Question

For this code example below, usually I would use [self fall]; instead of the code at *, but I need the value of i to be sent to the fall method as well. How do I do this?

- (void)main {
    for (int i=0; i <= 100; i++) {
        [image[i] fall]; *
    }
}

- (void)fall {
    // manipulate image[i]; separately from the for loop
}

EDIT: I will accept the oldest answer as all are correct. Thanks!

You need to do –

 - (void)fall:(int)i {
     // manipulate image[i]; separately from the for loop
}

and call like –

- (void)main {
for (int i=0; i <= 100; i++) {
    [image fall:i];
}

}

EDIT –

If you want to pass index-

 - (void)fall:(int)i {
     // manipulate image[i]; separately from the for loop
}

and call like –

- (void)main {
for (int i=0; i <= 100; i++) {
    [self fall:i]; // Now from here you can either pass index
}

}

If you want to pass some image –

 - (void)fall:(UIImage)i {
     // manipulate image[i]; separately from the for loop
}

and call like –

- (void)main {
for (int i=0; i <= 100; i++) {
    [self fall:imageI]; // Now from here you need to pass image, if that image is stored in array, then fetch from array. Or you need to manipulate in the way in which you are storing.
}
