}
-(void)getFriendPic:(NSString *)_friendID{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSString *str =[NSString stringWithFormat:@"http://www.3softcanada.com/ipictures/Image%@.png",_friendID];

NSData *imageData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:str]];
UIImage *theImage= [[UIImage alloc] initWithData:imageData ];
avatar.image = theImage;
[pool release];
}
推荐答案
您可能需要将selector:@selector(getFriendPic)
替换为selector:@selector(getFriendPic:)
.你错过了一个冒号.
You probably need to replace selector:@selector(getFriendPic)
with selector:@selector(getFriendPic:)
. You missed a colon.
