私のviewcontrollerA.hには次のものがあります：
@property (nonatomic, assign) NSInteger showCommentOrCreate;
+ (PhotoViewController *) sharedManager;
viewcontrollerA.m で私は使用します:
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;
}
...整数の値を見つける。
viewcontrollerB では ViewcontrollerA.h をインポートし、ViewcontorllerB.m では showCommentOrCreate に値を割り当てます。
唯一の問題は、値を変更するために整数に値を2回割り当てる必要があることです。例えば：
動作しません:
-(IBAction)addAnImageForCommenting:(id)sender{
PhotoViewController* sharedSingleton = [PhotoViewController sharedManager];
sharedSingleton.showCommentOrCreate = 2;
PhotoViewController* sharedSingleton2 = [PhotoViewController sharedManager];
sharedSingleton2.showCommentOrCreate = 2;
}
動作しません:
-(IBAction)addAnImageForCommenting:(id)sender{
PhotoViewController* sharedSingleton2 = [PhotoViewController sharedManager];
sharedSingleton2.showCommentOrCreate = 2;
}

ご覧のとおり、整数の値を 2 回設定すると機能しますが、それ以外の場合は機能しません。そうでない場合、時間間隔を置いてコードを2回呼び出すと、正しい値が設定されます。何か案は？？
