ios - UIButton 背景边框问题 iOS

Question

我的应用程序中有一个带有背景图片的 UIButton，就是这个

我想让它更长一些，并在我的代码中添加了以下内容:

UIImage *backgroundButton = [UIImage imageNamed:@"Button.png"];
        [backgroundButton resizableImageWithCapInsets:UIEdgeInsetsMake(10, 10, 10, 10)];
        [backgroundButton imageWithAlignmentRectInsets:UIEdgeInsetsMake(10, 10, 10, 10)];

        [self.loginButton setBackgroundImage:[backgroundButton imageWithAlignmentRectInsets:UIEdgeInsetsMake(10, 10, 10, 10)] forState:UIControlStateNormal];

我试图设置一些边距来避免这种情况

如何获得与第一个按钮相同但尺寸相同的结果？在此先感谢您的支持

我将把这两种方法都提供给我们的开发人员

耶稣:

[self.loginButton setBackgroundImage:[[UIImage imageNamed:@"Button.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(10, 8, 10, 8)] forState:UIControlStateNormal];

游戏大会:

UIImage *modifiedBackgroundButton = [backgroundButton resizableImageWithCapInsets:UIEdgeInsetsMake(10, 10, 10, 10)];
        [self.loginButton setBackgroundImage:[modifiedBackgroundButton imageWithAlignmentRectInsets:UIEdgeInsetsMake(10, 10, 10, 10)] forState:UIControlStateNormal];

        [backgroundButton resizableImageWithCapInsets:UIEdgeInsetsMake(10, 10, 10, 10)];
        [backgroundButton imageWithAlignmentRectInsets:UIEdgeInsetsMake(10, 10, 10, 10)];

我喜欢这两个答案耶稣非常精确，gameCon 使用我自己的代码来帮助我感谢大家的帮助!!!

正如我们所看到的，您的拉伸(stretch)背景图像实际上没有设置 cap insets。您必须存储并处理此方法的结果(此代码实际上什么都不做):

[backgroundButton resizableImageWithCapInsets:UIEdgeInsetsMake(10, 10, 10, 10)];
[backgroundButton imageWithAlignmentRectInsets:UIEdgeInsetsMake(10, 10, 10, 10)];

所以正确的做法是:

UIImage *modifiedBackgroundButton = [backgroundButton resizableImageWithCapInsets:UIEdgeInsetsMake(10, 10, 10, 10)];
[self.loginButton setBackgroundImage:[modifiedBackgroundButton imageWithAlignmentRectInsets:UIEdgeInsetsMake(10, 10, 10, 10)] forState:UIControlStateNormal];
