我正在努力将CollectionView添加到我已创建的自定义容器中。我之前使用过Container来托管UITableView，但从来没有使用过CollectionView。它也不是那么难。只是以为我不得不围绕poof切换一些单词它会起作用！但遗憾的是那不是事情的方式。相反，我只是收到崩溃通知。
我的程序一直在崩溃。
//0. Remove the current Detail View Controller showed
if(self.currentDetailViewController){
[self removeCurrentDetailViewController];
}
有人可以帮我理解原因吗？
这是我的代码
#import "YourHome.h"
#import "HomePostTable.h"
#import "HomeStoryView.h"
@interface YourHome ()
@end
@implementation YourHome

NSLog(@"start query");
PFQuery *query = [PFQuery queryWithClassName:@"_User"];
// [query whereKey:@"photo" equalTo:[PFUser currentUser]];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error) {
UsersFilesArray = [[NSArray alloc] initWithArray:objects];
NSLog(@"%@", UsersFilesArray);
//PFObject *imageObject = [PFUser currentUser];
for (PFObject *imageObject in UsersFilesArray) {
// NSLog(@"%@", object.objectId);
PFFile *ImageFile = [imageObject objectForKey:@"photo"];
[ImageFile getDataInBackgroundWithBlock:^(NSData *data, NSError *error) {
if (!error) {
_ProfilePic.image = [UIImage imageWithData:data];
Background.image = _ProfilePic.image;
_ProfilePic.layer.cornerRadius = _ProfilePic.frame.size.width / 2;
_ProfilePic.clipsToBounds = YES;
_ProfilePic.layer.borderWidth = 2.0f;
_ProfilePic.layer.borderColor = [UIColor whiteColor].CGColor;
}
else {
NSLog(@"errrrrrr");
}
}];
}
}
}];
}
