You are saying that the object return by getJsonData[#"status"]; is an array, but then you are check if with an integer :
NSArray *json2 = getJsonData[#"status"];
if(json2 == 0){
NSLog(#"Cannot login");
}
If you need to check whether the array return by status has values do it like thisL:
NSArray *json2 = getJsonData[#"status"];
if([json2 count] == 0){
NSLog(#"Cannot login");
}
If the object return for the node status is an integer then try this:
NSNumber *json2 = getJsonData[#"status"];
if([json2 integerValue] == 0){
NSLog(#"Cannot login");
}
