UIImageView - Displaying an image from Directory
提问by Stephen
I have the following code in place:
我有以下代码：
- (void)viewDidLoad {
NSString *homeDirectoryPath = NSHomeDirectory();
NSString *imagePath = [homeDirectoryPath stringByAppendingString:@"/graph.png"];
NSLog(@"Image: %@", imagePath);
if (![[NSFileManager defaultManager] fileExistsAtPath:imagePath isDirectory:NULL])
{
graph = imagePath;
//[[NSFileManager defaultManager] createDirectoryAtPath:imagePath attributes:nil];
}
'graph' is defined as UIImageView. I'm trying to display the file in the path 'imagePath'. I know the code graph = imagePath is not correct, as the variable 'imagePath' states it contains the path to the image.
'graph' 被定义为 UIImageView。我正在尝试在路径“imagePath”中显示文件。我知道代码图 = imagePath 不正确，因为变量 'imagePath' 声明它包含图像的路径。
How would I display my image located at the specific image path ?
我将如何显示位于特定图像路径的图像？
Regards, Stephen

You'll have to create an imageview object, set it as the image view's image and release the image you created:
您必须创建一个图像视图对象，将其设置为图像视图的图像并释放您创建的图像：
UIImage *graphImage = [[UIImage alloc] initWithContentsOfFile: imagePath];
graph.image = graphImage;
[graphImage release];
