Uiactivityindicatorview problems on iPhone 4 Device

Source: Internet
Author: User

During development, you need to use uiactivityindicatorview to display network conditions. There is no problem in running the simulator, but there is a problem in running the iPhone 4: If the style of uiactivityindicatorview is uiactivityindicatorviewstylewhitelarge, in this case, uiactivityindicatorview, iPhone 3gs, and 3G are not displayed on the white background.

The final solution is to use uiactivityindicatorviewstylegray for style and change its size to 37*37 so that it can be displayed on the white background.
