在我的 viewcontrollerA.h 我有：
@property (nonatomic, assign) NSInteger showCommentOrCreate;
+ (PhotoViewController *) sharedManager;
在 viewcontrollerA.m 我使用：
PhotoViewController* sharedSingleton = [PhotoViewController sharedManager];
...(long)sharedSingleton.showCommentOrCreate...
+ (PhotoViewController *)sharedManager
{
static PhotoViewController *shaderManager = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
shaderManager = [[PhotoViewController alloc] init];
});
return shaderManager;
}
...找到整数的值。
在 viewcontrollerB 中，我导入 ViewcontrollerA.h，在 ViewcontorllerB.m 中，我将一个值赋予 showCommentOrCreate。
唯一的问题是它接缝我必须将值分配给整数两次才能更改。例如：
不起作用：
-(IBAction)addAnImageForCommenting:(id)sender{
PhotoViewController* sharedSingleton = [PhotoViewController sharedManager];
sharedSingleton.showCommentOrCreate = 2;
PhotoViewController* sharedSingleton2 = [PhotoViewController sharedManager];
sharedSingleton2.showCommentOrCreate = 2;
}
不起作用：
-(IBAction)addAnImageForCommenting:(id)sender{
PhotoViewController* sharedSingleton2 = [PhotoViewController sharedManager];
sharedSingleton2.showCommentOrCreate = 2;
}

如您所见，我将整数的值设置了两次，它有效，否则无效。如果没有，如果我以时间间隔调用代码两次，则设置正确的值。有任何想法吗？？
