通知崩潰應用程序

-1

我想通過NSMutableDictionary到NSNotification其他類。但是當釋放NSMutableDictionary應用程序崩潰。任何人都可以幫忙嗎？我正在試圖通知崩潰應用程序

NSMutableDictionary *temp = [[NSMutableDictionary alloc]init]; 

NSString *responseString = [[NSString alloc] initWithData:webData encoding:NSUTF8StringEncoding]; 
temp = [responseString JSONValue]; 
NSLog(@"webdata is %@",temp); 
NSLog(@"inside usersignup success"); 
[[NSNotificationCenter defaultCenter] postNotificationName:CNotifySignupSucess object:temp]; 
[temp release];

[[NSNotificationCenter defaultCenter] addObserver：self selector：@selector（signupsucessreceived :) name：CNotifySignupSucess object：nil]; – jpd 2013-03-06 05:20:52

NSMutableDictionary * dict = notification.object;如果（[[dict objectForKey：@「Success」] isEqualToString：@「1」]） { appDelegate.islogin = TRUE; self.title = nil; [appDelegate.userinfo setObject：[dict objectForKey：@「user_id」] forKey：@「userid」]; NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults]; NSString * strtemp = [NSString stringWithFormat：@「％@」，[dict objectForKey：@「user_id」]]; [默認setObject：strtemp forKey：@「userid」]; – jpd 2013-03-06 05:21:38

首先，您需要閱讀一些iOS編程基礎知識。而且，

NSMutableDictionary *temp = [[NSMutableDictionary alloc]init]; 

NSString *responseString = [[NSString alloc] initWithData:webData encoding:NSUTF8StringEncoding]; 
temp = [responseString JSONValue]; //----> this line is wrong

因爲，temp指針指向新創建NSMutableDictionary對象時，你重新分配給由JSONValue方法，這是autorelease對象返回另一個對象，你並不擁有它，從而可以」 t release它。一些更好的方法來達到想要你想會是：

NSString *responseString = [[NSString alloc] initWithData:webData encoding:NSUTF8StringEncoding]; 
    NSMutableDictionary *temp = [responseString JSONValue]; 
    NSLog(@"webdata is %@",temp); 
    NSLog(@"inside usersignup success"); 
    [[NSNotificationCenter defaultCenter] postNotificationName:CNotifySignupSucess object:temp]; 
    //NO RELEASING the AUTORELEASE OBJECT!!!!

OR：

NSString *responseString = [[NSString alloc] initWithData:webData encoding:NSUTF8StringEncoding]; 
    NSMutableDictionary *temp = [[NSMutableDictionary alloc]initWithDictionary:[responseString JSONValue]]; 
    NSLog(@"webdata is %@",temp); 
    NSLog(@"inside usersignup success"); 
    [[NSNotificationCenter defaultCenter] postNotificationName:CNotifySignupSucess object:temp]; 
    [temp release];

OR：

NSMutableDictionary *temp = [[NSMutableDictionary alloc]init]; 

    NSString *responseString = [[NSString alloc] initWithData:webData encoding:NSUTF8StringEncoding]; 
    [temp addEntriesFromDictionary:[responseString JSONValue]]; 
    NSLog(@"webdata is %@",temp); 
    NSLog(@"inside usersignup success"); 
    [[NSNotificationCenter defaultCenter] postNotificationName:CNotifySignupSucess object:temp]; 
    [temp release];

在過去的2情況下，我正在考慮是JSONValue方法返回NSDictionary 。祝你好運！
