メソッドで View オブジェクトが突然 nil になりました。
私はARCを使用していません
スレッド化は関係ありません
何が起こっているのかというと、最初にその1stmethodメソッドを呼び出すと、すべてが正常に機能し、livescoreSettings への参照が保持されます。
次に2ndmethodメソッドを呼び出すと、livescoreSettings ref も保持されますが、delegate メソッドがアクティブになるまでに、その変数の参照が失われます..理由がわからない...
@interface XY {
LiveScoreSettingsView * livescoreSettings; // initialisation in .h file inside
}
@end
@implementation
// 1st method
- (void)1stmethod:(id) callingClass username:(NSString*)username {
livescoreSettings=callingClass; // retain count increases to 1
isLivescoresSettingsView = YES;
//.... some code where the above livescoreSettings variables are not used ... //
}
// 2nd method
- (void)2ndmethod:(id) callingClass username:(NSString*)username matchid:(NSString *)matchid eventType:(NSString *) eventType add:(NSString *) add {
livescoreSettings=callingClass;
isLivescoresSettingsView = YES;
addEventToList = YES;
//.... some code where the above livescoreSettings variables are not used ... //
}
// delegate method thats activated when the response comes
- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq {
// the block where the data is sent to a particular view to reload table
else if(isLivescoresSettingsView== YES || addEventToList == YES) {
isLivescoresSettingsView=NO;
addEventToList = NO;
//.... some code where the above livescoreSettings variables are not used ... //
if(success)
NSLog(@"No Errors with retain count = %d ", [livescoreSettings retainCount]);
else
NSLog(@"Error Error Error!!!");
[livescoreSettings.tableView reloadData];
// when **2ndmethod** is called there's no memory reference to livescoreSettings, tableView delegate methods are not called which is obvious. But not sure why the retain count is reducing abruptly.
}
