Break up long formatted NSString over multiple lines

Given the following line of Objective-C code:

[NSString stringWithFormat:@"\n Elapsed Time  \n Battery Level:  \n Torque:  \n Energy Used  \n Energy Regenerated:\n Cadence: \n Battery Temp: \n Motor Temp: \n Incline: \n Speed MPH: \n Speed KPH:\n Avg Speed MPH: \n Avg Speed KPH:\n Distance Miles:\n Distance Km: \n Time Date Stamp:\n"];

In 开发者_JAVA技巧Xcode or any code editor, is it possible to avoid having a very long string that must be read by scrolling across it in the editor?

Is there a way of breaking it up into multiple lines? I am finding that if I try to do this, the code will not compile, because the compiler reaches the end of a line and does not see the closing quotation mark (") for the string.

Does anyone know a way around this?

Yes there is. Adjacent strings will be concatenated for you by the compiler.

NSString *info = [NSString stringWithFormat:@"\n Elapsed Time  \n"
                      "Battery Level:  \n"
                      "Torque:  \n"
                      "Energy Used  \n"
                      "Energy Regenerated:\n Cadence: \n"
                      "Battery Temp: \n"
                      "Motor Temp: \n"
                      "Incline: \n Speed MPH: \n" 
                      "Speed KPH:\n"
                      "Avg Speed MPH: %f \n"
                      "Avg Speed KPH:\n"
                      "Distance Miles:\n"
                      "Distance Km: \n"
                      "Time Date Stamp:\n"];
NSLog(info);

This is more of an interesting feature than an useful answer, but...

    // your code goes with that indentation (1 tab = 4 spaces)
    NSString *myString = @"first line\
second line\
third line\
...\
last line";
    // next lines of codes

But you really have to mind the indentation, doing NSLog(@"%@", myString) for above, would result in: first linesecond linethird line...last line.

Now consider this example:

    // your code goes with that indentation (1 tab = 4 spaces)
    NSString *myString = @"first line\
    second line\
    third line\
    ...\
    last line";
    // next lines of codes

this would give: first lineXsecond lineXthird lineX...Xlast line", where those nasty X's would be replaced by 4 spaces (tabulator had 4 spaces in this case, and I couldn't get right formatting, sorry). So, additional spacing can really stop you from getting expected results.
