Question

所以我一直试图在导航栏上设置左侧栏按钮的样式。主要是按钮样式我不想取样（与UIButton样式设置为自定义相同的样式）。

有谁知道怎么做？谢谢，詹姆斯

在JASidePanelController.m中查看此函数

+ (UIImage *)defaultImage {
    static UIImage *defaultImage = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        UIGraphicsBeginImageContextWithOptions(CGSizeMake(20.f, 13.f), NO, 0.0f);

        [[UIColor blackColor] setFill];
        [[UIBezierPath bezierPathWithRect:CGRectMake(0, 0, 20, 1)] fill];
        [[UIBezierPath bezierPathWithRect:CGRectMake(0, 5, 20, 1)] fill];
        [[UIBezierPath bezierPathWithRect:CGRectMake(0, 10, 20, 1)] fill];

        [[UIColor whiteColor] setFill];
        [[UIBezierPath bezierPathWithRect:CGRectMake(0, 1, 20, 2)] fill];
        [[UIBezierPath bezierPathWithRect:CGRectMake(0, 6,  20, 2)] fill];
        [[UIBezierPath bezierPathWithRect:CGRectMake(0, 11, 20, 2)] fill];   

        defaultImage = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();

    });
    return defaultImage;
}

这是在customButton上创建3行的部分。

这被称为：

- (UIBarButtonItem *)leftButtonForCenterPanel {
    return [[UIBarButtonItem alloc] initWithImage:[[self class] defaultImage] style:UIBarButtonItemStylePlain target:self action:@selector(toggleLeftPanel:)];
}

因此，将其定制为例如：

- (UIBarButtonItem *)leftButtonForCenterPanel {
UIImage *faceImage = [UIImage imageNamed:@"facebook.png"];
UIButton *face = [UIButton buttonWithType:UIButtonTypeCustom];
face.bounds = CGRectMake( 0, 0, faceImage.size.width, faceImage.size.height );
[face setImage:faceImage forState:UIControlStateNormal];
[face addTarget:self 
             action:@selector(toggleLeftPanel:) 
   forControlEvents:UIControlEventTouchUpInside];
return [[UIBarButtonItem alloc] initWithCustomView:face];
}

请根据您的具体情况进行更改。希望这会有所帮助...
