對不起一個人在上面改變回復。 使用url的編碼。

NSString * myurl = [yoururl stringByAddingPercentEscapesUsingEncoding：NSUTF8StringEncoding];

Answer 2

- （IBAction爲）buttonPressed：（ID）發送{

NSLog(@"button pressed"); 

//|=%7c [pipe], you can used NSString *myurl=[yoururl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 

NSString* myurl=@"your google chart url"; 

NSMutableURLRequest *theRequest=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:myurl] cachePolicy:NSURLRequestUseProtocolCachePolicy 
                timeoutInterval:60.0];            

NSURLResponse* response; 
NSError* error; 
NSData *imageData=[NSURLConnection sendSynchronousRequest:theRequest returningResponse:&response error:&error]; 
NSLog(@"%@",error); 
NSLog(@"%@",response); 
NSLog(@"%@",imageData); 

UIImage *myimage = [[UIImage alloc] initWithData:imageData]; 

self.ringImge.image=myimage;
