IOS8 AlertView和ActionSheet不兼容问题解决方案
具体代码附文末。先演示一下怎么使用。
AlertView的情况
- (void)creatAlertView
{
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"title" message:@"message" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];
[alertView show];
}
#pragma mark UIAlertViewDelegate
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
switch (buttonIndex) {
case 0:
break;
case 1:
break;
default:
break;
}
}
#pragma mark Use NewObject(AlertView)
- (void)creatAlertView
{
BOAlertController *alertView = [[BOAlertController alloc] initWithTitle:@"title" message:@"message" viewController:self];
RIButtonItem *cancelItem = [RIButtonItem itemWithLabel:@"取消" action:^{
}];
[alertView addButton:cancelItem type:RIButtonItemType_Cancel];
RIButtonItem *okItem = [RIButtonItem itemWithLabel:@"确定" action:^{
}];
[alertView addButton:okItem type:RIButtonItemType_Destructive];
[alertView show];
}
ActionSheet的情况
- (void)creatActionSheet
{
UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"title" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"确定" otherButtonTitles:@"其它功能", nil];
[actionSheet showInView:self.view];
}
#pragma mark UIActionSheetDelegate
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
switch (buttonIndex) {
case 0:
break;
case 1:
break;
default:
break;
}
}
#pragma mark Use NewObject(ActionSheet)
- (void)creatActionSheet
{
BOAlertController *actionSheet = [[BOAlertController alloc] initWithTitle:@"title" message:nil viewController:self];
RIButtonItem *cancelItem = [RIButtonItem itemWithLabel:@"取消" action:^{
}];
[actionSheet addButton:cancelItem type:RIButtonItemType_Cancel];
RIButtonItem *okItem = [RIButtonItem itemWithLabel:@"确定" action:^{
}];
[actionSheet addButton:okItem type:RIButtonItemType_Destructive];
[actionSheet showInView:self.view];
}
使用这个封装类需要扩展类UIAlertView-Blocks的支持。下载地址https://github.com/jivadevoe/UIAlertView-Blocks
