Hallo,
i am totally new to cocoa and have a simple question with NSString:

How can i init a NSString with an float value?

Ok. I can do this with

float viewSize="34.3333333"; or so

sprintf(tempStr, "%.1f",viewSize);
viewSizeStr = [[NSString alloc] initWithCString:tempStr];

but tempStr must have a allocate buffer.

How can I use initWithFormatNSString *)format argumentsva_list)argList?

I try to do it this way but it doesn't work, why?

viewSizeStr = [[NSString alloc] initWithFormat:@"%.1f" arguments:"viewSize"];

Can someone help?
Thanx

try something like:

NSString *s;
float viewSize = 34.3333333;

s = [[NSNumber numberWithFloat:viewSize] stringValue];

Thanx,
but that seems not to be the dirct way.

Fortuantly i found a way

viewSizeStr = [NSMutableString localizedStringWithFormat:@"%.1f %@", viewSize ,valueExtensionStr];

which add also an text extension to the string, like a kB or MB

you can also do this with an NSString.
