UIButtonTypeRoundedRect的框架

Question

对于UIButton我正在使用第一个UIButtonTypeCustom现在我想将其更改为RoundedRect但是当我将UIButtonTypeCustom更改为UIButtonTypeRoundedRect时，它会显示白色的RoundedRect而不是为其指定的颜色，并且它显示在roundrect按钮后面的rect buttonframe的边缘。所以我想知道如何解决这个问题。

UIButton *myButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];

[myButton addTarget:self action:@selector(dismissView:) forControlEvents:UIControlEventTouchUpInside];

myButton.frame = CGRectMake(0, 0, 60, 30);

[myButton setTitle:@"Done" forState:UIControlStateNormal];

myButton.backgroundColor = [UIColor colorWithHue:1.0/12 saturation:2.0/3 brightness:4.0/10 alpha:1.0];

UIBarButtonItem *button = [[UIBarButtonItem alloc] initWithCustomView:myButton];

[[self navigationItem] setLeftBarButtonItem:button animated:YES];

感谢您的帮助。

嗯......我担心如果它是UIButton，就无法更改UIButtonTypeRoundedRect的backgroundColor。

我的建议是创建UIButtonTypeCustom并更改其图层以模仿UIButtonTypeRoundedRect。

试试这段代码：

#import <QuartzCore/QuartzCore.h>

[myButton.layer setMasksToBounds:YES];
[myButton.layer setCornerRadius:10.0f];
[myButton.layer setBackgroundColor:[UIColor whiteColor].CGColor;
