Question

我的代码是

UILabel *pTeamAlreadybl=[[UILabel alloc]initWithFrame:CGRectMake(110, 275,180,30)];

pTeamAlreadybl.text=@" Team already?";
pTeamAlreadybl.font=[UIFont boldSystemFontOfSize:16];
pTeamAlreadybl.textAlignment=UITextAlignmentLeft;
pTeamAlreadybl.textColor=[UIColor colorWithRed:61.0/255.0 green:61.0/255.0 blue:61.0/255.0 alpha:0.6];
pTeamAlreadybl.shadowColor = [UIColor colorWithWhite:1.0 alpha:0.7];

如何更改标签的背景颜色？

Answer 1

你错过了

pTeamAlreadybl.backgroundColor=[UIColor anycolor];

编写此代码

Answer 2

要更改 UILabel 的背景颜色，您需要设置UILabel对象的 backgroundColor 属性。您可以使用以下代码行来执行此操作：

[pTeamAlreadybl setBackgroundColor:[UIColor colorOfYourChoice]];

OR

pTeamAlreadybl.backgroundColor = [UIColor colorOfYourChoice];

Answer 3

pTeamAlreadybl.backgroundColor = [UIColor ...];

上述代码不起作用吗？

Answer 4

[pTeamAlreadybl setBackgroundColor:[UIColor YourColor]];

YourColor如下所述

blackColor;
darkGrayColor; lightGrayColor whiteColor;
grayColor;
redColor;
绿彩;
blueColor;
cyanColor;
黄色颜色;
magentaColor; orangeColor;
purpleColor;
brownColor;
clearColor;

你也可以像这样使用自定义颜色

[UIColor colorWithRed:61.0/255.0 green:61.0/255.0 blue:61.0/255.0 alpha:0.6]
