Question

@interface MainView : UIView { 
    NSMutableString *mutableString; 
}
@property (nonatomic, retain) NSMutableString *mutableString;
@end

@implementation MainView
@synthesize mutableString;

-(void) InitFunc {  
    self.mutableString=[[NSMutableString alloc] init];
 }

-(void) AppendFunc:(*NString) alpha { 
    [self.mutableString stringByAppendingString:@"hello"];
    NSLog(@"the appended String is: %@",self.mutableString);
    int len=[self.mutableString length];
}

Hey Everyone,

i just want to know where I am doing wrong ??? . I tried this code but “mutableString” does not append any value (as value of “len”comes ‘0’ and NSLog doesnt print any value for “mutableString”), though i ve searched on net for the solution, people implemented in the same fashion yet i dont know why my code isnt working.

Thanks in Advance

Answer 1

stringByAppendingString: creates new string. Use appendString: instead:

[mutableString appendString:@”hello”]
