通知崩溃应用程序

-1

我想通过NSMutableDictionary到NSNotification其他类。但是当释放NSMutableDictionary应用程序崩溃。任何人都可以帮忙吗？我正在试图通知崩溃应用程序

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”]]; [默认setObject：strtemp forKey：@“userid”]; – jpd 2013-03-06 05:21:38

首先，您需要阅读一些iOS编程基础知识。而且，

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

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

因为，temp指针指向新创建NSMutableDictionary对象时，你重新分配给由JSONValue方法，这是autorelease对象返回另一个对象，你并不拥有它，从而可以” t release它。一些更好的方法来达到想要你想会是：

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];

在过去的2情况下，我正在考虑是JSONValue方法返回NSDictionary 。祝你好运！
