Be careful, assertions may cause you to make circular references Nsassert

The circular references caused by the mutual reference between block and self are understood by everyone. On the following code (intercept section)

__weak typeof (self) weakself = self;

Self.jsbridgefunctiondic = @{

Jsbridgecallnativepage:

^ (Nsdictionary *data) {

NSLog (@ "Jsbridgecallnativepage");

Nsdictionary *params = [Data dictionaryforkey:@ "params"];

if (params) {

NSString *url = [params stringforkey:@ "url"];

if (Url.length > 0) {

Open a new page

}else {

Nsassert (YES, @ "URL cannot be empty"); }

}

}

}

There seems to be no problem, but the page does not release, puzzled no fruit, casually point to the code of Nsassert this assertion, found inside unexpectedly included a self. It is the circular reference caused by the goods.

Not much to say, please use Nscassert.
