UILabel *indexLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, self.view.frame.size.height-150, self.view.frame.size.width/2,30)]; 
      [indexLabel setBackgroundColor:[UIColor clearColor]]; 
      indexLabel.textColor = [UIColor whiteColor]; 
      indexLabel.text = @"Details:-"; 
      indexLabel.font = [UIFont systemFontOfSize:20.00]; 
      UILabel *tagLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, self.view.frame.size.height-120, self.view.frame.size.width/2, 30)]; 
      tagLabel.backgroundColor = [UIColor clearColor]; 


      NSLog(@"LOg %@",imageId); 
      NSLog(@"LOg %@",imageStyle); 
      NSLog(@"LOg %@",imageType); 
      NSLog(@"LOg %@",imageWeight); 
      tagLabel.text = [NSString stringWithFormat:@"The Id of Jewl Is: %@",imageId]; 

      imageTypelabel= [[UILabel alloc] initWithFrame:CGRectMake(20, self.view.frame.size.height-90, self.view.frame.size.width/2, 30)]; 
      imageTypelabel.backgroundColor = [UIColor clearColor]; 
      imageTypelabel.text = [NSString stringWithFormat:@"The Type of Jewl Is: %@",imageType]; 
      imageStylelabel = [[UILabel alloc] initWithFrame:CGRectMake(20, self.view.frame.size.height-60, self.view.frame.size.width/2, 30)]; 
      imageTypelabel.backgroundColor = [UIColor clearColor]; 
      imageStylelabel.text = [NSString stringWithFormat:@"The style of Jewl Is: %@",imageStyle]; 
      imageWeightlabel = [[UILabel alloc] initWithFrame:CGRectMake(20, self.view.frame.size.height-30, self.view.frame.size.width/2, 30)]; 
      imageStylelabel.backgroundColor = [UIColor clearColor]; 
      imageWeightlabel.text = [NSString stringWithFormat:@"The weight of Jewl Is: %@",imageWeight]; 
      imageWeightlabel.backgroundColor = [UIColor clearColor]; 
      imageWeightlabel.textColor = [UIColor whiteColor]; 
      imageTypelabel.textColor = [UIColor whiteColor]; 
      imageWeightlabel.textColor = [UIColor whiteColor]; 
      tagLabel.textColor = [UIColor whiteColor]; 
      UIImage *imageBegin = [UIImage imageNamed:imageName]; 
      UIImageView *imageView = [[UIImageView alloc] initWithImage:imageBegin]; 


      UIView *cellSeparator = [[UIView alloc] initWithFrame:CGRectMake(0,545, self.view.frame.size.width ,3)]; 
      cellSeparator.tag=1; 
      [cellSeparator setAutoresizingMask:UIViewAutoresizingFlexibleLeftMargin | 
      UIViewAutoresizingFlexibleRightMargin | 
      UIViewAutoresizingFlexibleWidth];  
      [cellSeparator setContentMode:UIViewContentModeTopLeft];  
      [cellSeparator setBackgroundColor:[UIColor whiteColor]]; 
      [self.view addSubview:cellSeparator];

当你第二次打电话时删除超视图的子视图吗？ – Balu

1.不是Xcode的问题，2.该类被称为'UIView'，而不是'UIVIEW'。 – 2013-04-01 11:07:15

要将哪个视图添加该标签和imageView –

你可以写一个方法来清除所有视图的子视图并根据您的需要修改此代码。

- (void)removeSubviewsOfView 
{ 
    NSArray *subViews = [self.view subviews]; 
    for(UIView *view in subViews) 
    { 
     [view removeFromSuperview]; 
    } 
}
