我创建了自定义 NSPanel 并用 Sheet 开始展示它。它上面没有任何关闭按钮,我想在 10 秒后用 NSTimer 关闭这个面板。我怎样才能做到这一点?
[[NSApplication sharedApplication] beginSheet: scanningPanel
modalForWindow: window
modalDelegate: self
didEndSelector: @selector(sheetDidEnd:returnCode:contextInfo:)
contextInfo: nil];
[[NSApplication sharedApplication] runModalForWindow: scanningPanel];
NSTimer *myTimer = [NSTimer timerWithTimeInterval: 10.0
target:self
selector: @selector(closePanel:) userInfo:nil
repeats:NO];
[[NSRunLoop currentRunLoop] addTimer:myTimer forMode:NSModalPanelRunLoopMode];
closePanel()函数:
-(void) closePanel: (NSTimer *) theTimer
{
NSLog(@"closePanel");
[scanningPanel abortModal]; // seems it not work
}
最佳答案
试试这个:
[NSApp beginSheet:scanningPanel modalForWindow:[self window]
modalDelegate:self
didEndSelector:nil
contextInfo:self];
NSTimer *tm=[NSTimer scheduledTimerWithTimeInterval:1.0
target:self
selector:@selector(closePanel:)
userInfo:nil
repeats:NO];
- (void)closePanel:(NSTimer *)theTimer
{
NSLog(@"closePanel");
[NSApp endSheet:scanningPanel];
[scanningPanel orderOut:self];
}
关于objective-c - 在 Cocoa 中使用 NSTimer 关闭自定义 NSPanel,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/18502229/
