Q:
How to dynamically add and remove an object in a linear array
I have a NSMutableArray named myArray, I have an object with a value and a key I want to add and remove in this array, I made this method:
-(void)addObjectWithKey:(NSString*)key withValue:(id)value{
NSMutableArray *newArray = [[NSMutableArray alloc] init];
[newArray addObject:value];
//What to do now?
}
I don't know how to add the key and the value, I don't know if I need to declare newArray before adding elements, so I don't know how to remove elements from an array in objective-c.
A:
Try:
- (void)addObjectWithKey:(NSString *)key withValue:(id)value{
[myArray addObject:[NSArray arrayWithObjects:value, key, nil]];
}
Note:
The + addObject: is part of the NSArray Class and it returns an NSArray object
The [] arrayWithObjects: is part of the NSArray Class and it return an NSArray object.
By the way, you can also do:
- (void)addObjectWithKey:(NSString *)key withValue:(id)value{
NSMutableArray *newArray = [[NSMutableArray alloc] init];
[newArray addObject:value];
[newArray addObject:key];
[myArray addObject:newArray];
}
Votum

A votum is a vow, and a votum with a formula is a vow formula.
