Synthesize error “Missing Context for Property Implementation Declaration”

问题

Anyone have any ideas? When I try to synthesize a property I have declared in the .h file its not letting me synthesize it. Any ideas? Thanks!

回答1:

This can happen when you attempt to synthesize a property outside of the scope of your class' implementation.

Incorrect:

@synthesize yourProperty;
@implementation YourClass
@end

Correct:

@implementation YourClass
@synthesize yourProperty;
@end

It often happen when you use #import ,and does not on the top of file.
