Xcode's does not show any of the ivars in the variable pane when debugging, e.g. when breaking here:
1 // Designated Initializer
2 - (id) initWithRequest:(NSURLRequest*)request
3 connectionThread:(NSThread*)connectionThread
4 {
5 ==> self = [super init];
6 if (self) {
7 _request = [request mutableCopy];
8 _connectionThread = connectionThread;
9 _completionSem = dispatch_semaphore_create(0);
10 _cancelConnectionOnResponseHandlerError = YES;
11 }
12 return self;
13 }
I get this in Xcode's variable pane, which only shows the base class (NSOperation), but not any of the class' own ivars:
v self RXHTTPRequestOperation * 0x00000001003311e0
> NSOperation NSOperation
> other
Variables and properties are declared and defined in the implementation, e.g.:
@implementation RXHTTPRequestOperation {
BOOL _isExecuting;
BOOL _isFinished;
id _result;
dispatch_semaphore_t _completionSem;
int32_t _connectionID;
NSMutableArray* _responseHandlers;
NSHTTPURLResponse* _response;
BOOL _terminating;
…
}
@end
@synthesize isExecuting = _isExecuting;
@synthesize isFinished = _isFinished;
@synthesize result = _result;
@synthesize completionHandler = _completionHandler;
@synthesize response = _httpResponse;
...
I can't remember that I wasn't able to see the variables in other projects. What's going on again?
Well, after playing around with implicitly declared and defined ivars, it turned out that it has a number of caveats - and I likely go back to the convention that all ivars shall be declared explicitly.
