iOS BUG整理-Data argument not used by format string的警告处理

 NSError *error; NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:Online_Case_Lists]]; NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSArray *caselistarray = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error]; NSLog(@"列表",caselistarray);

 

 

如上代码~出现了这个警告，其实只是一时疏忽导致，没有写明输出的caselistarray的类型

改一下就好了。

 

NSError *error; NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:Online_Case_Lists]]; NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSArray *caselistarray = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableLeaves error:&error]; NSLog(@"列表%@",caselistarray);
