だから私はそれを別のウィンドウ/ビューコントローラーに渡した後、UIlabelテキストの高さを計算するのに問題があります
渡すための私のコードはこちら
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NetraDealsObject *dataObject=[self.deals_data_json objectAtIndex:indexPath.row];
detailViewController = [[MJDetailViewController alloc] initWithNibName:@"MJDetailViewController" bundle:nil];
[self presentPopupViewController:detailViewController animationType:MJPopupViewAnimationSlideBottomBottom];
detailViewController.NetraPopupPrice.text=dataObject.formatted;
}
たとえば、text==123;
ここではdetailviewController
-(id) initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self=[super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if(self){
NetraPopupPrice=[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
NetraPopupPrice.backgroundColor=[UIColor colorWithRed:0.31 green:0.733 blue:0 alpha:1]; /*#4fbb00*/
NetraPopupPrice.textColor=[UIColor whiteColor];
NetraPopupPrice.textAlignment=NSTextAlignmentCenter;
NetraPopupPrice.font=[UIFont fontWithName:@"HelveticaNeue-Bold" size:18];
[NetraPopupPrice.layer setCornerRadius:3];
NetraPopupProvider=[[UILabel alloc] initWithFrame:CGRectMake(135.0f, 55, 80, 16)];
NetraPopupProvider.backgroundColor=[UIColor clearColor];
NetraPopupProvider.textColor=[UIColor colorWithRed:0.769 green:0.776 blue:0.788 alpha:1];
NetraPopupProvider.font=[UIFont fontWithName:@"Helvetica" size:13];
//separator
NetraPopupSeparator=[[UILabel alloc] initWithFrame:CGRectMake(215,55.0f, 80, 16)];
NetraPopupSeparator.text=@"-",
NetraPopupSeparator.backgroundColor=[UIColor clearColor];
NetraPopupSeparator.textColor=[UIColor colorWithRed:0.769 green:0.776 blue:0.788 alpha:1];
NetraPopupSeparator.font=[UIFont fontWithName:@"Helvetica" size:13];
//
//separator
NetraPopupLocation=[[UILabel alloc] initWithFrame:CGRectMake(225, 55.0f, 70, 16)];
NetraPopupLocation.backgroundColor=[UIColor clearColor];
NetraPopupLocation.textColor=[UIColor colorWithRed:0.769 green:0.776 blue:0.788 alpha:1];
NetraPopupLocation.font=[UIFont fontWithName:@"Helvetica" size:13];
NetraPopupHeadline=[[UILabel alloc] init];
NetraPopupHeadline.textColor=[UIColor colorWithRed:0.227 green:0.243 blue:0.247 alpha:1];
NetraPopupHeadline.lineBreakMode=NSLineBreakByCharWrapping;
NetraPopupHeadline.backgroundColor=[UIColor redColor];
NetraPopupHeadline.numberOfLines=0;
NetraPopupHeadline.font=[UIFont fontWithName:@"HelveticaNeue-Bold" size:13];
}
[[self view] addSubview:NetraPopupPrice];
[[self view] addSubview:NetraPopupProvider];
[[self view] addSubview:NetraPopupSeparator];
[[self view] addSubview:NetraPopupLocation];
[[self view] addSubview:NetraPopupHeadline];
return self;
}
-(void)viewDidLoad{
[super viewDidLoad];
CGSize NetraLabelForPriceWidth = [[NetraPopupPrice text] sizeWithFont:[NetraPopupPrice font]];
CGFloat NetraLabelForPriceW = NetraLabelForPriceWidth.width;
NSLog(@"Width=%f",NetraLabelForPriceW);
}
-(void)viewWillAppear:(BOOL)animated{
}
- (void)viewDidUnload {
[super viewDidUnload];
}
@end
そしてそれをログに記録したときの結果
NSLog(@"Width=%f",NetraLabelForPriceW);
は:
[9858:19d03] Width=0.000000
それは正しく計算する必要がありますか?私のコードに何か問題がありますか?
