Question

I have in the .h file :

NSString *dataHML; 
NSString *dataHML2;
NSString *dataHML3;
NSString *dataHML4;
NSString *dataHML5;
NSString *dataHML6;
NSString *dataHMLtotal;

in the .m file I merge them with :

NSString *dataHtmlTotal = [NSString stringWithFormat:@"%@%@%@%@%@%@", dataHtml, dataHtml2, dataHtml3, dataHtml4,dataHtml5,dataHtml6];

But unfortunately it crashes at some point because of this.
Could anyone give me a other solution and post it please, because I already tried nsuserdefault or a nsarray, but without I couldn’t get it working.

Answer 1

If you really do have 6 variables numerically named like that, you could be better off with an array.

NSMutableArray *dataHMLStrings = [NSMutableArray array];

[dataHMLStrings addObject:@"String1"];
[dataHMLStrings addObject:@"String2"];
            .
            .
            .
[dataHMLStrings addObject:@"String100"]; // or however many you have.

NSString *dataHMLTotal = [dataHMLStrings componentsJoinedByString:@""];

You can give the componentsJoinedByString: method a different string (I passed an empty string here because you didn’t want anything to appear between each dataHML string).
