我的想法是填充图片数组和描述以填充UIPickerView
My idea is to fill an array of pictures and a description to fill the UIPickerView
推荐答案
请尝试将数据获取为数组
NSDictionary
。
Try to get your data as Array
of NSDictionary
.
字典结构: {图片:< imageName>,LabelText:< labelText>}
- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row
forComponent:(NSInteger)component reusingView:(UIView *)view
{
NSDictionary *dict = [datasourceArray objectAtIndex:row];
UIImage *img = [UIImage imageNamed:[dict valueForKey:@"Image"]]; // get image path from the dictionary
UIImageView *temp = [[UIImageView alloc] initWithImage:img];
temp.frame = CGRectMake(-70, 10, 60, 40);
UILabel *channelLabel = [[UILabel alloc] initWithFrame:CGRectMake(50, -5, 80, 60)];
channelLabel.text = [dict valueForKey:@"LabelText"];
channelLabel.textAlignment = UITextAlignmentLeft;
channelLabel.backgroundColor = [UIColor clearColor];
UIView *tmpView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 110, 60)];
[tmpView insertSubview:temp atIndex:0];
[tmpView insertSubview:channelLabel atIndex:1];
return tmpView;
}
