ios - iPhone Simulator stucks on launchscreen. Struct issues in Objective-C? -


this first time using struct in objective-c , can't figure out i'd go wrong. let's me explain better:

in "appdata" class have created struct. instance let's suppose containing information market products.

// struct declaration typedef struct {     int apple;     int banana;     int cherry; } products;   // variable declaration @property (assign, nonatomic) products products;

the first thing app on startup check if keys exist inside nsuserdefault, update products (in order easy access values). way try achieve step:

+ (void)update {     nsuserdefaults *defaultuser = [nsuserdefaults standarduserdefaults];     products updatedproducts;      if ([defaultuser objectforkey:@"apple"] != nil)         updatedproducts.apple = [[defaultuser objectforkey:@"apple"] intvalue];      if ([defaultuser objectforkey:@"banana"] != nil)         updatedproducts.banana = [[defaultuser objectforkey:@"banana"] intvalue];      if ([defaultuser objectforkey:@"cherry"] != nil)         updatedproducts.cherry = [[defaultuser objectforkey:@"cherry"] intvalue];      // update     [[appdata shareddata] setproducts:updatedproducts];      // synchronize     [defaultuser synchronize]; }

the result of infinite in launch screen (the number of nodes , fps not loaded). tried [appdata shareddata].products = updatedproducts; nothing changes.

i'm doing wrong can't figure out what. should do? thanks
