以编程方式在Mac OS X中获取屏幕大小 [英] Programmatically get screen size in Mac OS X

问题描述

我可以使用以下命令返回屏幕尺寸：

I am able to return the screen size using:

- (void) getScreenResolution {

    NSArray *screenArray = [NSScreen screens];
    NSScreen *mainScreen = [NSScreen mainScreen];
    unsigned screenCount = [screenArray count];
    unsigned index  = 0;

    for (index; index < screenCount; index++)
    {
      NSScreen *screen = [screenArray objectAtIndex: index];
      NSRect screenRect = [screen visibleFrame];
      NSString *mString = ((mainScreen == screen) ? @"Main" : @"not-main");

      NSLog(@"Screen #%d (%@) Frame: %@", index, mString, NSStringFromRect(screenRect));
    }
}

输出 p>

Output:

屏幕＃0（主）框架：{{0,4}，{1344,814}}

Screen #0 (Main) Frame: {{0, 4}, {1344, 814}}

有没有办法将 {1344,814} 格式化为 1344x814 ？

Is there a way to format {1344, 814} to 1344x814?

这完美地工作：

- (NSString*) screenResolution {

    NSRect screenRect;
    NSArray *screenArray = [NSScreen screens];
    unsigned screenCount = [screenArray count];
    unsigned index  = 0;

    for (index; index < screenCount; index++)
    {
        NSScreen *screen = [screenArray objectAtIndex: index];
        screenRect = [screen visibleFrame];
    }

    return [NSString stringWithFormat:@"%.1fx%.1f",screenRect.size.width, screenRect.size.height];
}

推荐答案

NSLog（@％fx％f，screenRect.size.width，screenRect.size.height）;
