EDIT To answer your question below.
while ([scanner scanFloat:&myVariable] && [scanner scanFloat:&myVariable2] && [scanner scanFloat:&myVariable3]) {
[NSMutableDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithFloat:myVariable], #"theKeyInTheCSV",
[NSNumber numberWithFloat:myVariable2], #"theKeyInTheCSV2",
[NSNumber numberWithFloat:myVariable3], #"theKeyInTheCSV3",
nil]];
}

Answer 2

her is my code:
-(IBAction)Zollamtsname:(id)sender{
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"Zollämter Access" ofType:#"csv"];
NSString *myText = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil ];
NSLog(#"%#", [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil]);
if ( nil == mytext ) return NO;
NSScanner *scanner = [NSScanner scannerWithString:myText];
[scanner setCharactersToBeSkipped:
[NSCharacterSet characterSetWithCharactersInString:#"\n, "]];
NSMutableArray *newPoints = [NSMutableArray array];
float test1, test2;
while ( [scanner scanFloat:&test1] && [scanner scanFloat:&test2] ) {
[newPoints addObject:
[NSMutableDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithFloat:test1], #"test1",
[NSNumber numberWithFloat:test2], #"test2",
nil]];
}
[self setPoints:newPoints];
return YES;
}
//[self.Zollamzsnummer setText:#"test"];
}
i get 4 errors and I don't know how so solve them :( 1."return NO" = the void method should not return a value
2. "return YES" = the void method should not return a value
3. [self setPoints:newPoints]; = Not visible #interface for'ViewController_suche'declares the selector setPoints
ANd who I say that the serach value is in the textfield?
