Answer 1

Sample code NSMutableString:

NSMutableString* mutString = [[NSMutableString alloc] init];
    for(int index=0;index<10;index++)
    {
        [mutString appendString:[NSString stringWithFormat:@"%d",index]];
    }
    NSLog(@"Content in MutableString: %@",mutString);

Regarding crash: post your code that crashes. What does it say ?

Answer 2

There is a crash when you try to append nil to a NSMutableString - check that. Also while it does not crash during append - if your NSMutablestring is not initialized - then nothing works and your app might crash later in the code because there is nothing in your string. Post the crash report, I am sure it will tell you what is going wrong.
