= %f",lblTextInBubbles.frame.origin.x); 
    [self setBubblesImageFrame]; 
} 
-(void)setBubblesImageFrame 
{ 
    imgbabble.frame = CGRectMake(lblTextInBubbles.frame.origin.x -55, lblTextInBubbles.frame.origin.y-55, lblTextInBubbles.frame.size.width+100, lblTextInBubbles.frame.size.height+100); 
} 

- (IBAction)txt_editing:(id)sender 
{ 
    [self TextHeight]; 
    lblTextInBubbles.textAlignment = NSTextAlignmentCenter; 
    /* if([txtmain.text length] > 16) 
    { 
     NSLog(@"x=%f,y=%f,,,,, width=%f,,,,height=%fds",imgbabble.frame.origin.x,imgbabble.frame.origin.y,imgbabble.frame.size.width,imgbabble.frame.size.height); 

     imgbabble.frame=CGRectMake(imgbabble.frame.origin.x-10, imgbabble.frame.origin.y-5, 160, 64); 
     // NSLog(@"x=%f,y=%f,,,,, width=%f,,,,height=%fds",imgbabble.frame.origin.x,imgbabble.frame.origin.y,imgbabble.frame.size.width,imgbabble.frame.size.height); 
    }*/ 
    lblTextInBubbles.text=txtmain.text; 
    lblTextInBubbles.textColor= [UIColor whiteColor]; 

    lblTextInBubbles.layer.borderColor=[UIColor whiteColor].CGColor; 
     lblTextInBubbles.layer.borderWidth=1.0; 

}

我建议你使用可拉伸的图像，并为每一个定义适当的边缘插入。您可以轻松地将包裹你身边文本RECT：

UIImage *bubbleImage = [[UIImage imageWithCGImage:[UIImage imageNamed:@"ImageBubble~iphone"].CGImage scale:1.0 orientation:UIImageOrientationRight] resizableImageWithCapInsets:UIEdgeInsetsMake(13, 13, 13, 21) resizingMode:UIImageResizingModeStretch]; 

UIImageView *bubbleImageView = [[UIImageView alloc] initWithImage:bubbleImage]; 
bubbleImageView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; 
bubbleImageView.frame = ...;
