Iphone 将URL图像添加到按钮单击

我在一些教程中搜索了将UIImage添加到click事件的按钮。如何添加URL路径

图像到按钮..例如代码：

UIButton *imageView=[[UIButton alloc]initWithFrame:CGRectMake((320*index)+countFlag*80+ 2, 5, 75, 75)];
                imageView.tag=i+1;
                [imageView addTarget:self action:@selector(imageViewClicked:) forControlEvents:UIControlEventTouchUpInside];
                [imageView.layer setBorderColor:[UIColor lightGrayColor].CGColor];
                [imageView.layer setBorderWidth:1.0f];
                switch ((i+1)%5) {
                    case 0:
                        [imageView setImage:[UIImage imageNamed:@"img1.png"] forState:UIControlStateNormal];               

                        break;

                    case 1:
                        [imageView setImage:[UIImage imageNamed:@"img2.png"]  forState:UIControlStateNormal];

                        break;
    }

为ur按钮（imageView）尝试此操作

对于正常状态

[imageView setImage:[UIImage imageNamed:@"img1.png"] forState:UIControlStateNormal];

对于单击的（选定的）状态

希望这会有所帮助。

试试这个：

    EGOImageButton* btnUserImage = [[EGOImageButton alloc] initWithPlaceholderImage:[UIImage imageNamed:@"ProfilePictureDefault.png"]];
    btnUserImage.frame = CGRectMake(10,5,25,25);
    btnUserImage.highlighted = NO;
    [self addSubview:btnUserImage];

    btnUserImage.imageURL = [NSURL URLWithString:Url];

最好使用这个

UIButton+WebCache.h

类别，它支持异步加载按钮的图像。您可以使用以下任何方法

- (void)setImageWithURL:(NSURL *)url forState:(UIControlState)state;
- (void)setImageWithURL:(NSURL *)url forState:(UIControlState)state placeholderImage:(UIImage *)placeholder;

它还为

ui按钮

- (void)setBackgroundImageWithURL:(NSURL *)url forState:(UIControlState)state;
- (void)setBackgroundImageWithURL:(NSURL *)url forState:(UIControlState)state placeholderImage:(UIImage *)placeholder;

不要忘记将

SDWebImage

包含到项目中，并将

UIButton+WebCache.h

文件包含到实现文件中

参考：

要显示带有背景图像的按钮吗？使用EGOButton作为URL。使用哪个ios版本r us？为imageview或uibutton设置图像？使用ios 6.1，将图像设置为uibutton。UIButton*imageView=[[UIButton alloc]initWithFrame:CGRectMake（（320*index）+countFlag*80+2,5,75,75）]；tag=i+1；[imageView添加目标：自我操作：@选择器（imageView单击：）用于控制事件：UIControlEventTouchUpInside]；[imageView.layer setBorderColor:[UIColor lightGrayColor].CGColor]；[imageView.layer-Width:1.0f]；它起作用了。谢谢..那么是否可以将多个url加载到uibutton？

    EGOImageButton* btnUserImage = [[EGOImageButton alloc] initWithPlaceholderImage:[UIImage imageNamed:@"ProfilePictureDefault.png"]];
    btnUserImage.frame = CGRectMake(10,5,25,25);
    btnUserImage.highlighted = NO;
    [self addSubview:btnUserImage];

    btnUserImage.imageURL = [NSURL URLWithString:Url];

- (void)setImageWithURL:(NSURL *)url forState:(UIControlState)state;
- (void)setImageWithURL:(NSURL *)url forState:(UIControlState)state placeholderImage:(UIImage *)placeholder;

- (void)setBackgroundImageWithURL:(NSURL *)url forState:(UIControlState)state;
- (void)setBackgroundImageWithURL:(NSURL *)url forState:(UIControlState)state placeholderImage:(UIImage *)placeholder;
