objective c - Memory leak on calling API using sharedInstance resulting in crashin IOS -


i created sharedinstance code below:

 + (myclass *)sharedstore     {         @synchronized(self)         {             if (sharedinstance == nil)                sharedinstance = [[self alloc] init];         }         return sharedinstance;     }

i have function in myclass

- (myclass *)initservice:(int)servicetype areaselected :(int)areaid target:(id)delegate {      self = [super init];     // again init function called after having shared instance resulting in memory leak.      if(self)     {         jsonparserobject = [[myclassinfoparser alloc]init];         if(jsonparserobject != nil)         {             servicetyperequested = servicetype;                  selectedareaid = areaid;                 nsstring *url = [self createurlandbodyforservice];                 nslog(@"url : %@",url);                 if ([reachability connected])                 {                     if(url.length)                     {                         bool status =  [self initrequest:url withdelegate:delegate];                         if(status)                             nslog(@"request fields successfully");                         else                             nslog(@"failed send request fields");                     }                     else                     {                          [super responsefailednotification:nil];                     }                 }             else             {                 [super networkerror:delegate];             }          }      }     return self; }

to call above function use code 

   - (void)startserviceforinformation     {         serviceobj = [[myclass sharedstore]initservice:2 areaselected:self.areaid target:self];         [serviceobj start];      }

this resulting in memory leak results in crash.can me out fix memory leak?

well, why init method when using singleton class?there no need second init method make method , call singleton instance

try this

- (void)startservice:(int)servicetype areaselected :(int)areaid target:(id)delegate {         jsonparserobject = [[myclassinfoparser alloc]init];         if(jsonparserobject != nil)         {             servicetyperequested = servicetype;              selectedareaid = areaid;             nsstring *url = [self createurlandbodyforservice];             nslog(@"url : %@",url);             if ([reachability connected])             {                 if(url.length)                 {                     bool status =  [self initrequest:url withdelegate:delegate];                     if(status)                         nslog(@"request fields successfully");                     else                         nslog(@"failed send request fields");                 }                 else                 {                     [super responsefailednotification:nil];                 }             }             else             {                 [super networkerror:delegate];             }         } }

and call

- (void)startserviceforinformation     {         serviceobj = [[myclass sharedstore]startservice:2 areaselected:self.areaid target:self];         [serviceobj start];      }

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
