调试时Xcode中的无效ObjC对象错误

Question

As in screenshot, the debugger has last two object named [0] which is my two NSString *variables..

Both variable can not be assigned.. (i have initialised both..)

inquiryId=[NSString stringWithFormat:@"%@",[dictObj objectForKey:@"inquiry_id"]];

I am assigning from dictionary but it stays [0]

when i print the variable in log then it display as shown in image

I dont know which type of error is this..!!

Answer 1

可能是因为您正在将对象分配给NSString，请尝试以下代码：

inquiryId=[NSString stringWithFormat:@"%@",[dictObj valueForKey:@"inquiry_id"]];

Answer 2

I just Remove reference of My Viewcontroller & add it again...

That problem was related to something linking issue.!!
