嗨，我想实现如上图所示的屏幕。数据以JSON字符串的形式来自服务器，我已经解析了数据。

代码如下：

         UILabel *lblTitle  = [self createDynamicLabel:@"Seroquel"
                                           contentFrame:CGRectMake(10, 5, 150, 20) 
                                                  color:[UIColor blackColor] 
                                                   font:[UIFont fontWithName:@"Arial-BoldMT" size:17]];
        [scrollview addSubview:lblTitle];
        [lblTitle release];

        UILabel *lblGeneric       = [self createDynamicLabel:@"Generic Name:"
                                             contentFrame:CGRectMake(10, lblTitle.frame.size.height+5, 130, 20) 
                                                    color:[UIColor blackColor] 
                                                     font:[UIFont fontWithName:@"Arial-BoldMT" size:17]];
        [scrollview addSubview:lblGeneric];
        [lblGeneric release];

        UILabel *lblGenericName   = [self createDynamicLabel:DrugInfo.GenName
                                                contentFrame:CGRectMake(lblGeneric.frame.size.width+5, 24, 150, 20) 
                                                       color:[UIColor blackColor] 
                                                        font:[UIFont fontWithName:@"Arial-BoldMT" size:17]];
        [scrollview addSubview:lblGenericName];
        [lblGenericName release];

        UILabel *lblManufacturer  = [self createDynamicLabel:@"Manufacturer:"
                                                contentFrame:CGRectMake(10, 44, 115, 20) 
                                                       color:[UIColor blackColor] 
                                                        font:[UIFont fontWithName:@"Arial-BoldMT" size:17]];
        [scrollview addSubview:lblManufacturer];
        [lblManufacturer release];

        UILabel *lblManufacturerName = [self createDynamicLabel:DrugInfo.Mtr
                                                   contentFrame:CGRectMake(115, 43, 150, 20) 
                                                          color:[UIColor blackColor] 
                                                           font:[UIFont fontWithName:@"Arial-BoldMT" size:17]];
        [scrollview addSubview:lblManufacturerName];
        [lblManufacturerName release];

        //[self createDynamicView:CGRectMake(10, 70, 153, 128)];


        UILabel *lblCommon          = [self createDynamicLabel:@"Common uses:"
                                           contentFrame:CGRectMake(10, 209, 110, 20) 
                                                  color:[UIColor blackColor] 
                                                   font:[UIFont fontWithName:@"Arial-BoldMT" size:17]];
        lblCommon.backgroundColor   = [UIColor whiteColor];

        [lblCommon sizeToFit];
        [scrollview addSubview:lblCommon];
        [lblCommon release];

        NSString *genericInfo       = [NSString stringWithFormat:@"                        %@",DrugInfo.ComUse];
        UILabel *lblCommonUse       = [self createDynamicLabel:genericInfo
                                             contentFrame:CGRectMake(10, 208, 310, 80) 
                                                    color:[UIColor blackColor] 
                                                     font:[UIFont fontWithName:@"Arial-BoldMT" size:17]];


        //[lblCommonUse sizeToFit];
        lblCommonUse.lineBreakMode  = UILineBreakModeWordWrap;
        lblCommonUse.numberOfLines  = 0;
        [scrollview addSubview:lblCommonUse];
        [lblCommonUse release];



        UILabel *lblBefore          = [self createDynamicLabel:@" Before Using:"
                                           contentFrame:CGRectMake(10, 294, 102, 20) 
                                                  color:[UIColor blackColor] 
                                                   font:[UIFont fontWithName:@"Arial-BoldMT" size:17]];
        [lblBefore sizeToFit];
        lblBefore.backgroundColor   = [UIColor whiteColor];
        [scrollview addSubview:lblBefore];
        [lblBefore release];

        genericInfo                 = [NSString stringWithFormat:@"                        %@",DrugInfo.BeforeUse];
        UILabel *lblBeforeUse       = [self createDynamicLabel:genericInfo
                                             contentFrame:CGRectMake(10, 290, 308, 120) 
                                                    color:[UIColor blackColor] 
                                                     font:[UIFont fontWithName:@"Arial-BoldMT" size:17]];
        lblBeforeUse.lineBreakMode  = UILineBreakModeWordWrap;
        lblBeforeUse.numberOfLines  = 0;
        [scrollview addSubview:lblBeforeUse];
        [lblBeforeUse release];


    }  
}
}   


-(UILabel *)createDynamicLabel:(NSString *)setTitle 
              contentFrame:(CGRect)labelFrame 
                     color:(UIColor *)labelColor 
                      font:(UIFont *)labelFont {

UILabel  *dynamicLabel = [[UILabel alloc] init];
dynamicLabel.frame     = labelFrame;
dynamicLabel.text      = setTitle;
dynamicLabel.textColor = labelColor;
dynamicLabel.font      = labelFont;
dynamicLabel.backgroundColor = [UIColor clearColor];
return dynamicLabel;
}

但是如果数据超过可以在屏幕上显示的数据，它就会剪切它并且我想显示所有数据。任何人都可以帮我这么做吗？

提前致谢。

首先，我可以看到你将UI控件添加到UIScrollView，如果是这种情况，你需要确保你正在设置UIScrollView的contentSize属性。 UIScrollView不知道内容有多大，所以你需要弄清楚它并告诉UIScrollView。

如果使用定位变量（即CGFloat top; CGFloat left;）为控件设置框架并在添加控件时更新它们，而不是将位置值硬编码到代码中，则可以非常轻松地实现这一点。像这样的东西

CGFloat top = 5;
CGFloat left = 10;   
UILabel *lblTitle  = [self createDynamicLabel:@"Seroquel"
                                       contentFrame:CGRectMake(left, top, 150, 20) 
                                              color:[UIColor blackColor] 
                                               font:[UIFont fontWithName:@"Arial-BoldMT" size:17]];
[scrollview addSubview:lblTitle];
[lblTitle release];

top += lblTitle.frame.size.height;

UILabel *lblGeneric       = [self createDynamicLabel:@"Generic Name:"
                                         contentFrame:CGRectMake(left, top, 130, 20) 
                                                color:[UIColor blackColor] 
                                                 font:[UIFont fontWithName:@"Arial-BoldMT" size:17]];
[scrollview addSubview:lblGeneric];
[lblGeneric release];

left += lblGeneric.frame.size.width;

UILabel *lblGenericName   = [self createDynamicLabel:DrugInfo.GenName
                                            contentFrame:CGRectMake(left, top, 150, 20) 
                                                   color:[UIColor blackColor] 
                                                    font:[UIFont fontWithName:@"Arial-BoldMT" size:17]];
[scrollview addSubview:lblGenericName];
[lblGenericName release];

然后，最后，您可以使用top制作CGSize来设置contentSize。

我还建议您查看使用UITableView或使用NSAttributedString，因为它们可能会帮助您以其他方式实现您想要的效果。
