iOS BUG整理-Data argument not used by format string的警告處理

 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);

 

 

如上代碼~出現了這個警告，其實只是一時疏忽導致，沒有寫明輸出的caselistarray的類型

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);
