Question

Here’s my @interface def;

@interface Thumbnail : UIView <NSCoding>{
    NSMutableString *imageCacheKeyBase;
}
@property (nonatomic, copy) NSMutableString  *imageCacheKeyBase;
@end

Here’s my @implementation:

@synthesize imageCacheKeyBase;

Then in a method called initWithAsset in the Thumbnail class:

self.urlString = [[_asset.defaultRepresentation.url absoluteString] copy];
c  = (char*)[urlString UTF8String];

while (*c != '=') 
    ++c;
++c;

self.imageCacheKeyBase = [NSString stringWithFormat:@"%s_", c];

And, so when the Thumbnail allocing class tries to reference thumbnail.imageCacheKeyBase the stinkin’ thing is nil. I’ve tried a million different approaches to getting a string variable to stick as a property of thumbnail. I even tried simply self.imageCacheKeyBase = @”dave”. Nuthin’. I’ve tried retain and retain retain (I know that’s stupid but I was trying anything. I even tried simply making the property a char *.

I’ve been researching this all day.

Help please.

Somewhere down the line, something is nil. try NSLogging the values of each object or data type.

NSLog(@"My first string is %@, the char is %s, the final string is %@", [_asset.defaultRepresentation.url absoluteString], c, self.imageCacheKeyBase);
