所以,我正试图在我的iPhone应用程序中运行此代码,但应用程序仍在崩溃。任何解决方案?
- (IBAction)logOutBtnDown:(id)sender {
[PFUser logOut];
NSArray *quotes;
int r;
quotes = [NSArray arrayWithObjects:
@"R u done yet",
@"Log in again",
@"Try Me",
@"SMD",
@"We can do this all day",
@"IDC your eating up ur RAM",
"Please just connect to the servers",
@"You are not giving up are u",
@"Forget it I quit",
@"Imma tell TDK",
nil];
r = arc4random() % 10;
[_welcomeLabel setText:[NSString stringWithFormat:@" %@", [quotes objectAtIndex: r]]];
}

错过放置@,同时添加对象..
