ios 自訂載入動畫效果，ios自訂載入動畫

在開發過程中，可能會遇到各種不同的情境需要等待載入成功後才能顯示資料。以下是自訂的一個動畫載入view效果。

    

在UIViewController的中載入等到效果，如下

- (void)viewDidLoad {    [super viewDidLoad];        //將view背景顏色變更為黃色    self.view.backgroundColor = [UIColor yellowColor];        //在self.view上載入提示框    [[BIDActivityNote sharedInstance] AddActivityView:self.view];        //延時3分鐘後移除提示框    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{        [[BIDActivityNote sharedInstance] RemoveActivityView];    });}

BIDActivityNote.h 實現代碼

BIDActivityNote.m 代碼實現效果：
