int *SliderMaximum = V1.TeamAmountAfterSave;
[sliderTeamSelect setmaximum:SliderMaximum];
I need to convert SliderMaximum to a float how do I do this?
NSNumber *yourNumber = [NSNumber numberWithInt: SliderMaximum];
float yourFloat = [yourNumber floatValue];
and you don't need a pointer to int, it's useless, computationally allocate a pointer and write inside address pointer to int is same as allocate a int and write int in it.
Have you tried multiplying it by a float?
CGFloat sliderMaximum = SliderMaximum * 1.0f;
[sliderTeamSelect setmaximum:[[V1.TeamAmountAfterSave] floatValue]];

Improve this question
nsnumber *totaldur=0;
totalDur+=(NSNumber*)[dict valueForKey:#"tracktime"];
You can't perform addition on NSnumber for this
NSNumber * totaldur =[NSNumber numberWithInteger:20];
totaldur = [NSNumber numberWithInteger:([number1 integerValue] + [[dict valueForKey:#"tracktime"] integerValue])];
//// first of all convert both numbers to same data type like (nsinteger,int,float) and then apply addition on them and in the end save sum in nsnumber object
Hope it helps

I am teaching myself Objective - C and I tried out some code to do a math equation. Can you please tell me what I am doing wrong?
- (IBAction)mathEquation:(id)sender {
int a = 6;
int b = 2;
self.showAnswer.text = int a + int b;
}
Can someone please rewrite to code the correct way and post it? Thank you!
int result = a + b;
self.showAnswer.text = [NSString stringWithFormat:#"%d", result];
In Objective-C, you can't just assign a number to a string, it won't work. As you see in my code, you need to convert from a numerical value into a string. The method [NSString stringWithFormat:] lets you do that, and what kind of number(s) you want to include in the string. E.g. the format expression %d is for an integer value.
Also, once you declared your variables (int a, etc.), you don't need to declare them again, you'll get an error.
I would strongly advice reading up on the basic syntax of Objective-C.

I know setting a variable conditionally is valid:
someProperty = [anObject aFunctionThatReturnsBool]? #"Yes" : #"No";
This question has an answer that details the use of ternary statements in preprocessor macros
#define statusString (statusBool ? #"Approved" : #"Rejected")
and within a string formatting method
[NSString stringWithFormat: #"Status: %#", (statusBool ? #"Approved" : #"Rejected")]
But what about within any method?
[NSNumber numberWithInt:(aVariableThatCouldBeSet)? 100 : 0)];
And conditional method calling?
[anObject aFunctionThatReturnsBool]? [self doThis] : [self doThat];
Bonus points for any other uses not listed.

-(IBAction)button:(id)sender{
If (cardsinplay >= 16){
NSNumber *cardValue = carsAndValue[14];
NSInteger *Value = [cardValue integerValue[;
From what i know this should read the NSNumber from the array and change it into a NSInteger
But i get this error.
Incompatible integer to pointer conversion initialization 'NSInteger*'(aka 'int*') with an expression of type 'NSInteger'(aka 'int*')
-[NSNumber integerValue] returns a NSInteger, not a pointer to one.
NSInteger *Value = [cardValue integerValue];
should be
NSInteger value = [cardValue integerValue];
