self.subscription = [[[RACObserve(photoModel, fullsizedData) filter:^BOOL(id value) {
return value != nil;
}]map:^id(id value) {
return [NSNumber numberWithFloat:1.0f];
} ]setKeyPath:@keypath(self.imageView.layer,borderWidth)onObject:self.imageView];
error log is:
Terminating app due to uncaught exception 'NSUnknownKeyException',
reason: '[<UIImageView 0x7b1a8510> setValue:forUndefinedKey:]:
this class is not key value coding-compliant for the key cornerRadius.
and i think if there is another way to react the value who's type is float,int and so on .i will accept it
You should use string instead of a @keypath
macro.
[... setKeyPath:"layer.borderWidth" onObject:self.imageView];
Or you can use the RAC macro which is much clearer.
RAC(self.imageView, layer.borderWidth)
= [[RACObserve(photoModel, fullsizedData) filter:^BOOL(id value) {
return value != nil;
}] map:^id(id value) {
return @1.0f;
}];
