UIAlertView
我感觉UIActionSheet和UIAlertView的用法差不多，想用哪个，根据公司要求和个人爱好。
#import "ViewController.h"
@interface ViewController ()<UIAlertViewDelegate>
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
UIButton *button1 = [UIButton buttonWithType:UIButtonTypeSystem];
button1.frame = CGRectMake(100, 100, 100, 50);
button1.backgroundColor = [UIColor lightGrayColor];
[button1 setTitle:@"button1" forState:UIControlStateNormal];
[button1 addTarget:self action:@selector(showAlertView:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button1];
}
- (void)showAlertView:(UIButton*)button {
//Cancel，OK1，OK2，OK3，它们的buttonIndex分别为0，1，2，3
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Hehe" message:@"这是一行描述信息" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK1",@"OK2",@"OK3", nil];
alertView.delegate = self;
[alertView show];
}
-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if (0 == buttonIndex) {
NSLog(@"0000000000");
} else if (1 == buttonIndex) {
NSLog(@"1111111111");
} else if (2 == buttonIndex) {
NSLog(@"2222222222");
} else {
NSLog(@"3333333333");
}
}
- (void)alertViewCancel:(UIAlertView *)alertView{
NSLog(@"alertViewCancel");
}
-(void)willPresentAlertView:(UIAlertView *)alertView{
NSLog(@"willPresentAlertView");
}// before animation and showing view
- (void)didPresentAlertView:(UIAlertView *)alertView{
NSLog(@"didPresentAlertView");
}// after animation
- (void)alertView:(UIAlertView *)alertView willDismissWithButtonIndex:(NSInteger)buttonIndex{
NSLog(@"willDismissWithButtonIndex");
}// before animation and hiding view
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex{
NSLog(@"didDismissWithButtonIndex");
}// after animation
// Called after edits in any of the default fields added by the style
- (BOOL)alertViewShouldEnableFirstOtherButton:(UIAlertView *)alertView{
NSLog(@"alertViewShouldEnableFirstOtherButton");
return YES;
}
@end
