修改警告信息的宽和高

Question

想要将弹出的警告框修改为一个小一点的。

-(void)alertMessage1:(NSString*) title:(NSString*) message1  {

UIAlertView *alert1 = [[UIAlertView alloc] initWithTitle:@"Successfully uploaded!" message:message1 delegate:self cancelButtonTitle:@"Okay" otherButtonTitles:nil];

}

Answer 1

可以创建一个UIAlertview：

UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Title Here" message:@"Message here" delegate:self cancelButtonTitle:nil otherButtonTitles:nil];
                    [alert setDelegate:self];
                    [alert show];
                    [alert release];

如果调整框架：

- (void)willPresentAlertView:(UIAlertView *)alertView {
alertView.frame = CGRectMake(20.f, 200.f, 280.f, 93.f);
NSArray *subViewArray = alertView.subviews;
for(int x=0;x<[subViewArray count];x++){
    if([[[subViewArray objectAtIndex:x] class] isSubclassOfClass:[UILabel class]])
    {
        UILabel *label = [subViewArray objectAtIndex:x];
        label.textAlignment = UITextAlignmentLeft;
    }

}
}

在这句 alertView.frame = CGRectMake(20.f, 200.f, 280.f, 93.f) ; 是CGRectMake(X坐标, Y坐标, 宽, 高)。修改数值应该就可以了。
