NSlogging and NSString Conundrum


Tag : objective-c , By : WellBeing

hop of those help?
Here is a sample NSLog after pushing the first cell, then the second (ignore the nil view controller log, I think it's a bug. Also, the down Log is from a private method in the second view, so it can also be ignored. And a bonus to those who can resolve the CGContextClipToRect: invalid context 0x0 warning)
musicInteractionController = [[xSheetMusicViewController alloc]init];

may help you . If you need it decoupled from any particular class, using the preprocessor and C is your best bet. Something like this should work just fine.
#define NSBOOLLog(x) CFILogBoolean(#x, x)

extern void CFILogBoolean(char *propertyName, BOOL val);

void CFILogBoolean(char *propName, BOOL val) {
    printf("%s is set to %s", propName, (val ? "YES" : "NO"));
}

To fix the issue you can do The scenario is this: , Create an array with the names/labels you want to apply and use this:
NSArray *arrayOfLabelTexts=[NSArray arrayWithObjects:@"Label1", @"Label2", nil];
cell.label.text=[arrayOfLabelTexts objectAtIndex:indexPath.row];

wish helps you There is an easier way to get the sqlite location:
println(NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as NSString)
/Users/tooti/Library/Developer/CoreSimulator/Devices/AB5B3350-F891-420B-88D5-E8F8E578D39B/data/Containers/Data/Application/38FBDC42-0D09-4A10-A767-17B576882117/Documents
NSLog(NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as NSString )
2015-01-23 23:31:57.373 RAACTutor[6551:140531] /Users/tooti/Library/Developer/CoreSimulator/Devices/AB5B3350-F891-420B-88D5-E8F8E578D39B/data/Containers/Data/Application/38FBDC42-0D09-4A10-A767-17B576882117/Documents

NOT NULL by itself outputs correctly. Adding NOT NULL, AND and OR outputs nulls

wish help you to fix your issue How does one combine the NOT NULL with the AND and OR? , You have to prioritize your logic (i.e. use parenthesis) :
where rate_spread is not null and 
     (action_taken = 1 or action_taken = 6);
