Question

嗨我有一个由UIButtons组成的弹出式菜单，我需要在菜单的每个按钮中显示图像。我需要为每个单独的按钮显示不同的图像。共有6个按钮。

我该怎么做

- (NSInteger)makeOneButton:(NSString *)title action:(SEL)action top:(NSNumber *)top into:(UIView *)parent
{
    // NOTE: if you want more stuff here, I'd put all of the items in a view (including this button)

    UIButton * button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [button setTitle:title  forState:UIControlStateNormal];
    //[button setImage:[UIImage imageNamed:@"paper.png"] forState:UIControlStateNormal];
    //UIButtonTypeCustom
    [button addTarget:self action:action forControlEvents:UIControlEventTouchUpInside];
    [button.titleLabel setFont:[UIFont boldSystemFontOfSize:7]];
    [parent addSubview:button];
    [button mas_makeConstraints:^(MASConstraintMaker *make) {
        make.top.equalTo(top);
        make.left.equalTo(parent.mas_left);
        make.width.equalTo(parent);
        make.height.equalTo([NSNumber numberWithInteger:mCurrentCellHeight]);
    }];
    return mCurrentCellHeight;        
}

在此方法中添加另一个参数，即图像名称或图像，并添加为按钮的背景，当您调用此方法添加按钮时，也告诉方法您想要设置相应按钮的图像。像这样....

- (NSInteger)makeOneButton:(NSString *)title action:(SEL)action top:(NSNumber *)top  imageName:(NSString *)imageName into:(UIView *)parent
{
    // NOTE: if you want more stuff here, I'd put all of the items in a view (including this button)

    UIButton * button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    [button setTitle:title  forState:UIControlStateNormal];
    //[button setImage:[UIImage imageNamed:@"paper.png"] forState:UIControlStateNormal];
    //UIButtonTypeCustom
    [button addTarget:self action:action forControlEvents:UIControlEventTouchUpInside];
    [button.titleLabel setFont:[UIFont boldSystemFontOfSize:7]];
    [button setBackgroundImage:[UIImage imageNamed:imageName] forState:UIControlStateNormal];
    [parent addSubview:button];
    [button mas_makeConstraints:^(MASConstraintMaker *make) {
        make.top.equalTo(top);
        make.left.equalTo(parent.mas_left);
        make.width.equalTo(parent);
        make.height.equalTo([NSNumber numberWithInteger:mCurrentCellHeight]);
    }];
    return mCurrentCellHeight;
}
