I have this method for button click (download). The problem is that it is terminating due to an exception:
[Session started at 2011-03-14 13:06:45 +0530.] 2011-03-14 13:06:45.710 XML[7079:20b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFString isFileURL]: unrecognized selector sent to instance 0x62b8'
-(IBAction) download
{
UIImage *image = [UIImage imageWithData: [NSData dataWithContentsOfURL:@"http://ws.cdyne.com/WeatherWS/Images/thunderstorms.gif"]];
[image release];
}
What is the problem?
It expects an NSURL as argument, not a string.
UIImage *image = [UIImage imageWithData: [NSData dataWithContentsOfURL: [NSURL URLWithString:@"http://ws.cdyne.com/WeatherWS/Images/thunderstorms.gif"]]];
EDIT:
To test if the data has loaded succesfully try something like
NSError* error = nil;
NSData* data = [NSData dataWithContentsOfURL:yourURL options:NSDataReadingUncached error:&error];
if (error) {
NSLog(@"%@", [error localizedDescription]);
[error release];
} else {
NSLog(@"Data has loaded successfully.");
}
