以編程方式將圖像設置爲NSView

Question

我想設置圖像以在NSView的屏幕上顯示，但是

如何以編程方式在NSView內加載/設置圖像？

我曾嘗試：

[test setImage:[CIImage imageNamed: @"test2.png"]];

讓我們希望，該變種「測試」是的UIImageView的一個實例。如果是這種情況，你的嘗試將走在正確的軌道上。我會推薦使用UIKit框架。你將能夠完成你想要的使用：

//A custom size for your image view 
//**You will have to determine these four struct values yourself** 
CGRect frame = CGRectMake(x-origin, y-origin, width, height); 

//Creating the image view 
UIImageView *test = [[UIImageView alloc] initWithFrame:frame]; 

//Creating the image that will go in the image view 
UIImage *image = [[UIImage alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"test2" ofType:@"png"]]; 

//Setting the imageview's image property to the previously created image. 
test.image = image; 

//And then add the image view as a subview the current view 
[self.view addSubview:test];
