UIAlertview代码= 1上的EXC_BAD_ACCESS [英] EXC_BAD_ACCESS on UIAlertview code=1

问题描述

我在[alert show]行上获得了EXC_BAD_ACCESS.

I am getting the EXC_BAD_ACCESS on [alert show] line.

我为什么要得到这个?

 alert = [[UIAlertView alloc]initWithTitle:@"Application Alert" message:@"all date popup" delegate:self cancelButtonTitle:nil otherButtonTitles:@"Update",nil];

 [alert show]; //EXC_BAD_ACCESS on this line

推荐答案

只需将委托设置为nil，不要将self应用于委托.请按如下所示对其进行编码

Just make delegate nil ,don't apply self to delegate .code it like below

alert = [[UIAlertView alloc]initWithTitle:@"Application Alert" message:@"all date popup" delegate:nil cancelButtonTitle:nil otherButtonTitles:@"Update",nil];

[alert show];

如果您在委托中使用self，则必须使用警报委托方法

if you are using self in delegate then you will have to use alert delegate method

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

然后它将不会给出EXC_Bad_Excess.让我知道它是否有效.. !!!!快乐的编码....

then it will not give EXC_Bad_Excess.let me know if it works..!!!!happy coding....
