Answer 1

NSString *fullStr = @"00000000:termometr2: +26.9 st.C";
NSArray *parts = [fullStr componentsSeparatedByString:@" "];
textField.text =[NSString stringWithFormat:@"%@",[parts objectAtIndex:1]];

Answer 2

它可能会帮助您：

NSArray *_array = [yourString componentsSeparatedByString:@":"];
[myTextField setText:[_array lastObject]]; // or any other component you want

Answer 3

只需这样做，使用方法stringByReplacingOccurrencesOfString: withString:：

NSString *originalString = @"~00000000:termometr2: +26.9 st.C";
NSString *filteredString = [originalString stringByReplacingOccurrencesOfString:@"~00000000:termometr2: " withString:@""];
