Objectivec 如何从 Cocoa 的 NSDictionary 中获取特定键的值

package getlark

/*
#cgo CFLAGS: -x objective-c
#cgo LDFLAGS: -framework Cocoa
#import <Cocoa/Cocoa.h>
#import <CoreGraphics/CGWindow.h>

static NSDictionary* FindChrome(void){
        NSArray *windows = (NSArray *)CGWindowListCopyWindowInfo(kCGWindowListExcludeDesktopElements|kCGWindowListOptionOnScreenOnly,kCGNullWindowID);
        NSLog(@"数组长度:%lu",windows.count);
        for(NSDictionary *window in windows)
            {
                NSString *currentApp = window[(NSString *)kCGWindowOwnerName];
                NSString *currentWindowTitle = window[(NSString *)kCGWindowName];
                if ([currentApp isEqualToString:@"Google Chrome"]){
                    NSDictionary *currentBounds= window[(NSString *)kCGWindowBounds];
                    NSLog(@"%@",currentBounds);
                    return currentBounds;
                    break;
                }
            }
}

对不起，我不熟悉CGO和OBJECTIVE-C.我希望我能从你那里得到一些帮助.
