#import "UIScrollView+EmptyDataSet.h"

遵守协议

`@interface MainViewController : UITableViewController

(void)viewDidLoad

{

[super viewDidLoad];

self.tableView.emptyDataSetSource = self;

self.tableView.emptyDataSetDelegate = self; // A little trick for removing the cell separators self.tableView.tableFooterView = [UIView new];

返回单张图片

Data Source 实现方法

- (UIImage *)imageForEmptyDataSet:(UIScrollView *)scrollView {

return [UIImage imageNamed:@"empty_placeholder"];

}

返回标题文字

- (NSAttributedString *)titleForEmptyDataSet:(UIScrollView *)scrollView {

NSString *text = @"Please Allow Photo Access";

NSDictionary *attributes = @{NSFontAttributeName: [UIFont boldSystemFontOfSize:18.0f], NSForegroundColorAttributeName: [UIColor darkGrayColor]}; return [[NSAttributedString alloc] initWithString:text attributes:attributes];

}

返回详情文字

- (NSAttributedString *)descriptionForEmptyDataSet:(UIScrollView *)scrollView{

NSString *text = @"This allows you to share photos from your library and save photos to your camera roll.";

NSMutableParagraphStyle *paragraph = [NSMutableParagraphStyle new]; paragraph.lineBreakMode = NSLineBreakByWordWrapping;

paragraph.alignment = NSTextAlignmentCenter;

NSDictionary *attributes = @{NSFontAttributeName: [UIFont systemFontOfSize:14.0f], NSForegroundColorAttributeName: [UIColor lightGrayColor], NSParagraphStyleAttributeName: paragraph}; return [[NSAttributedString alloc] initWithString:text attributes:attributes];

}
