如何在iPhone中设置特定按钮的背景颜色？

我用了:

btnName1 = [ColorfulButton buttonWithType:UIButtonTypeRoundedRect];
btnName1.frame=CGRectMake(45,146,220,40);
[btnName1 setTitle:@"Continue" forState:UIControlStateNormal]; 
[btnName1 setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; 
[btnName1 setImage:[UIImage imageNamed:@"green.png"] forState:UIControlStateNormal];
UIImage *img =[UIImage imageWithContentsOfFile:[[NSBundle mainBundle]pathForResource:@"greenish" ofType:@"png"]];
UIImage *strechableImage = [img stretchableImageWithLeftCapWidth:12 topCapHeight:0];
[btnName1 setBackgroundImage:strechableImage forState:UIControlStateNormal];
[btnName1 setNeedsDisplay];
[InfoView addSubview:btnName1];

它在iPhone模拟器上正常工作,但在iPod上没有(iPod中没有显示颜色).

Answer 1

myButton.backgroundColor = [UIColor redColor];

或者你想要的任何颜色.此方法继承自UIView.

请注意,这仅设置背景颜色......

如果你想改变按钮的外观:

[myButton setBackgroundImage:[UIImage imageNamed:@"MyImage.png"] forState:UIControlStateNormal];

您可以将状态更改为您喜欢的任何状态.

编辑:如果要从界面构建器添加按钮,请确保将按钮更改Type为Custom,然后更改image.
