NSMutableString can add another string or format.

// array must have first object pass 1st parameter
NSMutableString *mutableString = [[NSString alloc] init];
[str appendFormat:"%d", [array objectAtIndex:0].intValue];

// array have second object then pass 2nd parameter
if (2 <= array.count)
   [mutableString appendFormat:"%f", [array objectAtIndex:0].floatValue]];

NSLog("%@", mutableString);

You forgot to add Escape character for '%' this sign. Try below code it will work.

int i=2;
NSString *output= [NSString stringWithFormat:@"%%.%if",i];

if you want to display two values then you can try below. 

int i=2;
float x=3.5;
NSString *output= [NSString stringWithFormat:@"%%.%if  %%.%ff",i,x];

Please modify as you need. This is just for your idea how to use it.

You can't nest format string, you could do it like this:

int value = [[arrayvalue objectAtIndex:0] intValue];
NSString *string = [@"%." stringByAppendingFormat:@"%if", value];
string = [NSString stringWithFormat:string, [textField2.text floatValue]];

This is code is totally untested.
