[wuzhenda]

in my ios7 project the iToast not show,but in other project it works fine. so I debug into the source code find if I change as this it works fine. so some guy like me may need this.

• UIWindow *window = [[[UIApplication sharedApplication] windows] objectAtIndex:0];
• UIWindow *window=[[[UIApplication sharedApplication] delegate] window];
