IOS UILabel

UILabel自适应

    UILabel* labelJinE = [[UILabel alloc]init];
    labelJinE.text = @"到账金额：--元";
    labelJinE.font = [UIFont systemFontOfSize:16];
    [labelJinE sizeToFit];
    labelJinE.center = CGPointMake((WINDOW_WIDTH-ButtonWide*3)/4*1+labelJinE.bounds.size.width/2, 72/2);
    [viewButtom addSubview:labelJinE];

其中[labelJinE sizeToFit] 要写在center之前，否则先设置了center，后在自适应frame，会有些偏差，如果要加上确定的frame，代码如下

    UILabel* labelJinE = [[UILabel alloc]init];
    labelJinE.text = @"到账金额：--元";
    labelJinE.font = [UIFont systemFontOfSize:16];
     labelJinE.bounds = CGRectMake(0, 0, 96, 44);
    labelJinE.center = CGPointMake((WINDOW_WIDTH-ButtonWide*3)/4*1+labelJinE.bounds.size.width/2, 72/2);
    [viewButtom addSubview:labelJinE];

其中设置buounes需要在center之前，不需要添加sizeToFit，前提确保你的bounds 是对的
