Question

我使用下面的代码加载图像是在上面，下半部分是按钮的标题，但只有图像，这是为什么？有任何好的建议请告诉我们，谢谢

UIButton *myButton = [[UIButton alloc]initWithFrame:CGRectMake(160, 400, 73, 44)];

    [myButton setImage:[UIImage imageNamed:@"icon.png"] forState:UIControlStateNormal];
    [myButton setImageEdgeInsets: UIEdgeInsetsMake(0,0,22,0)];

    [myButton setTitle:@"test" forState:UIControlStateNormal];
    [myButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [myButton setTitleEdgeInsets: UIEdgeInsetsMake(22,10,0,10)];

    [self.view addSubview:myButton];

你也可以通过这种方式实现这种效果..试试这个::

UIButton *myButton = [[UIButton alloc]initWithFrame:CGRectMake(160, 400, 73, 55)];
UIImage *img = [UIImage imageNamed:@"icon.png"];
UIImageView *imgVw = [[UIImageView alloc ] init];
imgVw.image  = img;
imgVw.frame = CGRectMake(myButton.frame.origin.x, myButton.frame.origin.y, myButton.frame.size.width, (myButton.frame.size.height-18));
[myButton setTitle:@"test" forState:UIControlStateNormal];
[myButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[myButton setTitleEdgeInsets: UIEdgeInsetsMake(34,10,0,10)];
[myButton addTarget:self action:@selector(btnClick:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:imgVw];    
[self.view addSubview:myButton];

您的按钮方法

-(void) btnClick:(id)sender
{
    NSLog(@"working");
}

你也可以从你的逻辑中实现::这里我已经在你的逻辑中编辑了一些代码

UIButton *myButton = [[UIButton alloc]initWithFrame:CGRectMake(160, 400, 40, 35)];
[myButton setImage:[UIImage imageNamed:@"icon.png"] forState:UIControlStateNormal];
[myButton setImageEdgeInsets:UIEdgeInsetsMake(0,(myButton.frame.size.width-52),17,0)];
[myButton setTitle:@"test" forState:UIControlStateNormal];
[myButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[myButton setTitleEdgeInsets: UIEdgeInsetsMake(22,(myButton.frame.size.width-78),0,22)];
[self.view addSubview:myButton];

但是，在此逻辑中，您必须将图像大小调整为23 * 23像素。根据您的图片尺寸 UIEdgeInsetsMake 的参数将被更改。

希望这会有所帮助。快乐的编码。
