Error while attempting to output data onto console in xcode
I am trying to output general data (source code) from a website, but it just sits there. Can't figure out if its the interface or the code. Would someone double-check for me?
#import "Lockerz_RedemptionViewController.h"
@implementation Lockerz_RedemptionViewController
-(IBAction)start: (id) sender {
while (1) {
NSMutableData *mydata = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:@"http://ptzplace.lockerz.com/"]];
NSString *output = [[开发者_运维技巧NSString alloc] initWithData:mydata encoding:NSASCIIStringEncoding];
NSLog(output);
}
}
The reason your NSLog doesn't work is it should use format strings.
Replace:
NSLog(output);
With:
NSLog(@"%@",output);
For more info see http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/Strings/Articles/FormatStrings.html
Why the while(1)? Are you intentionally trying to set up an infinite loop? You should just run this once, or maybe set up a periodic timer to reload it every few seconds, but certainly don't use an infinite loop for that... also it's been a while since I did anything with Cocoa networking, but you might want to look into NSURLRequest. You also may want to try NSData's dataWithContentsOfURL:options:error: and check the error parameter to better see what might be going wrong. Hope this helps you out.
