可可 – 在Mac OS X中以编程方式获取屏幕大小

概述我可以返回屏幕尺寸使用： - (void) getScreenResolution { NSArray *screenArray = [NSScreen screens]; NSScreen *mainScreen = [NSScreen mainScreen]; unsigned screenCount = [screenArray count]; unsign 我可以返回屏幕尺寸使用：

- (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：

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

有没有办法格式化{1344，814}到1344×814？

编辑：

这完美工作：

- (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];}

解决方法 NSLog(@“％fx％f”，screenRect.size.wIDth，screenRect.size.height); 总结
