我只想添加明显的按钮“在Safari中打开”
我怎么能以简单的方式做到这一点.
我怎么能以简单的方式做到这一点.
#pragma mark - Share the link
- (IBAction)activityButtonPressed:(id)sender {
NSString *textToShare = @"I just shared this from my App";
// UIImage *imageToShare = [UIImage imageNamed:@"Image.png"];
NSURL *urlToShare = [NSURL URLWithString:@"http://www.google.com"];
NSArray *activityItems = [NSArray arrayWithObjects:textToShare,urlToShare,nil];
UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:Nil];
//This is an array of excluded activities to appear on the UIActivityViewController
//activityVC.excludedActivityTypes = @[UIActivityTypeMessage,UIActivityTypeCopyToPasteboard,UIActivityTypeSaveToCameraRoll];
[self presentViewController:activityVC animated:TRUE completion:nil];
}
解决方法
因为nevo shalev说你需要子类
UIActivity class
这是一个例子：
UrlActivity.h
#import <UIKit/UIKit.h> @interface UrlActivity : UIActivity @end
UrlActivity.m：
#import "UrlActivity.h"
@implementation UrlActivity
- (NSString *)activityType
{
return @"your Custom Type";
}
- (NSString *)activityTitle
{
return @"Title to display under your icon";
}
- (UIImage *)activityImage
{
return [UIImage imageNamed:@"your icon.png"];
}
- (BOOL)canPerformWithActivityItems:(NSArray *)activityItems
{
// basically in your case: return YES if activity items are urls
}
- (void)prepareWithActivityItems:(NSArray *)activityItems
{
//open safari with urls (activityItems)
}
+(UIActivityCategory)activityCategory
{
return UIActivityCategoryShare; // says that your icon will belong in application group,not in the lower part;
}
@end
并在您的主文件(导入UrlActivity.h后)：
#pragma mark - Share the link
- (IBAction)activityButtonPressed:(id)sender {
NSString *textToShare = @"I just shared this from my App";
// UIImage *imageToShare = [UIImage imageNamed:@"Image.png"];
NSURL *urlToShare = [NSURL URLWithString:@"http://www.google.com"];
NSArray *activityItems = [NSArray arrayWithObjects:textToShare,nil];
// create an array with your custom activity and add it to the activityVC
NSArray *appActivities = [NSArray arrayWithObjects:[[UrlActivity alloc] init]]];
UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:appActivities];
//This is an array of excluded activities to appear on the UIActivityViewController
//activityVC.excludedActivityTypes = @[UIActivityTypeMessage,UIActivityTypeSaveToCameraRoll];
[self presentViewController:activityVC animated:TRUE completion:nil];
}
