我有一个应用程序,其中有一个带有图像的选择器视图。我已经这样做了。
picker1=[[UIPickerView alloc] init];
picker1.frame= CGRectMake(30,90,155,316);
picker1.delegate = self;
picker1.dataSource = self;
picker1.showsSelectionIndicator = YES;
picker1.tag = 1;
[self.view addsubview:picker1];
我正在使用 viewForRow 委托方法来加载图像。我需要在 pickerview 中增加图像框架。`
UIImage *img = [UIImage imageNamed:[NSString stringWithFormat:@"%@.png",[self.array objectAtIndex:row]]];
UIImageView *icon = [[UIImageView alloc] initWithImage:img];
//temp.frame = CGRectMake(170, 0, 30, 30);
UIView *tmpView = [[[UIView alloc] initWithFrame:CGRectMake(155,75,95,35)] autorelease];
[tmpView insertSubview:icon atIndex:0];
picker1.backgroundColor = [UIColor clearColor];
[(UIView*)[[picker1 subviews] objectAtIndex:2] setAlpha:0.0f];
[(UIView*)[[picker1 subviews] objectAtIndex:0] setAlpha:0.0f];
[(UIView*)[[picker1 subviews] objectAtIndex:1] setAlpha:0.0f];
[(UIView*)[[picker1 subviews] objectAtIndex:3] setAlpha:0.0f];
[tmpView setUserInteractionEnabled:NO];
[tmpView setBackgroundColor:[UIColor clearColor]];
[tmpView setTag:row];
return tmpView;
但是当我尝试增加视图的框架时,它的位置只会改变,而不是大小。有人可以帮我实现这一点吗?
