由於iOS6我有一個非常奇怪的UIImages問題,導致應用程序崩潰。 完整方法是這樣的:iOS6 UIImage導致崩潰
NSURL *url = [NSURL URLWithString:@"http://api.twitter.com/1/users/show.json"];
NSDictionary *parametros = [NSDictionary dictionaryWithObjectsAndKeys:account.username, @"screen_name", nil];
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter
requestMethod:SLRequestMethodGET
URL:url
parameters:parametros];
[request setAccount:account];
[request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
if ([urlResponse statusCode] == 200) {
NSError *error_ = nil;
NSDictionary *userInfo = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error_];
UIImage *image = [UIImage imageWithData:[userInfo objectForKey:@"profile_image_url"]];
UIImage *image = [UIImage imageWithData:[userInfo objectForKey:@"profile_image_url"]];
dispatch_sync(dispatch_get_main_queue(), ^{
[_imageCache setObject:image forKey:account.username];
[ListAccount reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:NO];
});
}
}];
的問題發生在這條線
UIImage *image = [UIImage imageWithData:[userInfo objectForKey:@"profile_image_url"]];
這在iOS5的沒有問題。我似乎無法找到爲什麼或有同樣問題的人。任何建議將非常感激
崩潰如下:

什麼是實際碰撞? –
你可以NSLog userInfo並提供有關錯誤的信息? –
