我想显示工作表,当用户单击“确定”时,显示另一张工作表。依次显示NSAlert工作表模式

然而,点击“确定”的时刻整个设计变得混乱,好像第一张警报表没有足够的时间消失。

这是我使用的床单代码:

#define CONFIRM_ALERT(X,Y,Z,W,V) \ 
NSAlert* confirmAlert = [NSAlert alertWithMessageText:X \ 
defaultButton:@"OK" \ 
alternateButton:@"Cancel" \ 
otherButton:nil \ 
informativeTextWithFormat:Y]; \ 
[confirmAlert beginSheetModalForWindow:Z \ 
modalDelegate:self \ 
didEndSelector:W \ 
contextInfo:V]; 

#define INFO_ALERT(X,Y,Z) \ 
NSAlert *infoAlert = [[NSAlert alloc] init]; \ 
[infoAlert addButtonWithTitle:@"OK"]; \ 
[infoAlert setMessageText:X]; \ 
[infoAlert setInformativeText:Y];\ 
[infoAlert setAlertStyle:NSInformationalAlertStyle]; \ 
[infoAlert beginSheetModalForWindow:Z modalDelegate:self didEndSelector:nil contextInfo:nil]; 

而我如何使用它:

- (void)doSth 
{ 
     CONFIRM_ALERT(@"New Action", 
       @"Are you sure you want to proceed?", 
       [self window], 
       @selector(confirm:code:context:), 
       nil); 
} 

- (void)confirm:(NSAlert*)alert code:(int)choice context:(void *)filename 
{ 
    if (choice == NSAlertDefaultReturn) 
    { 
     INFO_ALERT(@"Success :-)", 
     @"The Action has been successfully completed.", 
     [self window]); 
    } 
} 

任何想法?我究竟做错了什么?

您必须通过使用performSelector:withObject:afterDelay或等效方法延迟显示下一个运行循环中的工作表。
