ios-UILabel居中随内容自适应，后面的控件跟在其后

如图绿蓝框所示，UILabel显示名字，Label框随名字长短而自适应，后面的性别图片跟在其后显示

分两部分：第一部分先布局

//名字

self.nameLab = [[UILabel alloc]initWithFrame:CGRectMake(0, 200, SCREEN_WIDTH, 20)];

self.nameLab.textColor = [UIColor whiteColor];

self.nameLab.font = [UIFont fontWithName:@"Helvetica-Blod" size:19];

self.nameLab.textAlignment = NSTextAlignmentCenter;

self.nameLab.backgroundColor = [UIColor clearColor];

[self.bgV addSubview:self.nameLab];

//性别

self.sexImageView = [[EGOImageView alloc]init];

[self.bgV addSubview:self.sexImageView];

第二部分解析得到数据后，根据内容自适应宽度，再重设性别图片的位置

self.nameLab.text =  self.memberNmStr;//名字

[self.nameLab sizeToFit];

CGSize size = [self.nameLab.text sizeWithFont:[UIFont systemFontOfSize:19] constrainedToSize:CGSizeMake(SCREEN_WIDTH, 20) lineBreakMode:NSLineBreakByWordWrapping];

CGRect r1 = self.nameLab.frame;

r1.size.width = size.width;

self.nameLab.frame = r1;

self.nameLab.center = CGPointMake(self.bgV.frame.size.width/2, 130+10);

[self.sexImageView setFrame:CGRectMake(self.nameLab.frame.size.width + self.nameLab.frame.size.width + 10, 130, 20, 20)];

CGRect r2 = self.sexImageView.frame;

r2.origin.x = self.nameLab.frame.origin.x + 10 + self.nameLab.frame.size.width;

self.sexImageView.frame = r2;
