问题描述

如何使用Objective-C从另一个应用程序中获取图标?

How do I get the icon from another application using Objective-C?

到目前为止，我已经尝试过了，但是它只返回null:

I have tried this so far, however it just returns null:

NSURL *path = [NSURL URLWithString:@"/Applications/Calculator.app"];

NSLog(@"%@", path);

NSImage *image = (__bridge NSImage *)(QLThumbnailImageCreate(kCFAllocatorDefault, (__bridge CFURLRef)(path), CGSizeMake(100, 100), (__bridge CFDictionaryRef)(@{(NSString *)kQLThumbnailOptionIconModeKey: @NO})));

NSLog(@"%@", image);

推荐答案

例如，您可以使用NSWorkspace

You can use NSWorkspace, e.g.

NSImage *image = [[NSWorkspace sharedWorkspace] iconForFile:path];

如果您想使用应用程序bundleId而不是知道其路径，则可以先执行此操作

If you want to use the app bundleId instead of knowing its path, you can do this first

path = [[NSWorkspace sharedWorkspace] absolutePathForAppBundleWithIdentifier:bundleIdentifier];
