iOS 7 の Twitter クライアントに取り組んでいます。私は Twitter API をあまり使ったことがなく、1.1 より前のことをしました。
アプリケーションのタイムラインにプロフィール写真をロードするのを手伝ってくれませんか?
私たちのコードは以下です。
.h ファイルは次のとおりです。
#import <UIKit/UIKit.h>
#import <Accounts/Accounts.h>
#import <Social/Social.h>
#import <Twitter/Twitter.h>
@interface FirstViewController : UIViewController <UITableViewDataSource , UITableViewDelegate> {
UIRefreshControl *myRefreshControl;
}
@property (nonatomic) IBOutlet UITableView *timelineTableView;
@property (nonatomic) NSArray *timelineArray;
@end
アプリケーションのタイムラインの .m は次のとおりです。
@interface FirstViewController ()
@end
@implementation FirstViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[self getTimeline];
myRefreshControl = [[UIRefreshControl alloc]init];
myRefreshControl.tintColor = [UIColor blackColor];
[myRefreshControl setAttributedTitle:[[NSAttributedString alloc]initWithString:@"Pull to Refresh"]];
[myRefreshControl addTarget:self action:@selector(refreshTimeline) forControlEvents: UIControlEventValueChanged];
[self.timelineTableView addSubview:myRefreshControl];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
