Question

Answer 1

要刪除空白空間：

str = [str stringByReplacingOccurrencesOfString:@" " withString:@""];

使用以下來檢測文本視圖中的站點或電話號碼。

textview.dataDetectorTypes = UIDataDetectorTypeAll;

Answer 2

NSString *cleanString = [dirtyString stringByReplacingOccurrencesOfString:@"http: //" withString:@"http://"];

不過，我想知道為什么您首先會得到這個奇怪的字符串。

Answer 3

NSString *str = @"hel lo";

[str stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];

Answer 4

要刪除空格，請使用以下代碼，

str = [str stringByReplacingOccurrencesOfString:@" " withString:@"%20"];
