Question

I want to get property name by self.label1, self.label2, self.label3 etc.
Do you know how to convert NSString to some method like JS or Ruby.

my header is

@property(nonatomic,strong)CCLabelTTF *label1;
@property(nonatomic,strong)CCLabelTTf *label2;...

implementations

for (int i = 0; i < 10; ){

  NSString *str = [NSString stringWithFormat:@"self.label%i",i];
  // convert str to property
  converted_str = [CCLabelTTF labelWithString:%@"hello  below style is  not good...

I want to avoid this style…

for(int i  = 0 ;i < 10;){
   if (i == 0){
   self.label1 = ...
   }else if(i == 1){
   self.label  = ...
}

Do you have any idea? Thanks in advance.

Try using KVC:

NSString *keyPath = [NSString stringWithFormat:@"label%i", labelNumber];

id value = [CCLabelTTF ....];

[self setValue:value forKey:keyPath]; // use KVC to set the value for you
