Other options are described below in the Methods section. 22 | 23 | myLabel.method = UILabelCountingMethodLinear; 24 | 25 | When you want the label to start counting, just call: 26 | 27 | [myLabel countFrom:0 to:100]; 28 | 29 | You can also specify the duration. The default is 2.0 seconds. 30 | 31 | [myLabel countFrom:0 to:100 withDuration:5.0f]; 32 | 33 | The full signature is: 34 | 35 | [myLabel countFrom:(float)startValue 36 | to:(float)endValue 37 | withDuration:(NSTimeInterval)duration]; 38 | 39 | ## Formats ##### 40 | 41 | When you set the `format` property, the label will look for the presence of `%(.*)d` or `%(.*)i`, and if found, will cast the value to `int` before formatting the string. Otherwise, it will format it using a `float`. 42 | 43 | If you're using a `float` value, it's recommended to limit the number of digits with a format string, such as `@"%.1f"` for one decimal place. 44 | 45 | Because it uses the standard `stringWithFormat:` method, you can also include arbitrary text in your format, such as `@"Points: %i"`. 46 | 47 | ## Modes ##### 48 | There are currently four modes of counting. 49 | 50 | ### `UILabelCountingMethodLinear` ##### 51 | Counts linearly from the start to the end. 52 | 53 | ### `UILabelCountingMethodEaseIn` ##### 54 | Ease In starts out slow and speeds up counting as it gets to the end, stopping suddenly at the final value. 55 | 56 | ### `UILabelCountingMethodEaseOut` ##### 57 | Ease Out starts out fast and slows down as it gets to the destination value. 58 | 59 | ### `UILabelCountingMethodEaseInOut` ##### 60 | Ease In/Out starts out slow, speeds up towards the middle, and then slows down as it approaches the destination. It is a nice, smooth curve that looks great, and is the default method. 61 | -------------------------------------------------------------------------------- /UICountingLabel/UICountingLabel.h: -------------------------------------------------------------------------------- 1 | #import 2 | #import 3 | 4 | typedef enum { 5 | UILabelCountingMethodEaseInOut, 6 | UILabelCountingMethodEaseIn, 7 | UILabelCountingMethodEaseOut, 8 | UILabelCountingMethodLinear 9 | } UILabelCountingMethod;
