Example of [NSDictionary getObjects:andKeys:]
- by eagle
I couldn't find a working example of the method [NSDictionary getObjects:andKeys:] on Google. The only link I could find, doesn't compile. I provided the errors/warnings here in case someone is searching for them.
The documentation says that it returns a C array.
NSDictionary *myDictionary = ...;
id objects[]; // Error: Array size missing in 'objects'
id keys[]; // Error: Array size missing in 'keys'
[myDictionary getObjects:&objects andKeys:&keys];
for (int i = 0; i < count; i++) {
id obj = objects[i];
id key = keys[i];
}
.
NSDictionary *myDictionary = ...;
NSInteger count = [myDictionary count];
id objects[count];
id keys[count];
[myDictionary getObjects:&objects andKeys:&keys]; // Warning: Passing argument 1 of 'getObjects:andKeys:' from incompatible pointer type.
for (int i = 0; i < count; i++) {
id obj = objects[i];
id key = keys[i];
}
Please provide a working example of this method.
