Objective-c：以编程方式设计UIView / UILabel

Question

我想在目标c 中以编程方式设计UIView / UILabel这样的图像。特别是中间的边缘。有人可以帮忙吗？

目前我有：

UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(self.tabPosition.x,self.tabPosition.y,120,20)]; //or whatever size you need
            myLabel.center = self.tabPosition;
            [myLabel setFont:[UIFont systemFontOfSize:12]];
            myLabel.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.6f];
            myLabel.textColor = [UIColor whiteColor];
            myLabel.textAlignment = NSTextAlignmentCenter;
            myLabel.text = [NSString stringWithFormat:@"%@  %@",data.user.firstName,data.user.lastName] ;
            myLabel.tag = indexPath.row;
            myLabel.userInteractionEnabled = YES;

            UIPanGestureRecognizer *gesture = [[UIPanGestureRecognizer alloc]
                                               initWithTarget:self
                                               action:@selector(labelDragged:)] ;
            [myLabel addGestureRecognizer:gesture];


            [self.picture addSubview:myLabel];

哪位给我：

Answer 1

你需要一个像你一样的小图像。

设置UIImageview的拉伸属性，使其按您设置文本大小和边缘将保持在中间（refer this link）
