Objective C Logging by Example
You would have already seen using NSLog in the hello world example. A simple example is shown below.
int main(int argc, const char * argv[]) { // Autoreleasepool used in main for automatic memory management. @autoreleasepool { int a = 5; NSLog(@"Log value is %d",a); } return 0; }
You can see in the above example how to use NSLog. You need to use the type formatters like %d, %f, %s, %@ for integer, float, string and objects respectively.
