둥근 버튼에 배지 아이콘을 추가 하시겠습니까?

Question

배지가있는 버튼을 만드는 편리한 방법이 있습니까? 아이콘에 없으면 ... 앱 안에서 해보고 싶습니다. 프로그램에서 선택한 배지가있는 단추 또는 이미지. 아니면 포토샵 이미지 라이브러리를 만들어야합니까?

Answer 1

포토샵 이미지 라이브러리없이이 작업을 수행하려면 resizableImageWithCapInsets을 사용해야합니다. 그 사용법을 설명하는 위대한 스레드 (here 및 here)가 있습니다.

//Create a label (width/height not important at this stage) 
UILabel *yourLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 1, 1)]; 
yourLabel.text = @"7+"; 
[yourLabel sizeToFit]; 

CGRect labelFrame = yourLabel.frame; 

//Here we create a UIImage that is resizable, but will not resize the areas concerned with the cap insets you've defined 
UIImage *badgeImage = [[UIImage imageNamed:@"badge.png"]resizableImageWithCapInsets:UIEdgeInsetsMake(5, 5, 5, 5)]; 
UIImageView *badgeImageView = [[UIImageView alloc]initWithImage:badgeImage]; 

badgeImageView.contentMode = UIViewContentModeScaleToFill; 
badgeImageView.backgroundColor = [UIColor clearColor]; 

labelFrame.size.width += 5; //This is the 'padding' on the right and left (added together) 
//If your badge edges are completely circular then you don't want to change the height, but if they're not then go ahead in the same way with the width. If your badge has a static height, you'll need to make sure the font size doesn't exceed this height; better start off with a small font-size 

badgeImageView.frame = labelFrame; //The badge is now the right width with padding taken into account 

//Center the label on the badge image view 
yourLabel.center = CGPointMake(badgeImageView.frame.size.width/2, badgeImageView.frame.size.height/2); 

//Finally we add the label to the badge image view 
[badgeImageView addSubview:yourLabel]; 
//Add your badge to the main view 
[self.view addSubview:badgeImageView]; 

[badgeImageView release]; 
[yourLabel release];

UILabel *lbl_notification_count = [[UILabel alloc]initWithFrame:CGRectMake(5,0, 18, 18)]; 

     lbl_notification_count.textColor = [UIColor whiteColor]; 

     lbl_notification_count.textAlignment = NSTextAlignmentCenter; 

     lbl_notification_count.text = [NSString stringWithFormat:@"%d",appDel.NotificationBadge]; 

     lbl_notification_count.adjustsFontSizeToFitWidth=YES; 

     lbl_notification_count.layer.borderWidth = 1; 

     lbl_notification_count.layer.cornerRadius = lbl_notification_count.layer.frame.size.height/2; 

     lbl_notification_count.layer.masksToBounds = YES; 

     lbl_notification_count.layer.borderColor =[[UIColor colorWithRed:241.0/255.0 green:84.0/255.0 blue:67.0/255.0 alpha:1.0] CGColor]; 

     lbl_notification_count.backgroundColor = [UIColor colorWithRed:241.0/255.0 green:84.0/255.0 blue:67.0/255.0 alpha:1.0]; 

     lbl_notification_count.font = CustomFontMediumWithSize(12); 

     if (appDel.NotificationBadge >= 1) { 

      [btnNotification addSubview:lbl_notification_count]; 

      [lbl_notification_count setHidden:NO]; 

     }else{ 

      [lbl_notification_count setHidden:YES]; 

     }
