ios UITextVIew通过text的内容，来计算UITextView的heigh，因此来调整代码的位置，

下面代码，是提取出来的公用方法，可以参考：

- (void)setScrollViewFrame{

    CGSize  size = [self.txtViewContent.textsizeWithFont:[UIFontsystemFontOfSize:14]constrainedToSize:CGSizeMake(300,1000) lineBreakMode:UILineBreakModeWordWrap];  

    [txtViewContent setFrame:CGRectMake(self.txtViewContent.frame.origin.x,self.txtViewContent.frame.origin.y, size.width, size.height+43)];

    [lblRelativeNews setFrame:CGRectMake(self.lblRelativeNews.frame.origin.x,lbl_y+self.txtViewContent.frame.size.height-0,self.lblRelativeNews.frame.size.width,self.lblRelativeNews.frame.size.height)];

    [newsRelatedBtn1 setFrame:CGRectMake(self.newsRelatedBtn1.frame.origin.x,btnFirst_y+self.txtViewContent.frame.size.height-0,self.newsRelatedBtn1.frame.size.width,self.newsRelatedBtn1.frame.size.height)];

    [newsRelatedBtn2 setFrame:CGRectMake(self.newsRelatedBtn2.frame.origin.x,btnFirst_y+self.txtViewContent.frame.size.height-0,self.newsRelatedBtn2.frame.size.width,self.newsRelatedBtn2.frame.size.height)];

    [newsRelatedBtn3 setFrame:CGRectMake(self.newsRelatedBtn3.frame.origin.x,btnFirst_y+self.txtViewContent.frame.size.height-0,self.newsRelatedBtn3.frame.size.width,self.newsRelatedBtn3.frame.size.height)];

    MainScrollView.backgroundColor = [UIColorclearColor];

    MainScrollView.contentSize =CGSizeMake(DEVICE_WIDTH,MainScrollView.frame.size.height+self.txtViewContent.frame.size.height+10);

    NSLog(@"MainScrollView.contentOffset.x:%f",MainScrollView.contentOffset.x);

    NSLog(@"MainScrollView.contentOffset.y:%f",MainScrollView.contentOffset.y); 

    [MainScrollViewsetContentOffset:CGPointMake(0,0) animated:NO];

}
